QSC INTRODUCES NEW SURFACE MOUNT SUBWOOFER

ADS28Tw Dual eight-inch system is ideally suited for large or small applications

COSTA MESA, CA, February 9, 2009—As the latest addition to QSC's AcousticDesign Series, the model AD-S28Tw surface mount subwoofer is acoustically matched to all other offerings within the AD Series. Shipped with a spec sheet revealing a continuous power handling capacity of 250 watts and capabilities for managing up to 700 watt peaks, the new subwoofer has a 70/100 volt multi-tap transformer with eight ohm bypass, frequency response of 42 Hz-165 Hz, and sensitivity of 94 dB (1W/1m).

Central to the AD-S28Tw's high performance prowess are a pair of eight-inch woofers outfitted with polypropylene cones for added protection in humid environments. The loudspeaker's bandpass enclosure incorporates a pair of chambers: One that is completely sealed, and another with a large port. Giving added precision to low frequency extension down to 36 Hz, the highly efficient design is further complemented by an onboard low-pass filter set at 120 Hz.

Featuring marine-grade plywood construction, a zinc-plated steel grille with a black foam backing, molded ABS endcaps, and a rotatable logo, the AD-S28Tw enclosure has additionally been fitted with a recessed rear input panel covered by a hinged door. Nickel-plated input and output terminals found on the subwoofer accept wiring ranging from 18 AWG to 12 AWG. One switch selects between the 70/100V transformer taps, while another enables or disables the passive low-pass filter.

Adding to the versatility of the AD-S28Tw, attached rubber feet allow the device to be used on either the floor or a shelf. Forged-shoulder eyebolts, a steel yoke, and all related hardware are additionally included with each loudspeaker to offer options for suspended installation.
