Our take on the Klipsch KW-120-THX
Professional-grade THX home theater sound
How sturdy is your home's foundation? Well you'd better check it twice before you fire up this dynamic duo. That's because Klipsch designed the KW-120-THX subwoofer and matching KA-1000-THX amplifier to deliver intense levels of movie theater bass that'll rattle your floorboards. This two-piece Klipsch system has more than enough output to rock most rooms. But if your home theater is extra-large, the amp is ready to power a second KW-120-THX sub. A pair of these beasts will satisfy your cravings for even more bass, and meet the stringent requirements for THX Ultra2 certification.
Use KW-120-THX subs and KA-1000-THX amplifers, along with Klipsch's other THX certified speakers, to create your own ultimate THX home theater.
Meet the new boss
The KW-120-THX subwoofer is 80 pounds of pure, unadulterated bass thunder. Built around a 12" cast-frame, long-throw driver with a massive 15-pound magnet structure, this sub can deliver staggering output without breakup or distortion.Klipsch's ultra-light yet rigid Cerametalic™ woofer cone material helps keep the bass tight and accurate. The sub also features a professional-grade NL2 SpeakOn™ input for a secure amplifier connection, and includes a 20-foot THX Ultra certified speaker cable with NL2 SpeakOn connectors.
To ensure years of top-notch performance, Klipsch builds their THX certified speakers to the highest standards. The sub's front-ported enclosure features the same interlocking panel construction found in their professional speakers for maximum structural integrity and strength. Premium-quality internal wiring is used for superior signal transfer and clarity. And Klipsch finishes off the KW-120-THX with a beautiful and durable fascia of black brushed aluminum.
Clean power for smooth bass
The subwoofer system is packaged here with Klipsch's custom-matched KA-1000-THX amplifier. This full-featured Class D amp provides 500 watts of clean power for high-impact, low-distortion bass and is capable of delivering 1000 watts into a 4 ohm load for driving two high-performance subs. It also includes a built-in, defeatable low-pass crossover and level control, boundary-gain compensation switch, continuously variable phase control, and an auto power function for exceptional flexibility. Finished in black with a machined aluminum front panel and knobs, the amp's standard chassis width and handsome appearance allow it to fit in easily with your other components.
