KW Series Features

Inputs, Outputs and Mixing
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. As many as 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. 


DEEP™
Sophisticated digital signal processing provides greater low-frequency extension while precisely protecting the woofer from over-excursion. 

DMT
Directivity Matched Transition matches the HF coverage angle to the natural coverage angle of the woofer for uniform frequency response over the entire coverage area. 

Axisymmetric Wave Guide
The axisymmetric wave guide eliminates the phase distortions of typical asymmetric horns for more natural reproduction. 

1000 Watts
The same state-of-the-art, light-weight Class D amplifier module powers all the K and KW Series models.

EQ Modes
Optimize for a specific application with the simple flip of a switch. 

Energy Management
Automatic standby mode conserves energy and extends the life of the loudspeaker. 

LED Operation
Switch selectable: On (power indicator) / off (dark) / limit (limiter indication) 

Remote Control
Easy-to-use remote gain control is ideal for installed applications. 

Pro Appearance
Sleek lines and a full grille for a more professional look than other molded loudspeakers. 

Locking IEC Power Cable
Help prevent unexpected interruptions. 

Connectivity
Mic/line and RCA inputs along with onboard mixing controls allow greater flexibility. 

Tilt-Direct™ Pole Mount
A simple turn of the dial is all it takes to alter the vertical directivity by 7.5 degrees. 

Suspension and Mounting
With integrated threaded inserts, KW Series is equally at home in mounted or flown applications. 

Threaded Pole
The KW181 subwoofer comes with a threaded pole for a snug, safe fit. 

Intrinsic Correction
An exclusive QSC process that applies extensive acoustic measurements to noticeably improve audio quality. 

Class D
Higher efficiency produces less heat and more sonic performance with lower overall current draw. 

Protections
QSC's Guardrail™ technology protect your loudspeakers from overexcursion. On-demand cooling fan and thermal limiting prevent overheated electronics.
