Bring the BOOM with QSC's most popular subwoofer (for good reason), the QSC KW181 Powered Subwoofer. This earth-shaking beast consists of an QSC 18-inch subwoofer within a premium birch cabinet, low-noise casters, a 1000 watt Class D power amplifier, and built-in DSP, featuring a threaded pole receptible for wobble-free stability.

The KW Series pushes the widly successful K series a step further into the world of wood enclosures. The system engineers (or possibly magicians) over at QSC have somehow managed to port over the game-changing electronic attributes of the K series while also designing a product that is both smaller and significantly lighter than the wood enclosure speakers that came before it.

Smaller than most other 18" subwoofers and yet somehow still making them pale in comparison, the QSC KW181 Powered Subwoofer's snarling bass output guarantees you get the best possible sound whether you're mobile or installing it. The built-in crossover, limiter, and additional rack components have been engineered in dummy-proof fashion to ensure that you have the best possible sound right out of the box.
