This sleek, attractive, compact subwoofer features a down-firing, long-throw 200 mm (8-inch) driver which delivers 115 dB (peak) of clean, powerful bass down to 40 Hz. The built-in low-pass crossover features a dual-slope filter which begins with a gentle slope at the crossover frequency and transitions to a steeper slope at higher frequencies), creating a balanced subwoofer transition regardless of whether the speaker is driven from a full-range or a dedicated subwoofer amplifier channel. The premium-grade dedicated-subwoofer-band multi-tap transformer (and tap selector with 8Ω bypass) allows the Control 89MS to be used in 70V and 100V distributed systems or driven directly at low impedance, for maximum versatility.
The Control 89MS is IP56-rated to withstand the elements, with a tough polyethylene enclosure and a fully-sealed center wiring chamber. The enclosure color extends throughout the cabinet, maintaining color even when scraped or scratched. All external hardware is stainless steel, and the powder-coated stainless steel grille resists rusting.
