12" THX Ultra2 Certified Passive Subwoofer KW-120-THX
The KW-120-THX is a compact, high-output, low-distortion passive subwoofer suitable for use in any high-performance home-theater or music system. A pair of KW-120-THXs driven by a KA-1000-THX amplifier meet all requirements for THX Ultra2 certification. Although a single KW-120-THX does not satisfy the stringent THX Ultra2 maximum output specification, which assumes a very large room, it is more than adequate for a typical small or medium-sized room. Either configuration is capable of intense, powerful deep-bass reproduction, with no loss of clarity or detail at even the highest levels demanded by modern action-movie soundtracks. The cabinet is front-ported to maximize installation flexibility

The KW-120-THX is built around a castframe, long-throw driver with a 12-inch Cerametallic cone. Propelling it is a powerful motor structure with a huge, 240-ounce magnet. This rugged, no-compromise driver is capable of staggering output without breakup or distortion.

Construction is to the highest standard, with a professional grade rabbet and dado locked panel cabinet and premium components throughout to ensure sonic purity, consistency, and reliability. Each subwoofer enclosure has a NL2 SpeakOn input for correct, secure amplifier connections, and each KW-120-THX is supplied with a 20-foot THX Ultra certified speaker cable terminated with NL2 SpeakOn connectors.

  • Very high output capability (130dB @ 30Hz)
  • 12" Cerametallic cast-frame, long-throw driver with 240-ounce magnet structure
  • Front-ported enclosure for maximum installation flexibility
  • NL2 SpeakOn inputs for correct, secure amplifier connection

To achieve intense, deep-bass output in large rooms, this high-performance subwoofer that is part of the THX Ultra2 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.Specifications:
