QSC KW153 Active 3 Way PA Speaker, 1000 Watt

Full Description

High output

Like K Series, each of the four KW Series models features a QSC designed, 1000 watt (2 x 500 W continuous) 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

Consistent sound for your entire audience. QSC's Directivity Matched Transition technology matches the natural high-frequency coverage angle of the KW153's woofer with that of the compression driver at the crossover frequency. This smooth transition means no more lost mids at the edges of the speaker's dispersion angle. With this balanced coverage, the listening area in front of your speakers is filled with the full frequency spectrum of your music, so everyone can experience the sound to its full potential.

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.

Extensive DSP enhances system performance

• DMT™ (Directivity Matched Transition) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones.
• 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 band pass 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 protects both the amplifier module and your performance from unnatural and destructive clipping.
