Rare and scarce Dynaudio BM9S II, fully functional.

The BM9S II is an active subwoofer that reflects the latest subwoofer technology, making it the perfect match for the BM Compact mkll/BM5 mkIll. Equipped with a 200W amplifier, it boasts a frequency response of 29Hz-250Hz, delivering rich bass reproduction that belies its compact size.

It features an LFE input that supports low-level signals and an LFE output terminal for linking multiple BM9S II units. It also includes input/output terminals for signals supplied to satellite speakers, along with a high-pass filter function, enabling the sophisticated construction of a surround monitoring system. This allows the low-frequency reproduction to be handled entirely by the BM9S II, dramatically enhancing the performance of your satellite speakers.
