JL Audio Gotham® v2 Dual 13.5-inch (345 mm) Powered Subwoofer

The Unrivalled Flagship of Sub-Bass Performance | Available at Trimira Audio

The JL Audio Gotham® v2 (G213v2-GLOSS-240V) is a flagship powered subwoofer designed for uncompromising two-channel listening rooms, dedicated home cinemas, and reference-level entertainment spaces.

Combining dual 13.5-inch ultra-long-throw drivers, a powerful integrated amplifier, a rigid curved composite enclosure, and JL Audio's D.A.R.O. (Digital Automatic Room Optimization) system, the Gotham v2 is engineered to deliver extreme low-frequency output while maintaining control and accuracy.

At Trimira Audio, we recommend the Gotham v2 for reference systems where exceptional sub-bass authority, deep extension, and sophisticated room integration are required.

Key Features & Technological Innovations

Dual 13.5-Inch Ultra-Long-Throw Drivers

The Gotham v2 employs two 13.5-inch (345 mm) JL Audio subwoofer drivers with substantial motor structures and long-excursion suspension technology.

The dual-driver architecture provides enormous radiating area and excursion capability, allowing the system to generate very high acoustic output while maintaining controlled low-frequency reproduction.

4500-Watt RMS Internal Amplifier

A dedicated integrated amplifier delivers 4500 watts of continuous RMS power.

The amplifier incorporates a high-power switching supply and high-current Class-D output stage designed specifically for driving the Gotham's low-impedance subwoofer load.

This provides substantial electrical headroom for demanding cinematic effects and large-scale musical transients.

Hand-Crafted Fiberglass Composite Cabinet

The enclosure uses a substantial fiberglass composite construction with a curved profile.

The rigid cabinet architecture is designed to minimise:

• Cabinet flex
• Structural vibration
• Internal resonances
• Unwanted acoustic energy

The high-gloss black finish gives the Gotham v2 a distinctive flagship aesthetic suitable for dedicated listening environments.

Digital Automatic Room Optimization — D.A.R.O.

The integrated D.A.R.O. system uses the supplied calibration microphone to measure the room's low-frequency response and apply digital equalisation.

The system provides 18 bands of digital equalisation to address room-related peaks and improve bass consistency at the listening position.

Top-Mounted Control Interface

A dedicated control interface provides convenient access to key system functions including:

• Subwoofer level
• Crossover frequency
• Phase
• D.A.R.O. calibration

This allows basic adjustment without requiring external control hardware.

Technical Specifications

Reference Two-Channel & Home-Cinema Integration

The Gotham v2 is suited to systems where the subwoofer is expected to operate as a genuine reference component rather than simply providing additional bass.

Two-Channel

In a high-end stereo system, the Gotham can provide deep low-frequency extension while its phase, level, and crossover controls allow careful integration with the main loudspeakers.

Home Cinema

For dedicated cinema installations, the combination of enormous amplifier reserves, dual long-throw drivers, and D.A.R.O. provides the foundation for high-impact LFE reproduction.

Room geometry and subwoofer placement remain critical, particularly with a subwoofer capable of such substantial acoustic output.

Installation Considerations

At 163 kg, the Gotham v2 requires careful planning for delivery, positioning, floor loading, and final placement.

Trimira Audio can assist with:

• Delivery and positioning planning
• Listening-position optimisation
• Phase and crossover integration
• D.A.R.O. calibration
• Stereo subwoofer integration
• Home-cinema LFE configuration
• Room-acoustic assessment
