QSC KW153 Active 15-inch 3-way 2000 Watts Loud Speaker

Features

• 15-inch woofer; 6.5-inch midrange woofer; 1.75-inch diaphragm compression driver

• 75° conical DMT coverage

• Maximum SPL 134 dB peak

• 1000-watt Class D power modules in all models (2 × 500 W continuous)

• Onboard mixer with two combo XLR and ¼⁻ᶦⁿᶜʰ inputs, and stereo RCA inputs, (three audio input sources); two direct channel outputs and single summed balanced output

• Extensive DSP featuring DEEP™ and Intrinsic Correction™ enhances system performance

• DMT™ (Directivity Matched Transition) ensures uniform coverage across the entire sound field

• Rugged, texture-painted birch enclosures

• Four-position Mic/Line gain

• Tour-grade 16 gauge steel grilles

• Comfortable ergonomic handles

• 35 mm standard (non-tilt) pole socket

• M10 rigging points for suspended installation

• 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 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.
