Following the successful launch of its powered K Series QSC have gone a step further with the introduction of the KW Series. Building on the same successful platform as the ABS-moulded K Series (which it is designed to complement), it has been engineered to produce the same performance but in a second generation wooden enclosure. The form factor is consequently more compact and lighter than previous birch enclosure designs.

Packaged into the new, second generation Baltic birch design is the same 1kW of Class D power modules (2 x 500W), 1.75-inch high output HF device (in the full-range models) and DSP featured in the K Series.

The KW Series comprises four models — the KW122 (12-inch, two-way multipurpose loudspeaker), KW152 (15-inch, two-way trapezoidal loudspeaker), KW153 (15-inch, three-way trapezoidal loudspeaker) and KW181 (18-inch subwoofer).

In addition to the 1kW of Class D power, the system incorporates DEEP and Intrinsic Correction as performance enhancers into the DSP, while DMT (Directivity Matched Transition) ensures uniform coverage across the entire sound field. In addition, the KW Series features GuardRail protection, first introduced on QSC’s GX Series amplifiers, which prevents the amplifier module from unnatural and destructive clipping, while the full-range models also include a four-position Mic/Line gain switch.

The construction of these birch enclosures has also been carefully conceived, with tour grade 16-gauge steel grilles, ergonomic handles, 35mm pole sockets with Tilt-Direct (on the KW122 and KW152 models). M10 rigging points enable suspended installation of the full-range models, while the KW122 can also function as a stage monitor.

In addition to the Class D amplification and DSP, the KW122 contains a 12-inch cone transducer and 1.75-inch diaphragm compression driver, with 50Hz-20kHz frequency range, maximum SPL (1 meter) of 131dB (peak) and nominal coverage of 75° axisymmetric; the KW152 contains a 15-inch cone transducer and 1.75-inch diaphragm compression driver, with 44Hz-20kHz frequency range, maximum SPL (1 meter) of 133dB (peak) and nominal coverage of 60° axisymmetric; KW153 3-way system contains a 15-inch cone transducer, 6.5-inch mid-range and 1.75-inch diaphragm compression driver, with 33Hz-20kHz frequency range, maximum SPL (1 meter) of 134dB (peak) and nominal coverage of 75° axisymmetric, and the KW181 subwoofer contains an 18-inch cone transducer, with 39Hz-145Hz frequency range and maximum SPL (1 meter) of 132dB (peak).

KW Series features a four-position mic / line gain switch that allows for connection of a wide variety of devices. Combo XLR and quarter-inch TRS inputs accept both mic and line level input while a set of RCA phono inputs (except KW181) allow additional connectivity to portable MP3 players, CD players and line-level mixers. 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.
