The QSC AD-S28Tw is a surface-mount subwoofer from the AcousticDesign Series, built to extend the low-frequency range of installed background and foreground systems. It uses dual 8-inch polypropylene woofers in a rugged marine-grade plywood enclosure that exceeds MIL-SPEC 810 environmental standards with an IP-X4 splash rating, making it well suited to demanding indoor and covered outdoor locations. An onboard 70V/100V transformer with multiple taps (plus 8-ohm bypass) and a defeatable 120 Hz low-pass filter simplify integration into distributed systems. This model is offered in black only.
