Audiomobile GTS 10” Ported Subwoofer System

🔧 What "Complete System" Means for Your Installation

Pre-Assembled Configuration: The Audiomobile GTS 2110 10" subwoofer arrives professionally mounted inside the Pro-Line X Micro Series ported enclosure with all internal wiring completed at the factory. The driver is secured to the manufacturer-specific front baffle using precision hardware, the voice coil terminals are connected to the enclosure's external terminal cup with premium internal wire, and the entire assembly is quality-tested before shipping.

No Fabrication Required: Unlike purchasing separate components where you must source an appropriate enclosure, calculate port dimensions, cut mounting holes, wire terminals, and seal joints, this complete system arrives ready for immediate installation. Simply connect your amplifier's speaker outputs to the terminal cup, secure the enclosure in your vehicle, and begin enjoying professionally-tuned bass performance.

Guaranteed Acoustic Compatibility: The GTS 2110 subwoofer's parameters (500W RMS power handling, 12-14mm Xmax, optimized VAS for micro-box applications) are perfectly matched to the Pro-Line X Micro Series enclosure's 0.6 cubic foot net volume and 37 Hz port tuning. This factory-engineered pairing ensures you're operating within the driver's optimal performance envelope—no guesswork about whether your enclosure is too large, too small, or incorrectly tuned.

Space-Saving Advantage: At just 22.5" W × 14" H × 6.5" D, this complete system occupies an extraordinarily compact footprint while delivering ported enclosure output advantages. The 6.5-inch shallow depth is particularly significant—most ported enclosures require 12-15+ inches of depth to accommodate adequate port length for low-frequency tuning, but Pro-Line X's advanced V-Port engineering achieves 37 Hz tuning in this ultra-shallow envelope.

📐 Revolutionary Compact Dimensions: 22.5" × 14" × 6.5"

The 6.5-Inch Depth Achievement: This system's 6.5-inch shallow depth represents an extraordinary engineering accomplishment in ported enclosure design. Traditional ported enclosures typically require 12-15+ inches of depth to accommodate port tubes or slot ports of sufficient length to achieve low-frequency tuning without port noise (chuffing). Pro-Line X's Micro Series overcomes this limitation through advanced V-Port geometry—a carefully-calculated port design with carpet grooving that maximizes effective port area and length within the ultra-shallow 6.5" depth envelope, enabling clean 37 Hz tuning without the bulk of conventional ported designs.

Installation Flexibility: The compact 22.5" × 14" × 6.5" footprint enables installation locations impossible for conventional ported subwoofer systems. Behind truck seats (crew cab configurations), under SUV rear cargo floors, in sedan trunk corners beside spare tire wells, or in compact car hatchback areas—this system fits where larger ported enclosures simply cannot. The shallow 6.5" depth is particularly advantageous for vehicles with limited vertical or horizontal clearance, allowing ported bass performance in installations previously restricted to sealed enclosure compromises.

Minimal Cargo Intrusion: Despite being a ported design (which traditionally requires larger enclosures than sealed equivalents), this complete system occupies just 2,047.5 cubic inches (22.5 × 14 × 6.5) of vehicle space. For comparison, a typical 12" ported enclosure might measure 29" × 15" × 13" (5,655 cubic inches)—nearly 2.8 times the volume. This space efficiency preserves valuable cargo capacity while delivering the output advantages of ported bass response.

📅 The Audiomobile Timeline: Innovation Across Five Decades

1975-1979: The Founding Vision
Audiomobile was established in Costa Mesa, California during the formative years of car audio, when mobile sound systems were transitioning from simple AM radio upgrades to serious high-fidelity installations. The company's founding philosophy centered on developing subwoofers specifically engineered for automotive environments—understanding that vehicle interiors present unique acoustic challenges (boundary loading, cabin gain, space constraints) requiring purpose-built solutions rather than adapted home audio designs.

1976: Industry-First Innovation
Audiomobile became the first car audio manufacturer to display an actual vehicle inside their trade show booth—a revolutionary move that demonstrated products in realistic installation contexts rather than abstract bench displays. This customer-focused approach to product demonstration set the tone for Audiomobile's philosophy: real-world performance matters more than laboratory specifications.

1980s: The K40 Era and Legendary Status
During the 1980s, Audiomobile was acquired by K40 Electronics (famous for radar detectors and CB equipment), which provided resources for expanded research and development. This period established Audiomobile's legendary reputation for subwoofer testing supremacy—their drivers consistently delivered measured performance that matched or exceeded published specifications, earning trust from serious enthusiasts and professional installers who demanded verifiable results rather than marketing exaggeration.

