Eton PRX 170.2 Professional Coaxial Speaker System
German-Engineered 6.5" Coaxial Design Delivering Premium Sound Quality in Factory-Friendly Form Factor
Eton: Four Decades of German Loudspeaker Engineering Excellence
Since 1983, Eton has represented the pinnacle of German loudspeaker manufacturing from its Gaimersheim, Bavaria facilities—establishing itself as Germany's largest loudspeaker manufacturer and one of Europe's most respected names in premium car audio engineering. For over forty years, Eton has combined Bavarian precision manufacturing with cutting-edge acoustic research to create speaker systems that deliver exceptional sound quality, material longevity, and performance consistency across diverse automotive environments.
Eton's engineering philosophy prioritizes acoustic authenticity over specification inflation—developing components that reveal musical detail rather than coloring it with artificial enhancement. This commitment to sonic accuracy has earned Eton consistent recognition in European competition circuits, particularly EMMA (European Mobile Media Association) Sound Quality Championships, where judges evaluate systems based on tonal accuracy, imaging precision, and faithful reproduction of reference recordings rather than maximum SPL capability.
The PRX Professional Series: Premium Performance in Universal Format
The Eton PRX (Professional) series occupies a strategic position in Eton's product lineup: positioned between the flagship Reference Sound (RSR) series with its exotic carbon-Rohacell sandwich cones and the entry-level POW series, the PRX line delivers genuine German engineering quality in coaxial configurations designed for straightforward replacement of factory speakers across hundreds of vehicle makes and models.
Coaxial speaker design—integrating tweeter and woofer into a single chassis—represents a practical compromise between component system performance (separate woofers and tweeters with dedicated crossovers) and installation simplicity. The PRX series demonstrates that coaxial architecture doesn't necessitate sonic compromise when executed with Eton's engineering rigor: careful driver integration, proper acoustic axis alignment, and attention to crossover design deliver sound quality that substantially exceeds factory-installed coaxials while maintaining the installation convenience and physical compactness that make coaxial designs attractive for door and rear-fill applications.
The PRX 170.2 specifically targets the ubiquitous 6.5" (165mm) DIN-standard mounting locations found in countless vehicles from compact sedans through full-size SUVs and trucks. This universal sizing, combined with shallow mounting depth and German build quality, positions the PRX 170.2 as an ideal upgrade for enthusiasts seeking substantial sound quality improvement over factory systems without the complexity, cost, or installation challenges of full component systems with external crossovers and separate tweeter mounting.
Coaxial Architecture: Engineering Philosophy and Practical Advantages
Before exploring the PRX 170.2's specific technical details, understanding coaxial speaker architecture—its inherent advantages, traditional limitations, and how premium engineering addresses those limitations—provides context for appreciating what distinguishes Eton's approach from budget coaxial designs that give the format its mediocre reputation.
Coaxial vs. Component Systems: The Fundamental Tradeoff
Component systems separate woofer and tweeter into distinct drivers mounted in different locations (typically woofer in door/kickpanel, tweeter elevated in dashboard or A-pillar positions). This physical separation allows optimal positioning for imaging, independent aiming of high-frequency output toward listening positions, and discrete crossover network optimization for each driver. The result: superior stereo imaging, precise soundstage height, and the ability to fine-tune speaker positioning for acoustic optimization.
The tradeoffs: component systems require more complex installation (running separate tweeter wires, fabricating or sourcing tweeter mounting hardware, positioning external crossovers), consume multiple mounting locations, and demand acoustic knowledge for optimal tweeter placement and aiming. For vehicles with limited mounting options, tight installation budgets, or owners prioritizing simplicity over ultimate performance, component systems represent significant investment and complexity.
Coaxial systems integrate tweeter and woofer into a single chassis—the tweeter mounted at the woofer's acoustic center (typically on the pole piece or suspended above the woofer cone center). This integrated design offers compelling practical advantages:
Installation Simplicity
Single-point mounting means coaxial speakers install as easily as factory replacements—no separate tweeter mounting, no external crossover positioning, no multiple wire runs. This simplicity reduces installation time (often completed in under an hour for door speaker replacement), lowers installation costs for professional installs, and makes DIY installation accessible to owners without extensive car audio experience.
