QSC K-SUB 1000W 2 x 12" Subwoofer
The QSC K Series is quite simply The New Standard in lightweight powered loudspeaker systems. For starters, each of the four models features an all new, Pat Quilter designed 1000 watt QSC Class D power module. Next, breaking from the traditional loudspeaker paradigm, every QSC K-SUB 1000W model is fitted with the identical 1.75" HF device (fullrange models) and woofers of the same high quality for unparalleled performance, regardless of speaker size.

Extensive DSP processing is employed throughout, providing levels of sonic
clarity and total output that defy the system's size and weight.
Premium-grade materials, advanced construction processes and multiple mounting
and suspension options allow for a wide range of live and installed
applications.
Combo XLR and 1/4" TRS inputs accept both Mic and Line Level input while a set
of RCA phono inputs (except KSub) allow additional connectivity to portable MP3
players, CD players and line-level mixers. Up to three audio sources can be
mixed internally and summed to a balanced output for "daisy-chaining" of
multiple units. Separate direct outputs are also provided on each channel for
additional output flexibility.
On-board switches provide preset EQ settings. The HF setting (fullrange models)
can be set to VOCAL BOOST for additional presence in the critical mid-frequency
area or FLAT for accurate reproduction of the incoming signal. The LF switch can
be set to NORM, DEEPâ„¢ for additional bass extension, or EXT SUB (fullrange
models) for use with an external subwoofer. The rear panel LED switch can be set
to POWER, illuminating the front-mounted LED when the unit is powered on, OFF
for applications where it is not desirable to illuminate the front LED, or LIMIT
which indicates to the system operator that the clip limiter circuit has been
engaged during operation.
Fullrange models are housed in rugged ABS enclosures with a professional
appearance that is at home in any application. ABS is a far more robust material
than conventional speaker plastics and offers an additional measure of sonic
clarity due to its internal rigidity. Ergonomic aluminum handles and a highly
protective steel grille complete the package for ease of transport and long term
durability.
The K Series fullrange models feature a unique Tilt-Directâ„¢ pole cup mounting
system. A simple turn of the dial engages a 7.5 degree downward tilt of the
speaker allowing acoustic energy to be kept on the audience and off reflective
surfaces for applications where maximum coverage from a high-positioned speaker
is desired. Integrated M10 suspension points allow for suspended applications
with a K SERIES M10 KIT (sold separately) or Yoke bracket (sold separately).
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
DMTâ„¢ (Directivity Matched Transition) provides for matched LF and HF coverage
across the entire listening area, eliminating unnatural "dead" or "hot"
frequency zones.
Intrinsic Correctionâ„¢, 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.
DEEPâ„¢ and excursion limiting allow for extended low-frequency response by
actively managing low-frequency transients without degradation of the underlying
signal or adjacent frequencies.
GuardRailâ„¢ protection, first introduced on our GX Series amplifiers protects
both the amplifier module and your performance from unnatural and destructive
clipping.