1990s-2000s: The Resurrection Cycles
Like many specialist brands, Audiomobile experienced complex ownership transitions during the consolidation era of car audio. The brand was shuttered, then resurrected multiple times as various entities recognized the value of the Audiomobile name and intellectual property. Each resurrection brought renewed commitment to the original "push the envelope" mission—maintaining continuity with the brand's heritage of advanced engineering while incorporating contemporary technologies.

2010s-Present: The Modern Audiomobile
The current incarnation of Audiomobile represents a full return to the founding philosophy: developing subwoofers that challenge conventional limitations through innovative engineering. The GTS Series (featuring Isobaric design DNA), GT2 Series, and Evo Series (incorporating SMG shaped manifold gap technology) demonstrate Audiomobile's continued commitment to solving difficult problems—delivering high performance in compact enclosures, maintaining long excursion in shallow mounting depths, and achieving competition-grade power handling in space-constrained applications.

💡 The GTS Innovation: Isobaric Performance in a Single Driver

Audiomobile's Breakthrough: The GTS Series represents a revolutionary engineering achievement—a single subwoofer driver that replicates the key performance characteristics of a dual-driver Isobaric system through proprietary internal architecture. Rather than requiring two separate drivers mechanically coupled together, the GTS incorporates design elements that simulate Isobaric acoustic behavior within a single motor structure. This breakthrough delivers the primary Isobaric advantages (increased power handling, reduced VAS for micro-box optimization) without the cost, complexity, and power consumption of traditional two-driver configurations.

How It Works: While Audiomobile protects specific proprietary details as trade secrets, the fundamental principle involves optimizing the motor geometry, suspension compliance, and acoustic impedance characteristics to mimic how two drivers would interact in a compound Isobaric system. The result is a subwoofer that performs as if two discrete drivers are working together—doubling effective power handling capacity while enabling exceptional performance in enclosures as small as 0.33 cubic feet (for the GTS 2110 10-inch model). This "Isobaric design DNA" allows a single 10-inch GTS driver to deliver output and power handling approaching what would typically require a dual-driver Isobaric configuration.

Practical Benefits: For the end user, GTS Series Isobaric DNA translates to remarkable real-world advantages. You purchase one subwoofer instead of two (significant cost savings), connect to a single amplifier channel without complex wiring (installation simplicity), consume half the electrical power (reduced alternator/battery demands), yet achieve output performance and micro-box optimization previously available only through expensive, complex dual-driver Isobaric systems. This makes high-performance bass accessible in applications where traditional solutions simply don't fit—compact cars, crew cab trucks, space-constrained SUVs, and installations where cargo space preservation is critical.

🔊 500W RMS Power Handling: Thermal Validation

Conservative Rating Philosophy: The GTS 2110's 500W RMS (continuous) power handling specification represents genuine thermal capacity validated through extended testing—not "peak," "maximum," "musical," or other inflated marketing metrics. Audiomobile rates power handling based on how much continuous amplifier output the subwoofer can safely dissipate as heat without voice coil failure, adhesive degradation, or performance compromise over extended operating periods.

What 500W RMS Means Practically: You can connect this subwoofer to a quality 500-watt RMS amplifier (at 4-ohm load) and operate at full output for hours during extended listening sessions, road trips, or competition demonstrations without thermal damage or performance degradation. The dual bi-radial delta cooling vents continuously circulate air through the voice coil gap, preventing excessive temperature buildup. The voice coil former material, adhesive systems, and tinsel lead connections are all engineered to withstand the thermal stress of 500-watt continuous operation.

Amplifier Matching Guidance: For optimal performance, pair the GTS 2110 with an amplifier rated for 400-500 watts RMS at 4 ohms. This power range fully utilizes the subwoofer's capabilities without exceeding thermal limits. Quality amplifier choices include monoblock Class D designs from manufacturers like Arc Audio, JL Audio, Rockford Fosgate, or Kicker—prioritizing clean power delivery with low distortion rather than simply chasing maximum wattage numbers. Remember: 500 watts of clean power from a quality amplifier delivers dramatically better results than 750+ watts from distortion-prone budget alternatives.

