Dedicated Reference Amplification & DSP for Custom Theater Subwoofers | Available at Trimira Audio
The JL Audio Fathom® SAv2 Home Subwoofer Amplifier is a dedicated high-power amplification and DSP platform designed to drive compatible JL Audio Fathom® subwoofer systems, including architectural and custom-theater installations.
Combining high-current Class-D amplification, an integrated DSP platform, and D.A.R.O. (Digital Automatic Room Optimization), the SAv2 provides the power and processing required to integrate high-output subwoofers into demanding dedicated cinema environments.
At Trimira Audio, we recommend the Fathom SAv2 for custom home theaters using compatible JL Audio architectural subwoofers where external amplification, room optimisation, and system-level bass control are required.
Key Features & Technological Innovations
High-Current Outboard Power Engine
The SAv2 platform provides substantial continuous RMS power, with 1000 W or 2000 W options depending on the model, giving compatible Fathom subwoofer systems the electrical headroom required for high-output cinema playback.
The external amplifier architecture also keeps substantial power-handling circuitry outside the architectural subwoofer enclosure.
Digital Automatic Room Optimization — D.A.R.O.
Integrated D.A.R.O. provides automated room calibration.
Using the supplied calibration microphone, the system measures the listening environment and applies DSP correction to address low-frequency room response.
This is particularly useful for architectural subwoofers because wall and boundary placement can significantly influence bass response.
Advanced Onboard DSP
The SAv2 provides extensive digital adjustment capabilities for subwoofer integration, including controls for:
- Low-pass filtering
- Filter slope
- Phase
- Polarity
- Boundary gain
- Infrasonic filtering
- Overall subwoofer level
These controls allow the subwoofer to be integrated more precisely with the main loudspeakers and cinema processor.
Thermal Management
The amplifier platform incorporates dedicated heatsinking and active cooling designed for sustained high-output operation in rack-mounted or AV-cabinet installations.
Flexible Input & Control Architecture
The SAv2 supports both:
- Balanced XLR input
- Unbalanced RCA input
Additional control facilities include 12V trigger functionality, making the amplifier suitable for integration with sophisticated home-automation and cinema-control systems.

System Integration
The SAv2 is particularly well suited to architectural subwoofer installations where the amplifier needs to be located remotely from the visible listening area.
A typical custom cinema system can combine:
AV Processor → SAv2 Amplifier → Fathom Architectural Subwoofer
This architecture allows the subwoofer enclosure to remain concealed behind an acoustically transparent screen, fabric wall, false wall, or custom baffle while the amplification and DSP remain accessible in the equipment rack.
For multi-subwoofer installations, system design should account for individual subwoofer placement, amplifier channel allocation, phase alignment, and room-calibration requirements.
