Up for sale is a classic Acoustic Research S108PS powered subwoofer. Known for its musicality and tight bass response, this 8-inch down-firing sub is a fantastic addition to any home theater or 2-channel stereo setup. Unlike many modern entry-level subs, this unit was Made in Canada and built with a heavy-duty MDF cabinet for superior resonance control. Powerful Performance: Features a 100W RMS internal amplifier paired with a high-excursion 8 laminated paper cone woofer. Down-Firing Design: The downward-firing driver and port utilize the floor to load the bass, providing deep, room-filling sound from a compact footprint. Versatile Connectivity: Includes both Line-Level (RCA) inputs for modern receivers and Speaker-Level inputs/outputs (spring clips) for older vintage gear without a dedicated sub-out. Precision Control: Rear panel features adjustable crossover frequency (50Hz – 150Hz), volume/level control, and an Auto-On/Off power mode. Driver: 8 Woofer with Rubber Surround. Power: 100 Watts RMS. Frequency Response: 30Hz – 150Hz. Impedance: 8 Ohms. Dimensions: 13.5″ x 10.25″ x 13.5. Weight: 26 lbs. Tested & Functional: Fully tested; the amplifier is strong, and the driver surround is in excellent shape (no rot). This item is heavy and will be professionally packed with extra padding to ensure safe arrival.
