Building on the success of our K Series, the KW Series represents the next evolutionary step in wood enclosure loudspeakers. QSC's system engineers have created the KW Series to feature all the groundbreaking electronic attributes of our popular K Series while at the same time designing a product that is both smaller and significantly lighter than previous wood enclosure models.
High Output: Like K Series, each of the four KW Series models features a QSC designed, 1000 watt (2 x 500) Class D power module.
Defined Coverage Area: Directivity Matched Transition (DMT) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural dead or hot frequency zones.
DSP: Extensive signal processing is employed throughout, providing levels of sonic clarity and total output that defy all expectations for a product in this category.
Connectivity: KW Series features a four-position mic / line gain switch that allows for connection of a wide variety of devices. Up to 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.
Remote Gain: Remote gain control capability is offered via a potentiometer (not included) connected to the on-board Phoenix-Style connector. In an installed application, multiple KW Series speakers can be daisy-chained for total gain control from a single remote pot. Auto-standby mode is engaged after 5 minutes of inactivity.
Premium-grade materials: KW Series is designed to withstand the rigors of professional use. Advanced construction processes, premium-grade Baltic birch cabinetry, ergonomic, cast aluminum handles, low-noise casters, and a highly protective steel grille provide for ease of transport and long term durability. Wobble free connection to a threaded speaker pole (included).
