QSC K-SUB Lightweight Powered Subwoofer
The QSC K Series is quite simply The New Standard in lightweight powered loudspeaker systems. Under the direction of Pat Quilter, QSC's team of amplifier engineers have created a new standard in Class D power modules unparalleled in the industry.Features
- Lightweight portable powered speakers with legendary QSC amplifier power and reliability
- 1000 watt continuous Class D power module
- Extensive DSP enhances system performance
- Attractive and professional appearance
- Rugged birch plywood enclosure
- Tour-grade 18 gauge steel grilles
- Comfortable ergonomic handles
Remote gain control capability is offered via a potentiometer (not included) connected to the on-board Euroblock connector. In an installed application, multiple K Series speakers can be "daisy-chained" for total gain control from a single remote pot. Auto-standby mode is engaged after 5 minutes of inactivity.
Extensive DSP
- DMT™ (Directivity Matched Transition) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones.
- Intrinsic Correction™, first featured in our high-end line-array products maps 65-75 spacially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat bandpass target. The result is a speaker that behaves equally well across the entire sound field.
- DEEP™ and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies.
- GuardRail™ protection, first introduced on our GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping.
