Klipsch KW-120-THX Subwoofer - BOOM!


How sturdy is your home's foundation? Well you'd better check it twice before you fire up this sub. That's because Klipsch designed the KW-120-THX subwoofer to deliver intense levels of movie theatre bass that'll rattle your floorboards. This Klipsch subwoofer has more than enough output to rock most rooms. The KW-120-THX also meets the stringent requirements for THX Ultra2 certification.

The KW-120-THX is a compact, high-output, low-distortion passive subwoofer suitable for use in any high-performance home-theatre or music system. 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.
