Dynaudio 9S

The 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.


The Dynaudio 9S is an active studio subwoofer designed to extend the frequency response of your system all the way down to 22Hz.

The Dynaudio 9S uses Dynaudio’s proprietary MSP 9.5” long-throw woofer and unique double front baffle, housed in a stylish sealed-box design and powered by a 300-Watt Class D amplifier.

The 9.5” long throw woofer has been carefully designed for ultra-accurate sound reproduction of the low-end and is the ideal complement to Dynaudio’s BM and Lyd series of studio monitors. Combined with the carefully designed 300W Class D amplifier, it provides a powerful and tight low-end required for mixing and mastering.

Using the latest technology and components of the highest order, the 9S subwoofer delivers one of the most accurate and detailed Low frequency reproduction available. It also helps alleviate the pressure from your nearfield monitors and focus their sound on the midrange and highs. Its adjustable lowpass filter lets you adjust the perfect crossover frequency to tune your system.

At the back of the subwoofer are SAT outputs with a defeatable high-pass filter for additional flexibility and Master/Slave inputs to let you daisy chain several subwoofers together.