🎯 The 6.5-Inch Depth Challenge: Ported Enclosure Engineering

Why Depth Matters for Ported Designs: Ported enclosures achieve their output and low-frequency extension advantages through precisely-tuned port tubes or slot ports that create a Helmholtz resonance—the enclosure airspace and port dimensions form a tuned acoustic system where port length, cross-sectional area, and internal volume determine the resonance frequency. Lower tuning frequencies require longer ports, while adequate port area is necessary to prevent air velocity from exceeding limits that cause audible noise (port chuffing). Traditional ported enclosures typically require 12-15+ inches of depth to accommodate port tubes or slot ports of sufficient length for low-frequency tuning (32-38 Hz range) without excessive air velocity.

The Micro Series Solution: Pro-Line X achieves 37 Hz tuning in just 6.5 inches of enclosure depth through advanced V-Port geometry with carpet grooving—a sophisticated port design that maximizes effective port length and cross-sectional area within the ultra-shallow dimensional envelope. Rather than using straight port tubes (which would be too short at 6.5" depth) or simple slot ports (which would have insufficient length), the V-Port configuration employs strategic internal baffling to create a folded port path that effectively increases port length beyond the physical 6.5-inch enclosure depth. The carpet grooving serves dual purposes: maintaining laminar airflow at port boundaries (reducing turbulence and chuffing potential) while creating clean aesthetic appearance.

Engineering Trade-Offs: Achieving 37 Hz tuning in 6.5" depth requires accepting some compromises compared to deeper ported designs. The port cross-sectional area is necessarily smaller (limited by shallow depth), which means power handling before port chuffing becomes audible is somewhat reduced compared to larger ported enclosures. However, for typical listening scenarios and the GTS 2110's 500W power handling, the Micro Series port design provides adequate area—chuffing would only become noticeable at extreme output levels beyond normal listening volumes. The sophisticated V-Port geometry demonstrates Pro-Line X's commitment to engineering problem-solving rather than simply declaring "you need a bigger box."

🛡️ One-Year Warranty: Structural Integrity Guarantee

Pro-Line X backs the Micro Series enclosure with a one-year warranty covering internal air leaks and joint failure when used properly. This warranty demonstrates manufacturer confidence in the Dado interlocking joinery, adhesive quality, and assembly procedures—properly-constructed enclosures should maintain acoustic seal integrity indefinitely under normal operating conditions. The warranty excludes damage from misuse (excessive power causing subwoofer mechanical failure that damages the enclosure, physical impact damage during installation, water damage from vehicle leaks) but covers manufacturing defects in materials or workmanship.

🎯 Choosing Between GTS and Evo Series

Choose GTS Series When:

• Your primary constraint is enclosure volume (need smallest possible box)
• You want ported enclosure advantages in compact dimensions (like this system)
• You have 4.5" mounting depth available (not ultra-shallow requirement)
• You prefer micro-box flexibility (GTS works well in 0.33-0.65 cu.ft. range)
• You want Isobaric performance benefits without dual-driver complexity
• Your amplifier provides 400-500W RMS (matching GTS power handling)

Choose Evo Series When:

• Your primary constraint is mounting depth (under-seat truck installations)
• You need absolute maximum excursion in shallowest possible profile
• You have only 3.9" mounting depth available (0.6" advantage over GTS)
• You prefer sealed enclosure accuracy (Evo optimized for sealed designs)
• You want exotic SMG motor technology (shaped manifold gap geometry)
• Your amplifier provides 500-600W RMS (matching Evo power handling)

Practical Perspective: Both GTS and Evo Series represent exceptional engineering achieving performance levels that would be considered impossible by conventional standards. The GTS excels when enclosure volume is the primary constraint and you want the smallest possible box or desire ported enclosure advantages. The Evo excels when mounting depth is the limiting factor and you need absolute minimum height profile. Either series dramatically outperforms mainstream shallow-mount subwoofers from mass-market manufacturers—the choice between them depends on your specific installation's dominant constraint (volume vs. depth) rather than one being objectively "better" than the other.

Crew Cab Truck Behind Rear Seats: The 6.5-inch shallow depth makes this system ideal for crew cab truck installations where clearance behind rear seats is extremely limited. Position the enclosure horizontally with the port opening facing toward the cab interior (not blocked against the rear wall). The compact 22.5" width typically fits between wheel well intrusions in most full-size trucks. Secure using bungee cords, ratchet straps, or fabricated mounting brackets to prevent movement during aggressive driving.

SUV Rear Cargo Area: Place the system in rear cargo areas of SUVs, CUVs, and crossovers where the 6.5" depth allows positioning under cargo covers or against rear seatbacks without significant intrusion into usable cargo space. The plush black carpet finish protects against scratches when loading/unloading cargo around the enclosure. Orient the system so port opening faces into the vehicle interior rather than toward cargo doors (maintains acoustic coupling to cabin space).

