Built to compliment the QSC K series, the KW series is constructed using wood enclosures. The KW181 is an active sub with an 18” LF driver capable of thumping out 135dB maximum peak SPL using its ultra-efficient 1000-watt continuous Class-D power plant. The on-board DSP is fantastic, and like the rest of the K series, features QSC’s proprietary DEEP and Intrinsic Correction technologies to enhance system performance. This really is a sub that will add unbelievable ‘beef’ to your performance, and you will love the wealth of connection and control options on the back panel. The super-tough birch enclosure is also a joy, both oozing quality, and ensuring that you needn’t worry about a bump or two - this is a unit that will just keep on going and going!
