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
- Comfortable ergonomic handles
- Threaded pole socket with speaker pole included
The KSub is a dual-12" bandpass design, constructed of premium birch and
includes high-quality, low-noise casters. The subwoofer features a
threaded pole receptacle for a positive, wobble free connection to a
threaded speaker pole (included).
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.
