Details & Highlights

Details from Klipsch

    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.