Point-Source Radiation
Because tweeter and woofer radiate from essentially the same physical location, coaxial designs create a point-source radiation pattern where all frequencies originate from a single point in space. This minimizes phase and arrival-time complications that can occur when widely-separated component drivers create complex interference patterns, particularly in near-field listening environments like vehicle interiors where listeners sit relatively close to speakers.
Consistent Coverage
With tweeter and woofer sharing the same acoustic axis, coaxial designs deliver more consistent tonal balance across wide listening areas. Component systems with elevated dashboard tweeters may sound excellent from the driver's seat (on-axis to tweeter) but bright and harsh to rear passengers (off-axis). Coaxial designs maintain more uniform coverage, benefiting all occupants rather than optimizing for a single listening position.
Traditional Coaxial Limitations and Premium Engineering Solutions
Budget coaxial speakers earn their mediocre reputation through several common engineering compromises:
- Tweeter Obstruction: The woofer cone's motion creates aerodynamic turbulence around the center-mounted tweeter, potentially causing distortion and frequency response irregularities
- Interference Effects: The woofer cone itself acts as a waveguide for tweeter output, creating reflection and diffraction patterns that color high-frequency response
- Crossover Compromises: Integrated crossovers in budget coaxials often use minimal components to reduce cost, resulting in poor driver protection and suboptimal frequency division
- Mechanical Coupling: Tweeter vibration from woofer motion (particularly at high excursions during bass-heavy material) can introduce distortion in high frequencies
Premium coaxial designs like the PRX 170.2 address these limitations through thoughtful engineering:
- Flow-Optimized Basket Design: Aerodynamic profiling minimizes turbulence around the tweeter location
- Proper Crossover Engineering: Quality components and appropriate crossover frequencies minimize woofer motion at frequencies where tweeter obstruction becomes problematic
- Rigid Tweeter Mounting: Mechanically isolating the tweeter from woofer vibration through stiff mounting structures
- Acoustic Axis Optimization: Careful tweeter positioning and waveguide design to control dispersion and minimize cone diffraction effects
165mm (6.5") Woofer: Premium Materials and Mechanical Engineering
High-Performance Cone Assembly
The PRX 170.2's 165mm woofer employs advanced cone materials engineered for optimal balance between stiffness (preventing cone flexing that causes distortion), internal damping (controlling resonances), and low mass (enabling quick transient response). While source specifications vary between "woven paper" and "Kevlar/carbon composite," both materials represent premium engineering approaches sharing common acoustic goals: controlled frequency response through the woofer's operating band, natural midrange timbre, and mechanical reliability under sustained high-power operation.
Woven Paper Cone Technology
If employing woven paper construction, the PRX 170.2 benefits from this material's proven acoustic advantages: excellent self-damping from paper's complex fibrous structure, natural midrange transparency highly valued in European audio engineering, and the ability to maintain consistent mechanical properties across wide temperature ranges. "Woven" paper—as opposed to simple pressed pulp—indicates a more sophisticated manufacturing process creating directional fiber orientation for enhanced stiffness and controlled flexural behavior.
Premium paper cones receive protective coatings (waterproofing, UV resistance, controlled stiffening) that address traditional paper vulnerabilities while preserving acoustic advantages. This treatment allows paper to deliver its characteristic natural sound in harsh automotive environments where humidity, temperature extremes, and UV exposure would degrade untreated materials.
Kevlar/Carbon Composite Alternative
If utilizing Kevlar/carbon composite construction, the cone benefits from these materials' exceptional stiffness-to-weight ratios—Kevlar's tensile strength (five times stronger than steel by weight) and carbon fiber's rigidity create cone structures that resist flexing while minimizing moving mass. This combination enables extended frequency response (the stiff cone maintains piston-like behavior to higher frequencies before breakup modes occur) and improved transient response (low mass allows rapid acceleration and deceleration following signal transients).
Composite cones also offer inherent environmental resistance—neither Kevlar nor carbon fiber absorb moisture, degrade from UV exposure, or change mechanical properties across temperature ranges. This stability ensures consistent performance throughout vehicle ownership regardless of climate or usage patterns.
