Experience a new "low" in listening

It's hard to beat THIEL speakers for their pinpoint accuracy and clarity. Same for their subs. THIEL's USS SmartSub® delivers dynamic, low-distortion bass that pairs up perfectly with THIEL speakers, as well as other high-quality speaker systems. Its powerful 550-watt amplifier easily drives the front-firing 10" woofer — giving you deep, room-shaking low frequency effects from your favorite movies and clear, musical bass with your favorite tunes. The potent USS uses THIEL's exclusive SmartSub® technology to ensure exceptional performance, no matter where you place it in the room. Unlike traditional subs, it doesn't have a built-in crossover — so be sure to connect it to your home theater receiver's dedicated LFE (Low Frequency Effects) output, or use it with the THIEL PX05 passive crossover for full bass reproduction in an all-THIEL speaker system.

Precision engineering for awe-inspiring bass

A massive aluminum cone woofer delivers deep, punchy bass.

The woofer consists of a rigid aluminum driver and a heavy cast aluminum chassis. This solidly constructed driver maintains the proper shape as it moves, for crystal-clear sound reproduction, even when you crank up the volume. A motor structure consisting of a short, 6-layer voice coil sitting inside a large, double-stacked magnet effortlessly drives the woofer. Unlike the voice coils found in most speakers that extend outside the magnet, the deliberately short voice coil always "sees" the optimum magnetic field as it travels back and forth. This eliminates distortion caused by variances in magnetic strength. Unique electronic circuitry is also used to correct for compression distortion due to heating of the voice coil for more dynamic and effortless performance under heavy loads. It all adds up to thunderous bass that's fast, detailed, and articulate.

Advanced controls on the back of the sub make it easy to compensate for nearby walls, ensuring better bass response.

Smooth bass response — no matter where you put the sub

Placing any subwoofer against the wall or in a corner will produce uneven bass response due to dips and peaks at certain frequencies. THIEL ingeniously solved this problem with patented room-correction circuitry. Simply use the controls on the back of the sub to dial in the distance to the rear wall and nearest side wall, and the sub automatically calibrates itself to correct for boundary problems. You'll hear smooth and balanced bass no matter where you put the sub in your room. Best of all — the USS does this compensation without microphones, equalizers, or complicated measurements.
