The JL Audio Fathom IWS Subwoofer Range offers discreet bass mastery with four variations—8″ Single In-Ceiling, 8″ Single In-Wall, Dual 8″ In-Ceiling, and Dual 8″ In-Wall—delivering up to 600W of hidden power. Designed for audio connoisseurs seeking powerful bass without visible clutter, it integrates seamlessly into walls or ceilings with a ported enclosure and Digital Automatic Room Optimization (D.A.R.O.). Available at Len Wallis Audio, the JL Audio Fathom IWS Subwoofer Range redefines in-wall and in-ceiling audio performance.

Why Choose the JL Audio Fathom IWS Subwoofer Range?

The JL Audio Fathom IWS Subwoofer Range is a specialized solution for audiophiles who want powerful bass without compromising room aesthetics. Available in 8″ single or dual configurations, it offers flexible in-wall or in-ceiling installation options.

The Dual 8″ model delivers 600W of short-term power, while the 8″ single offers 300W for deep, impactful bass. The Absolute Sound in 2019 reviewed the single in-wall, praising its “astonishing low-end power” in a hidden design.

Both models reach down to 24.9 Hz (±1.5 dB), capturing deep rumbles with precision in a ported enclosure. The design ensures a 10% tighter bass response compared to traditional in-wall subwoofers, thanks to optimised port tuning.

The amplifier weighs just 6.12 kg, with a slim 44 mm height for easy rack mounting. The subwoofer’s compact grille (267 mm x 267 mm) blends seamlessly into your wall or ceiling for a clean look.

Not sure how to optimise bass in a tricky room? The Fathom IWS’s D.A.R.O. technology auto-calibrates settings with a separately sold microphone, while variable phase (0 to 280°) and filter controls (30 Hz to 130.1 Hz) fine-tune performance.

It features RCA inputs and Neutrik speakON outputs for secure connectivity. A 12V trigger output (150 mA) allows integration with home automation systems for effortless control.
