QSC AD-S28Tw Dual 8" Bandpass Subwoofer

QSC AD-S28Tw Dual 8" Bandpass Subwoofer, 70/100V transformer with 8Ω bypass (Black or White)

The AcousticDesign Series of installation loudspeaker products from QSC expands with the new QSC -S28Tw surface mount subwoofer system. QSC -S28Tw is a dual8" bandpass subwoofer with 70/100V transformer with 8Ω bypass. The new QSC -S28Tw is designed to supplement audio systems by adding low-frequency extension, and is acoustically matched to the entire AD Series. It is able to take up to 700 watt peaks and rated for 250 watts continuous power handling, the AD-S28Tw is a great complement to any of the surface-mount and ceiling-mount AD Series models.

QSC -S28Tw dual 8" woofer is designed with polypropylene cones for protection in humid environments. The bandpass enclosure features two chambers. One chamber features a large port while the other one is completely sealed. The bandpass design is allowing for tight precise bass with extension down to 36 Hz. This highly efficient design is producing a 1W at 1m sensitivity of 94 dB SPL. The AD-S28Tw has a built-in passive low-pass filter set at 120 Hz.

The marine grade plywood enclosure is built to the highest standard to provide exceptional resistance to high humidity. The zinc-plated steel grille has a black foam backing, molded ABS endcaps and a rotatable logo. On the rear of the enclosure is the input cup with a hinged door to conceal the controls and input connections. Input and output nickel plated screw terminals accept wiring from 18 AWG (1.02 mm) to 12 AWG (2.053 mm). Two rotary switches can be found in the input cup. One switch selects between the 70V/100V transformer taps, while the other switch enables or disables the internal passive low-pass filter. The AD-S28Tw can be deployed in a number of ways. With the included rubber feet attached, the subwoofer can be floor or shelf-standing. Suspended installation is available with either the included forged-shoulder eyebolts and accessories or the included steel yoke.
