The same minds that engineered JL Audio's reference-grade Fathom® and Gotham® powered subwoofers have created amazing in-wall subwoofer solutions, centered on purpose-engineered, thin-line drivers with patented technology. The results are in-wall subwoofer systems fully worthy of the Fathom® name, with outstanding low frequency extension, dynamics and sound quality—and all the signal processing features of their in-room counterparts. Each Fathom IWS system consists of one or two in-wall cabinets, plus an outboard, rack-mountable amplifier.
Robert Harley reviewed our dual 13.5-inch IWS system (IWSv2-SYS-213), and wrote about it in the December 2019 issue of The Absolute Sound":
"JL Audio's IWS in-wall subwoofer system doesn't just rival the performance of generic freestanding subwoofers; it rivals the performance of JL Audio's freestanding subwoofers, which is an entirely different proposition. If you want uncompromised bass performance in a room that won't easily accommodate3 freestanding subwoofers, there's only one game in town."
"As for the low-frequencies themselves, their delivery was classic JL Audio—a combination of an extremely powerful, dynamic, extended, iron-fisted quality on one hand, and a remarkable resolution of dynamics, pitch and texture on the other."