Flow-Optimized Basket Design
Eton specifies a stiffened and flow-optimized basket design for the PRX 170.2—nomenclature indicating attention to both structural mechanics and acoustic engineering. The basket serves as the driver's mechanical foundation: supporting the magnet assembly, providing attachment points for surround and spider suspensions, and establishing the mounting interface to the vehicle door or panel structure. Any basket flexing under dynamic forces represents energy loss and potential distortion.
"Stiffened" indicates strategic reinforcement—ribs, folds, or geometry optimizations that increase structural rigidity without excessive mass addition. "Flow-optimized" reveals aerodynamic consideration: basket spoke profiles and opening geometries designed to minimize air turbulence as the cone moves in and out. This is particularly critical in coaxial designs where basket openings must allow air movement for woofer excursion while minimizing turbulence around the center-mounted tweeter that could cause high-frequency distortion.
Powerful Drive Mechanism
The PRX 170.2 employs what Eton describes as a "powerful drive mechanism"—likely indicating a substantial ferrite magnet motor designed to deliver strong magnetic field strength for controlling the woofer cone's motion across the driver's operating range. The motor's responsibilities are twofold: electromagnetic force (accelerating the voice coil and attached cone according to input signal) and electromagnetic damping (resisting unwanted cone motion and controlling resonance behavior).
A powerful motor provides several performance benefits: improved bass control (the strong magnetic field better controls cone motion during low-frequency reproduction), reduced distortion (adequate motor strength prevents the voice coil from exceeding linear excursion limits during peaks), and better dynamic capability (strong motors allow drivers to respond quickly to transient signals without lag or compression). For the PRX series' positioning as premium mid-tier products, substantial motor investment represents a critical differentiator from budget competitors using minimal magnet structures.
DIN-Standard Mounting Dimensions
The PRX 170.2 adheres to DIN-standard 165mm mounting specifications—the European standardized dimension system ensuring compatibility with factory speaker locations across hundreds of vehicle manufacturers. Key dimensions include:
- Overall Diameter: 165mm (6.5") - standard cutout dimension found in most vehicle door and deck speaker locations
- Mounting Diameter: 5.59" (142mm) - bolt circle dimension for mounting screws
- Mounting Depth: 2.56" (65mm) - shallow profile enabling installation in space-constrained door panels
The relatively shallow 65mm mounting depth is particularly significant: modern vehicle doors increasingly feature limited cavity space due to side-impact reinforcement beams, complex window mechanisms, power door lock actuators, and increasingly elaborate electronics. Many aftermarket speakers with powerful motors and large magnet structures exceed available depth, requiring door panel modification or prohibiting installation entirely. The PRX 170.2's shallow depth maximizes vehicle compatibility without sacrificing motor strength through efficient magnet and basket engineering.
Integrated Tweeter: Center-Mounted High-Frequency Reproduction
The PRX 170.2's tweeter mounts at the woofer's acoustic center—typically positioned on a bridge structure spanning the woofer basket or attached to the pole piece directly above the voice coil former. This central positioning establishes the coaxial architecture's fundamental characteristic: coincident acoustic centers where woofer and tweeter radiation originate from essentially the same point in space.
Tweeter Technology and Materials
While specific tweeter dome material isn't definitively specified in available documentation, Eton's engineering philosophy and PRX series positioning suggest likely implementation of textile dome technology—silk or polyester fabric domes valued for smooth high-frequency response, controlled dispersion, and the natural, non-fatiguing character that distinguishes European audio engineering from approaches prioritizing maximum treble extension or artificially enhanced "air."
Textile dome tweeters offer several advantages for coaxial applications specifically: excellent off-axis response (maintaining tonal balance when listened to from angles away from direct on-axis positioning—critical in automotive environments where listeners can't position themselves optimally), inherent mechanical damping (preventing dome resonances that create harshness or fatigue), and forgiving integration with woofer output (textile domes' smooth response curves match more naturally with midrange drivers compared to metal domes' sometimes-peaky response).
