Unseen Power, Unmatched Performance

Powerful, Invisible Performance

THX Ultra-Certified Bass

Achieve cinema-quality bass performance at home without the need for large, obtrusive enclosures. Our in-wall subwoofer systems deliver authoritative, deep bass that's completely invisible, fitting seamlessly into standard walls.

Superior Sound Delivery

Dual 8-inch Long-Throw Woofers

Our braced MDF enclosure accommodates a dual 8-inch long-throw woofer assembly, providing the same cone area as a single 12-inch woofer but with better control and lower distortion. Experience cleaner output and greater resolution of low-level details.

Rock-Solid RMS Power

SA-380 Monoblock Amplifier

The SA-380 delivers a robust 380 watts RMS, providing the power needed for exciting, authoritative theater bass. Its linear power discrete Class G circuitry ensures reliable performance, even during high power peaks.

Precision Performance

Servo-Control Circuitry

Our servo-control circuitry monitors the woofers' performance and corrects any detected distortion in real-time. This results in high output levels at unusually low distortion levels, ensuring your audio experience is always top-notch.

Inconspicuous Design

IN-BOX-8e Sub Enclosure

Designed for installation before the sheet rock goes on, only a discrete grille is visible in the room. While the grill extends into the room to accommodate the high excursion of the woofers, its smoothly radiused compound curves make it very inconspicuous.

*Requires separate SA-380 amplifier and In-BOX-8eSub. In-BOX-8eSub is required to be purchased with IWTS-8eSUB, in order to achieve THX certification.
