Hi I’m selling this Bose SE-5 Acoustimass passive bass module in black. Features left and right speaker-level inputs and outputs with spring-clip terminals. Label specifies 100 watts IEC continuous power handling and 6-ohm nominal impedance. Works. Measures approximately 20” x 12.5” x 7”. Cabinet shows scratches, surface marks, and chipped edges and corners. Bass module only; satellite speakers and wiring are not included. Requires an external amplifier or receiver.
