Reference Single-Driver Sub-Bass Solution | Available at Trimira Audio
The JL Audio Fathom® f113v2 (F113v2-GLOSS-240V) is a high-performance powered subwoofer designed for demanding two-channel systems, dedicated home cinemas, and reference listening environments.
Built around a 13.5-inch ultra-long-throw driver, the f113v2 combines substantial excursion capability with a powerful integrated amplifier, rigid sealed enclosure, and JL Audio's D.A.R.O. (Digital Automatic Room Optimization) system.
At Trimira Audio, we recommend the f113v2 for listeners seeking deep, controlled low-frequency performance from a relatively compact single-driver subwoofer.
Key Features & Technological Innovations
13.5-Inch W-Cone Sub-Bass Driver
The f113v2 employs a 13.5-inch (345 mm) W-Cone driver incorporating JL Audio's long-excursion driver architecture, OverRoll surround geometry, and DMA-optimised motor structure.
The design is intended to maintain controlled motor behaviour during substantial cone excursion while providing the displacement required for deep, high-output bass.
3000-Watt RMS Internal Amplifier
A dedicated 3000 W RMS continuous amplifier provides substantial power reserves for demanding musical and cinematic material.
The high-efficiency switching power supply and Class-D output stage are designed to provide high-current driver control without requiring an external power amplifier.
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.
Its 18-band digital equalisation system helps address room-related peaks and boundary effects for a smoother response at the listening position.
Rigid Sealed Enclosure
The f113v2 uses a heavy-duty MDF cabinet with extensive internal matrix bracing.
The rigid sealed construction is designed to minimise:
- Cabinet flex
- Structural vibration
- Internal resonance
- Acoustic coloration
Front-Mounted Controls
Controls located behind the removable grille provide access to:
- Gain
- Crossover frequency
- Variable phase
- Polarity
- D.A.R.O. calibration
This allows the subwoofer to be configured without requiring an external control interface.

Two-Channel & Home-Cinema Integration
The f113v2 is particularly effective where a system requires substantial low-frequency extension without moving to a dual-driver enclosure.
Two-Channel
For high-end stereo systems, careful crossover, phase, level, and placement adjustment allows the f113v2 to extend the main loudspeakers into the sub-bass region while maintaining a cohesive presentation.
Home Cinema
The combination of the 13.5-inch driver, 3000 W amplifier, sealed enclosure, and D.A.R.O. provides substantial capability for demanding LFE content in dedicated cinema environments.
Installation Considerations
At 59 kg, the f113v2 requires appropriate consideration for delivery, positioning, and floor placement.
Trimira Audio can assist with:
- Subwoofer placement
- Crossover and phase integration
- D.A.R.O. calibration
- Stereo system integration
- Home-cinema LFE configuration
- Multi-subwoofer planning
- Room-acoustic optimisation
