Product Specifications

The world's finest theater operators choose Klipsch cinema systems because they deliver the full impact of the most intense action movie soundtracks without sacrificing musical definition. When designing the KW-120-THX subwoofer, Klipsch applied its theater experience to bring the same powerful, deep-driving bass to the comforts of home. To achieve intense, deep-bass output in large rooms, this high-performance subwoofer that is part of the THX(R) Ultra2 family features a 12-inch, long-throw Cerametallic(TM) driver and front-firing port. It includes a 15 pound motor structure and a 20-foot Monster(R) THX Ultra cable with Neutrik Speakon(R) connectors. The subwoofer is driven by an external 1-kilowatt amplifier (KA-1000-THX sold separately) tailored to its characteristics for maximum output and reliability with extremely low distortion. The subwoofer's enclosure has the dado and rabbet construction used in Klipsch professional speakers for structural integrity. Finished in Galaxy black with an aluminum fascia, the KW-120-THX also features top-of-the-line internal wiring to ensure that every roar or explosion is heard with complete clarity.
