Introduction

The BM9S is designed according to the strict BM series specifications. With a 10" woofer and 200 Watts of power, and virtually minute dimensions, this sub is tailor-made to take care of even the most comprehensive challenges where space is scarce.

Being every bit as versatile as the rest of the BM series, BM9S 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.