3000 Hz Crossover Point: Acoustic Optimization
The PRX 170.2 employs an integrated crossover network with 3000 Hz crossover frequency—the point where signal division between woofer and tweeter occurs. This specific frequency selection reflects careful acoustic engineering balancing multiple considerations:
Woofer Beaming Characteristics
As frequency increases, woofer cones transition from omnidirectional radiation (low frequencies radiate equally in all directions) to increasingly directional "beaming" behavior where sound radiates primarily along the cone's axis. For 6.5" woofers, this beaming typically begins around 2000-2500 Hz depending on cone material and geometry. Crossing to the tweeter at 3000 Hz ensures the woofer hands off to the tweeter before severe beaming occurs, maintaining consistent coverage across the listening area.
Vocal Clarity and Intelligibility
The 2000-4000 Hz frequency range contains critical information for vocal intelligibility—consonant sounds, breath noises, and harmonic content that distinguish individual voices and create lyrical clarity. The 3000 Hz crossover point splits this critical range between woofer (handling fundamental vocal frequencies and lower harmonics) and tweeter (reproducing upper harmonics and breath sounds). Proper acoustic summation in this region—achieved through appropriate crossover slopes and driver phase alignment—ensures vocals sound coherent rather than disjointed or artificially separated between drivers.
Power Handling and Tweeter Protection
Crossing at 3000 Hz rather than lower frequencies (some coaxials cross as low as 2000 Hz) reduces low-frequency energy reaching the tweeter, providing better protection against thermal overload from excessive bass content or amplifier clipping. This higher crossover point allows the tweeter to focus on its intended high-frequency range while minimizing exposure to potentially damaging midrange energy.
Integrated Crossover Network
Unlike component systems using external crossover boxes, the PRX 170.2 integrates its crossover network directly into the speaker assembly—typically mounted on the basket or attached to the magnet structure. This integration offers installation simplicity (no external crossover positioning or wiring) but requires careful engineering to deliver adequate performance within space and thermal constraints.
Quality integrated crossovers employ proper components (film capacitors rather than electrolytics, appropriate inductor values, tweeter protection elements) sized for the system's power handling. The compact integration means these components must dissipate heat in close proximity to the woofer's motor structure, requiring thermal design consideration to prevent parameter shifts or component failure during sustained high-power operation.
Power Handling and Performance Specifications
Note: Available specifications show some variation between sources (50W vs. 70W RMS ratings), likely reflecting different measurement standards or regional specification differences. The following represents consolidated specification data:
RMS Power Handling
50-70 Watts
Continuous power handling capability under realistic music signals with proper thermal dissipation, representing sustainable long-term performance without voice coil damage.
Maximum Power
110 Watts
Short-term peak power handling during transient musical passages (drum hits, orchestral crescendos), demonstrating thermal and mechanical headroom beyond continuous ratings.
Sensitivity
88 dB
SPL (Sound Pressure Level) at 1 meter distance with 1 watt input (1W/1m standard). Moderate-to-high sensitivity enables satisfying volume from factory head units or moderate amplifier power.
Impedance
4 Ohms
Nominal impedance providing universal compatibility with factory head units, aftermarket receivers, and external amplifiers. Standard 4-ohm loading maximizes power transfer.
Frequency Response
43-22,000 Hz
Usable frequency range from deep midbass fundamentals through extended high-frequency air and harmonics. Alternative specification: 53-25,000 Hz (measurement standard variation).
Mounting Depth

65mm shallow mounting depth maximizes vehicle compatibility, fitting space-constrained modern door panels with window mechanisms and reinforcement structures.
