The KW181 from QSC is a professional-quality active 3-way PA loudspeaker. Ideal for low frequency reinforcement of KW-series loudspeakers, the lightweight and rugged birch cabinet houses an 18" woofer to deliver deep, thumping bass with frequencies as low as 35Hz. An efficient Class-D amplifier provides an output power of 1000W for strong audio with low distortion.

 The all-new DXS15 subwoofer delivers powerful yet focused low end reaching as low as 42Hz. The DXS’s fully optimized band-pass design combines with its powerful Class-D amplifier, long travel 15” woofer, and formidable DSP to deliver a tight, impressive bass with outstanding depth and high power output.

Delivering 1000 watts of continuous power and 2000 watts peak, the QSC KSub extends your sound reinforcement system's bass range down to a chest-thumping 44 Hz. The KSub is plenty powerful for DJ rigs, pushing out a thundering 130 dB maximum SPL, while its attractive housing and small footprint make it perfect for houses of worship or upscale performance venues that need extra low-end punch in a low-profile cabinet. Plus, with four built-in casters and ergonomic handles for easy load-in, it's ideal for mobile PA setups.
