To achieve intense, deep-bass output in large rooms, this high-performance subwoofer that is part of the THX® family features a 12-inch, long-throw Cerametallic™ driver and front-firing port. It includes a 15 pound motor structure and a 20-foot Monster® THX Ultra cable with Neutrik Speakon® connectors. The subwoofer is driven by an external 1-kilowatt amplifier (KA-1000-THX) 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.
