  • Inputs, Outputs and Mixing
    Combo XLR and 1/4-inch 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® (DMT) 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 over excursion. On-demand cooling fan and thermal limiting prevent overheated electronics.