Sedan Trunk Corner Placement: The compact 22.5" × 14" footprint enables corner installation in sedan trunks, preserving central trunk space for spare tires, cargo, or amplifier mounting. Position along the rear trunk wall or side walls, ensuring the port opening isn't blocked by trunk lining or cargo. The shallow 6.5" depth often allows placing the enclosure behind wheel well arches where deeper enclosures wouldn't fit.

Compact Car Hatchback Installations: For hatchbacks and compact cars where trunk space is premium, this system's ultra-compact dimensions enable bass enhancement without sacrificing practicality. Consider rear corner placement, behind rear seats, or secured along sidewalls. The 35-38 lb total system weight is manageable for installation/removal when you need maximum cargo space for specific trips (furniture transport, vacation luggage).

🎯 Which System Matches Your Priorities?

Choose GTS 2110 Ported System When:

• Your primary constraint is DEPTH (need shallow 6.5" depth dimension)
• You prioritize maximum output and low-frequency extension (ported advantages)
• You listen primarily to bass-heavy music (hip-hop, EDM, pop, modern bass-focused genres)
• You have adequate HEIGHT clearance (14" tall) but limited DEPTH space
• You want 37 Hz deep bass extension for chest-thumping impact
• You can position the enclosure with 2-3" port opening clearance
• You prefer conventional upward/forward firing orientation flexibility

Choose Evo 2410 Downfire System When:

• Your primary constraint is HEIGHT (need ultra-low 6.5" profile)
• You prioritize transient accuracy and "tight" sealed bass response
• You listen to diverse genres including rock, jazz, classical (accuracy matters)
• You're installing under truck seats (the downfire "killer app")
• You want maximum excursion (16mm Xmax) in shallowest mounting depth (3.9")
• You value exotic SMG technology and premium Evo engineering
• You want floor reflection acoustic coupling advantages
• You prefer stealth appearance (virtually invisible installations)

Practical Perspective: Both systems represent exceptional engineering delivering professional-grade bass performance in ultra-compact dimensions. The GTS Ported emphasizes output and deep bass extension through ported efficiency and 37 Hz tuning—ideal for maximum impact and modern bass-heavy music. The Evo Downfire emphasizes transient accuracy and revolutionary low-profile design through sealed precision and exotic SMG motor technology—ideal for accurate bass response and extreme space constraints. Your installation's dominant dimensional constraint (depth vs. height) and musical preferences (impact vs. accuracy) determine which system best serves your needs.

Q: What does "complete system" mean for installation?

A: This arrives as a turnkey plug-and-play solution with the Audiomobile GTS 2110 subwoofer professionally mounted inside the Pro-Line X Micro Series enclosure, internally wired to the terminal cup, and ready to connect to your amplifier. No assembly, enclosure fabrication, or component matching required—simply connect speaker wires from your amplifier to the terminal cup, secure the system in your vehicle, and enjoy bass. This eliminates all the complexity of DIY subwoofer installations while guaranteeing acoustic compatibility between driver and enclosure.

Q: How does the GTS 2110 achieve ported performance in just 6.5" depth?

A: Pro-Line X's advanced V-Port geometry with carpet grooving represents sophisticated engineering that maximizes port length and cross-sectional area within the ultra-shallow 6.5-inch depth envelope. Traditional straight port tubes would be too short at 6.5" depth to achieve 37 Hz tuning, but the V-Port employs strategic internal baffling to create a folded port path that effectively increases port length beyond the physical enclosure depth. This allows low-frequency tuning (37 Hz) impossible for simple shallow port designs, delivering ported enclosure advantages (increased output, extended bass) in a footprint typically limited to sealed enclosures.

Q: What's the difference between GTS and Evo series within Audiomobile?

A: GTS Series features Isobaric design DNA that replicates dual-driver compound system performance in a single subwoofer, optimizing for smallest possible enclosures (0.33+ cu.ft. for 10") through reduced VAS. Evo Series features SMG (Shaped Manifold Gap) proprietary motor technology achieving maximum excursion (16mm Xmax) in shallowest mounting depth (3.9"). Choose GTS when enclosure volume is your primary constraint and you want micro-box flexibility or ported options. Choose Evo when mounting depth is your limiting factor and you need absolute minimum height profile (under-seat truck installations). Both represent exceptional engineering—the choice depends on your specific installation's dominant constraint.