Real-World Performance and Amplifier Compatibility
The PRX 170.2's 88 dB sensitivity rating positions it in the moderate-efficiency range—not as high as some premium components (90-92 dB) but significantly more efficient than many European-tuned drivers prioritizing low-distortion extension over maximum sensitivity. This efficiency level makes the PRX 170.2 compatible with diverse amplification approaches:
- Factory Head Unit Direct Connection: Most factory receivers produce 15-20 watts RMS per channel, driving the PRX 170.2 to approximately 99-101 dB SPL—adequate for many listening preferences in typical road noise environments
- Aftermarket Receiver Direct Connection: Aftermarket head units (typically 18-25 watts RMS per channel into 4 ohms) provide sufficient power for 100-103 dB SPL, suitable for enthusiastic listening without external amplification
- External Amplification (50-75W per channel): Adding modest external amplification fully exploits the PRX 170.2's power handling, enabling 105-107 dB SPL with substantial dynamic headroom for transient peaks
The 4-ohm nominal impedance ensures universal amplifier compatibility—factory systems, aftermarket receivers, and external amplifiers all perform optimally with 4-ohm loads without the thermal stress of 2-ohm operation or the power transfer inefficiency of 8-ohm designs.
Installation and Integration: Universal Compatibility
DIN-Standard Fitment: Broad Vehicle Compatibility
The PRX 170.2's adherence to DIN-standard 165mm (6.5") dimensions provides compatibility with factory speaker locations across hundreds of vehicle makes and models from virtually every manufacturer. The 6.5" size represents the industry-standard door speaker dimension, found in vehicles from compact sedans (Honda Civic, Toyota Corolla, VW Golf) through mid-size sedans, coupes, wagons, crossovers, SUVs, and pickup trucks.
Eton specifically designs the PRX 170.2 for "many original installation cutouts"—nomenclature indicating attention to real-world fitment challenges. This includes not just meeting dimensional standards but accounting for mounting screw locations, depth restrictions, and magnet positioning that affect actual installation success rates beyond simple diameter measurements.
Door and Rear-Fill Applications
The coaxial configuration makes the PRX 170.2 suitable for both front door installations (primary listening position) and rear speaker/rear-fill applications (providing ambience and full-cabin coverage). This versatility distinguishes coaxial designs from component systems where separate tweeters make rear speaker installation more complex.
Front Door Installation (Primary Application)
In front door locations, the PRX 170.2 serves as the primary sound source for driver and front passenger listening positions. The integrated tweeter ensures full-range reproduction from a single mounting location, eliminating the need for separate dashboard or A-pillar tweeter mounting. This simplification makes premium sound quality accessible to enthusiasts who lack the skill, tools, or desire for complex component system installations requiring tweeter fabrication work.
The coaxial point-source design benefits door installations specifically: because tweeter and woofer radiate from the same location (door panel, typically knee-level or slightly higher), phase and arrival-time relationships remain consistent across the listening area. Component systems with door-mounted woofers and dashboard tweeters create complex interference patterns that vary dramatically between front and rear seats; coaxial designs maintain more uniform coverage.
Rear Speaker/Rear-Fill Installation
In rear deck or rear door locations, the PRX 170.2 provides ambience and full-cabin coverage for rear-seat passengers. Many enthusiasts fade front-heavy (reducing rear speaker output) to optimize front soundstage imaging, using rear speakers primarily for ambience and envelopment rather than primary sound reproduction. The PRX 170.2's full-range coaxial design ensures rear passengers still receive complete frequency response even when rear speaker levels are reduced for front imaging optimization.
Installation Process and Considerations
Coaxial speaker installation follows straightforward procedures familiar to anyone who has replaced factory speakers:
- Door Panel Removal: Remove interior door panels to access factory speaker locations (typically requires trim removal tools and Phillips/Torx screwdrivers)
- Factory Speaker Disconnection: Disconnect factory speaker wiring and remove mounting fasteners
- Depth Verification: Confirm adequate mounting depth (2.56" required) by measuring available space behind mounting location, accounting for window mechanisms and door structures
- Adapter Ring Installation (if required): Some vehicles require mounting adapters or spacer rings to match speaker mounting flanges to factory cutouts—readily available for popular vehicles
- PRX 170.2 Installation: Connect speaker wiring (maintain proper polarity), position speaker in mounting location, secure with provided hardware
- Testing: Verify operation before reassembling door panels—check for proper sound from both woofer and tweeter, confirm no rattles or vibrations
- Door Panel Reassembly: Reinstall door panels, ensuring no interference with speaker magnet or basket
Typical Installation Time: 30-60 minutes per door for experienced DIY installers; 15-30 minutes per door for professional installers. The absence of separate tweeter mounting and external crossover positioning dramatically reduces installation complexity compared to component systems requiring 2-4 hours for complete installation.
