Data Sheet

Building on the success of our K Series, the
KW Series represents the next evolutionary step
in wood enclosure loudspeakers. Our system
engineers have created the KW Series to feature
all the groundbreaking electronic attributes of
our popular K Series while at the same time
designing a product that is both smaller and
significantly lighter than previous wood
enclosure models.
High Output: Like K Series, each of the four
KW Series models features a QSC designed,
1000 watt (2 x 500) Class D power module.
And continuing in the K Series tradition, every
model is fitted with the identical high-output
1.75" HF device (full-range models) and woofers
of the same high quality design, regardless of
speaker size.
Defined Coverage Area: Directivity Matched
Transition (DMT™) provides for matched LF
and HF coverage across the entire listening
area, eliminating unnatural ”dead” or ”hot”
frequency zones.
DSP: Extensive signal processing is employed
throughout, providing levels of sonic clarity and
total output that defy all expectations for a
product in this category:
• Intrinsic Correction™, first featured in our
high-end line array products 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. 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.
Connectivity: KW Series features a four-position
mic / line gain switch that allows for connection
of a wide variety of devices. Combo XLR and
1/4" TRS inputs accept both mic and line
level input while a set of RCA phono inputs
(except KW181) 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.
Control: On-board switches provide preset EQ
settings. The HF setting (full-range 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, DEEP™ for
additional bass extension, or EXT SUB (full-range
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.
Tilt-Direct™: The KW122 and KW152 feature
a unique Tilt-Direct™ 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.
Remote Gain: Remote gain control capability
is offered via a potentiometer (not included)
connected to the on-board Phoenix-Style
connector. In an installed application, multiple
KW 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.
Premium-grade Materials: KW Series is
designed to withstand the rigors of professional
use. Advanced construction processes,
premium-grade Baltic birch cabinetry,
ergonomic, cast aluminum handles, low-noise
casters (KW181) and a highly protective steel
grille provide for ease of transport and long
term durability. Integrated M10 suspension
points allow for flown applications with a KW
M10 KIT (sold separately) and a threaded pole
receptacle (KW181) provides for a positive,
wobble free connection to a threaded speaker
pole (included).
