The BM 9S subwoofer is intended to operate with the BM series monitors, more specifically, the BM 5A monitor. It is extremely well-suited for that extra punch to the bottom in setups where space is limited. The BM 9S delivers a clear, crispy and surprisingly powerful punch when you take its almost diminutive size into account. The BM 9S will complement stereo and multichannel monitoring equally well and when daisy-chaining of subwoofers is needed, it sports a low level LFE input/output.


For significant control and enhancement of the general performance, the BM 9S is a closed cabinet type. This creates an internal pressure by which the woofer gains a considerable amount of precision when it comes to the reproduction of low frequent signals. This precision is easily audible and it augments the feeling of reality that the listener experiences.


Being every bit as versatile as the rest of the BM series, BM 9S is a very competent partner for smaller stereo and multichannel setups, giving a very powerful system for even the most demanding users across the globe. The Auto On/Off function, provides a minimized idle energy usage by shutting off after minutes of no input signal. The auto sensing circuit enables BM9S to automatically come to life when input signal is detected.

The satellite filters that this sub sports, provides high-pass filtering of the monitor source signal allowing 60Hz or 80Hz corner frequencies. This is a huge advantage for the monitor performance, as the satellites do not need to deal with power consuming lower frequencies. This leaves all the satellite power to greatly accelerate performance and precision.

The BM 9S is very suitable for the following production environments: Post Production, Music Recording and Mixing, Film Editing (smaller rooms), DVD authoring and Mastering, Multichannel Production (Audio or Audio for pictures), Broadcast, Edit suites and OB vans.