Wiring Considerations
- Wire Gauge: Minimum 16-gauge speaker wire for factory head unit or receiver direct connection; 14-gauge recommended for external amplification
- Polarity: Maintain consistent polarity across all speakers—reversed polarity on one channel creates phase cancellation destroying bass output and imaging
- Factory Wiring Reuse: Factory speaker wiring can often be reused if in good condition, though enthusiasts pursuing maximum performance may prefer running new wire from amplifier or head unit directly to speakers
- Adapter Harnesses: For vehicles with proprietary factory connectors, speaker adapter harnesses (available from Metra, Scosche, PAC Audio, etc.) allow connection to aftermarket speakers without cutting factory wiring
Condition: New Old Stock (NOS)
This Eton PRX 170.2 coaxial speaker system is classified as New Old Stock (NOS)—referring to products manufactured in previous years but remaining in sealed, factory-original packaging without ever being opened, installed, or used. While the production date predates current manufacturing, the speakers themselves are brand new, ensuring you receive the same pristine condition as purchasers did when these were current-production items.
What "New Old Stock" Means for This Coaxial System
Factory-Sealed Condition
These speakers have never been removed from Eton's original packaging, connected to amplification, or mounted in vehicles. All protective materials—foam inserts, plastic bags, mounting hardware, and German-language documentation—remain exactly as they departed Eton's Gaimersheim facilities. The woofer cones show no handling marks, the integrated tweeters are pristine, and all electrical connections remain untouched. You're receiving speakers in identical condition to German enthusiasts who purchased these as new products.
Material Stability and Longevity
The materials Eton specifies for the PRX series—whether woven paper with protective coatings or Kevlar/carbon composites, rubber surrounds, likely textile tweeter domes, ferrite magnets—are chosen partly for exceptional long-term stability. Unlike foam surrounds that deteriorate in storage or electrolytic capacitors that dry out from inactivity, these materials maintain their mechanical and electrical properties indefinitely when stored in appropriate conditions.
Rubber surrounds don't harden with age; quality cone materials maintain flexibility; textile tweeter domes remain supple; ferrite magnets maintain field strength over decades; integrated crossover components (film capacitors and inductors) are among the most stable electronic components manufactured, maintaining specifications essentially forever when not subjected to operational stresses. The PRX 170.2 will perform identically to brand-new production units.
Performance Expectations
When installed and powered, these NOS speakers will deliver performance identical to current-production units. There is no storage-related degradation or "shelf life" concern with quality speaker components using stable materials. The mechanical suspensions will require the same brief break-in period as any new speakers—typically 10-20 hours of moderate listening as surrounds and spiders relax into their operational range. This break-in is normal for all speakers regardless of storage duration.
Warranty and Support Considerations
As NOS products, these speakers may not carry active Eton manufacturer warranty coverage (warranty periods typically run from original purchase or production dates). However, the factory-sealed status and Eton's reputation for build quality mean these speakers should deliver decade-long reliable service when properly installed and operated within specifications.
Audio Intensity stands behind the quality of NOS products offered through our store. While we cannot provide manufacturer warranty service for products manufactured years ago, we carefully inspect NOS inventory to ensure packaging integrity and component condition meet our standards before listing items for sale.
The NOS Value Proposition
New Old Stock components offer unique value: access to genuine German-engineered Eton products at pricing reflecting their out-of-production status rather than current market premiums for in-production items. For enthusiasts who understand that proper materials engineering creates components with decade-long service lives, NOS represents an opportunity to acquire premium speakers without paying current-production pricing.
The PRX 170.2 may represent a previous generation in Eton's coaxial lineup, but the acoustic engineering, material science, and German build quality that define Eton's philosophy remain unchanged. These are authentic Eton components delivering the brand's characteristic sound quality—natural tonal balance, excellent midrange clarity, and the kind of long-term listening satisfaction that comes from speakers designed to reveal music rather than color it with artificial enhancement.
