The Perfect Sub For Your BM 5As!

The Dynaudio BM 9S subwoofer is intended to operate with the BM series monitors, more specifically, the Dynaudio BM 5A monitor. It is extremely well-suited for that extra punch to the bottom in setups where space is limited. The Dynaudio BM 9S delivers a clear, crispy and surprisingly powerful punch when you take its almost diminutive size into account. The Dynaudio 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.

Dynaudio BM 9S at a Glance:
  • Closed cabinet for a tight low-end punch.
  • The perfect size, especially when space is scarce.
  • Smart filters that will enhance the performance of your satellites.


Tight, Low-End Punch!
For significant control and enhancement of the general performance, the Dynaudio 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.

The Perfect Addition to Your BM 5A System!
The Dynaudio BM 9S 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, Dynaudio 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.

Get More From Your Satellites
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.

  • 10" woofer.
  • Phase adjustment in 0° / 180°.
  • Auto on/off, power LED.
