The QSC KW153 is a high-performance, 3-way active loudspeaker designed to deliver exceptional audio clarity and power for various professional applications. It features a robust 15-inch low-frequency cone transducer, a 6.5-inch mid-range cone transducer, and a 1.75-inch diaphragm compression driver, collectively providing a frequency response from 35 Hz to 18 kHz (-6 dB) and a peak SPL of 134 dB. The speaker is powered by a 1,000-watt Class D amplifier, distributing 500 watts each to the low-frequency and mid/high-frequency drivers. Its 75° conical DMT™ (Directivity Matched Transition) coverage ensures consistent sound dispersion across the listening area. Constructed with a rugged, texture-painted birch plywood enclosure and equipped with tour-grade 16-gauge steel grilles, the KW153 is built for durability. Additional features include an onboard mixer with versatile input options, extensive DSP with DEEP™ and Intrinsic Correction™ technologies, ergonomic handles, and M10 rigging points for suspended installations, making it a versatile choice for both portable and installed sound systems.