Q: Can I use this system with my current amplifier?

A: This system's Single 4-Ohm impedance offers universal amplifier compatibility. Ideally, pair with a monoblock amplifier rated 400-500 watts RMS at 4 ohms for optimal performance. You can use amplifiers rated 300-600W, but understand the trade-offs: lower power (300W) prevents realizing full dynamic potential, while higher power (600W+) risks thermal damage if consistently operated at maximum volume. Most car audio amplifiers provide 4-ohm output capability, making this system compatible with existing equipment in many installations—just verify your amplifier's 4-ohm power rating matches the 400-500W RMS recommendation.

Q: What is Isobaric design DNA and why does it matter?

A: Traditional Isobaric systems mount two identical subwoofers in compound configuration (face-to-face or face-to-back) to double power handling while reducing required enclosure volume by 50%—but require purchasing two subwoofers, complex wiring, and double amplifier power. The GTS Series incorporates Isobaric design DNA—proprietary internal architecture that replicates key Isobaric performance characteristics (increased power handling, reduced VAS) within a single driver. This delivers Isobaric advantages (micro-box optimization, 500W power handling) without the cost and complexity of dual-driver systems. Practically, this means the GTS 2110 performs exceptionally well in tiny enclosures (0.33-0.65 cu.ft.) where conventional single subwoofers would struggle or fail.

Q: Where can I install this system in my vehicle?

A: The compact 22.5" × 14" × 6.5" dimensions enable installation in numerous locations: behind crew cab truck rear seats (6.5" shallow depth advantage), SUV/CUV rear cargo areas (preserves cargo space), sedan trunk corners (beside spare tire wells), compact car hatchbacks (space-efficient bass). The critical requirement is ensuring 2-3 inches clearance in front of the port opening—don't block port airflow against seats or walls. The plush black carpet finish protects against scratches during cargo loading/unloading, while the 35-38 lb total weight allows easy removal when you need maximum cargo capacity for specific trips.

Q: How does this compare to sealed enclosure systems?

A: Ported enclosures (like this system) provide approximately +3 dB output advantage and extended low-frequency response compared to sealed equivalents of similar size—you get louder bass and deeper extension. Sealed enclosures offer superior transient accuracy ("tighter" bass), simpler construction (no port tuning concerns), and more compact dimensions for equivalent driver size. This system delivers ported advantages (maximum output, 37 Hz extension) while maintaining remarkably compact 0.6 cu.ft. dimensions through advanced V-Port engineering. Choose ported when maximum impact and deep bass extension are priorities; choose sealed when transient accuracy and absolute smallest size matter most.

Q: Is this system suitable for competition SPL (sound pressure level)?

A: This system is designed as a high-performance daily driver / enthusiast solution prioritizing compact dimensions and installation flexibility rather than maximum SPL competition. While the GTS 2110's 500W power handling and ported enclosure provide impressive output for music enjoyment, serious SPL competition typically requires larger enclosures (2+ cubic feet), higher tuning frequencies (40-45+ Hz for peak SPL in competition frequencies), and subwoofers optimized specifically for SPL rather than space efficiency. For daily driving with impressive bass impact, this system excels; for trunk-flexing competition SPL, larger dedicated competition systems would be more appropriate.

Q: What amplifier brands pair well with this system?

A: Quality monoblock Class D amplifiers rated 400-500W RMS @ 4Ω from reputable manufacturers deliver optimal results. Consider brands like Arc Audio (American excellence, conservative ratings), JL Audio (industry-leading reliability), Rockford Fosgate (strong bass amplifier heritage), Kicker (proven performance), Alpine (Japanese precision), or Kenwood Excelon (value-oriented quality). Prioritize amplifiers with clean power delivery (THD under 1%), robust protection circuits, variable controls (low-pass crossover, subsonic filter, gain), and from manufacturers honoring published specifications. Avoid suspiciously cheap amplifiers claiming extraordinary power at bargain prices—they typically deliver distorted power causing premature subwoofer failure.

Q: Can I switch between series and parallel wiring configurations?

A: No—this system features a Single 4-Ohm voice coil configuration, which means there is only one voice coil with no wiring options. You connect it directly to your amplifier's 4-ohm output. This simplicity is actually an advantage for most installations: no complex wiring calculations, no impedance matching concerns, universal amplifier compatibility. The Single 4-Ohm design was intentionally chosen to maximize ease of installation and amplifier compatibility rather than offering multiple impedance options that add complexity without significant practical benefit for this application.
