QSC KW181 Active Subwoofer
Ultra-efficient, Earthshaking Subwoofer! 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 sub offers excellent connectivity, with XLR/TRS combo inputs that accept mic or line signals. Direct XLR line outputs are provided for each channel. Extensive internal DSP includes Intrinsic Correction, DEEP, and GuardRail technologies to provide terrific sonic clarity and component protection for reliable operation. Onboard control options allow you to adjust EQ to perfectly match your surroundings and applications. You can also use the rear-panel Phoenix connector to connect an external potentiometer (not included) for remote gain control. The sub has a standard 35mm pole socket and a threaded pole for securely mounting a loudspeaker on top of the subwoofer. It also has ergonomic cast-aluminum handles and low-noise casters for easy transport.

Direct XLR line outputs are provided for each channelIntrinsic Correction maps 65-75 spatially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat bandpass target, for excellent performance across the entire sound fieldDEEP technology and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequenciesGuardRail protection technology protects both the amplifier module and your performance from unnatural and destructive clippingMultiple EQ modes let you optimize the sub's output for specific applications with the flip of a switchThe onboard LED indicator can be set to illuminate when power is on, to only illuminate when the clip limiter circuit is engaged, or to always be offThe rear-panel Phoenix connector allows you to connect an external potentiometer (not included) for remote gain control.
