Eton PRO175 2-way 6.5" Component System

Technical Specifications

German Acoustic Engineering: The Eton Difference

35+ Years of Hand-Crafted Precision

Eton has been developing and manufacturing high-end loudspeakers in Germany for over 35 years. Unlike mass-produced speakers assembled in offshore factories, every Eton component undergoes rigorous German quality control and benefits from artisan-level craftsmanship. The PRO175 represents this legacy—a component system where performance isn't sacrificed for cost, and where every design decision prioritizes natural sound reproduction over artificial enhancement.

Hand-Coated Paper Cone: Natural Midrange Authority

Why Paper Matters

While many modern car audio speakers use polypropylene, aluminum, or carbon fiber cones, Eton's hand-coated paper cone delivers a sonic signature that synthetic materials simply cannot replicate. Paper's natural damping characteristics eliminate the metallic coloration and harshness common in aluminum cones, while its controlled breakup modes create smooth, natural frequency response without the resonance peaks that fatigue the ear during extended listening.

• Hand-Coated Application — Each cone receives a proprietary hand-applied coating, ensuring consistent thickness and damping characteristics across the entire surface
• Air-Dried Process — Traditional air-drying (not forced-oven drying) allows the coating to cure naturally, preserving paper's inherent acoustic properties
• Controlled Breakup — Paper's progressive cone breakup extends usable frequency response without harsh resonances, enabling smooth integration with tweeters
• Natural Tonality — Vocals, acoustic instruments, and midrange details sound organic and lifelike without artificial emphasis or recession

Recommended Frequency Range: 50 Hz – 3,000 Hz

The woofer's extended frequency range means you're hearing midrange detail directly from the woofer, not artificially shifted to the tweeter. This reduces intermodulation distortion and preserves the natural timbre of vocals and instruments.

25mm Hand-Coated Fabric Dome Tweeter

Silky Highs Without Fatigue

The PRO175's 25mm (1-inch) fabric dome tweeter is hand-coated with Eton's proprietary damping compound, creating a high-frequency driver that delivers crystalline detail without the harshness or sibilance common in metal dome designs.

• Fabric Dome Advantages — Fabric's natural damping eliminates the ringing and resonance peaks found in aluminum or titanium domes, creating smooth, extended high-frequency response
• Hand-Applied Coating — Proprietary coating enhances stiffness without sacrificing fabric's inherent damping, extending frequency response while maintaining smooth tonality
• Wide Dispersion — Fabric dome's wide off-axis response creates a large "sweet spot," ensuring consistent sound quality across the entire front cabin
• Extended Listening Comfort — No metallic edge or listening fatigue—you can enjoy hours of music without harshness

Aluminum Die-Cast Basket: Precision Platform

Flow-Optimized Engineering

The PRO175's powder-coated die-cast aluminum basket isn't just structural support—it's a precision-engineered acoustic component that directly influences sound quality.

• Increased Rigidity — Die-cast aluminum provides superior strength-to-weight ratio compared to stamped steel, eliminating basket flex that causes compression and distortion
• Flow-Optimized Vents — Strategically positioned ventilation channels dissipate heat from the voice coil without creating air turbulence or chuffing noise
• Reduced Resonance — Powder-coated aluminum's inherent damping characteristics minimize basket resonance, preventing coloration of the acoustic output
• Corrosion Resistance — Powder coating protects against moisture and salt corrosion in marine or humid climates

Magnet System & Thermal Management

Ferrite Power with Optimized Cooling

The PRO175 uses a powerful ferrite magnet system paired with advanced thermal management to maintain performance during extended high-power use.

• Large-Core Bore Design — Oversized center bore allows heat from the voice coil to escape efficiently, preventing thermal compression
• T-Yoke Optimization — Specially designed T-yoke absorbs and dissipates heat generated by the magnet system, improving power handling
• Symmetric Magnetic Field — Precision assembly ensures perfectly symmetrical magnetic field, reducing distortion and improving transient response
• Gloss-Turned Baseplate — Machined base plate improves magnetic efficiency and provides visual elegance

Crossover Network with Level Adjustment

Precise System Integration

The included external crossover features adjustable tweeter level control, allowing fine-tuning to match your vehicle's acoustics and personal preferences.

• Passive Design — No external amplifier power required for crossover operation
• Level Adjustment — Dial tweeter output up or down to compensate for dashboard reflections or cabin acoustics
• High-Quality Components — Premium capacitors and inductors ensure clean frequency division with minimal insertion loss
• Flexible Mounting — Compact enclosure fits behind door panels or under seats

Installation Considerations

Shallow Mounting Depth: 66.4mm

At just 66.4mm (2.61 inches) mounting depth, the PRO175 fits most factory speaker locations without requiring extensive modification. The 8-screw circular mounting pattern provides flexibility for custom installations.

• Factory Door Locations — Fits most vehicles with 6.5" factory speaker cutouts
• Kick Panel Installations — Shallow depth allows creative placement for optimal staging
• Dashboard Installations — Tweeter size and mounting options provide flexibility for sail panel or A-pillar mounting

Sensitivity & Power Requirements

The PRO175's 90 dB sensitivity means it works exceptionally well with both factory head units (25–35W RMS) and aftermarket amplifiers (50–70W RMS). You don't need massive power to achieve reference-level sound quality.

Use Cases & Applications

Ideal For:

• Audiophile Factory System Upgrades — Extract maximum sound quality from factory head units without amplifier investment
• Reference-Level SQ Builds — Foundation for sound quality competition systems where natural tonality is paramount
• European/Luxury Vehicles — Matches the refined acoustic character of BMW, Mercedes-Benz, Audi, and Volvo interiors
• Jazz, Classical, Acoustic Music — Excels at reproducing natural timbre and tonal accuracy
