Manufacturer's Description from Dynaudio

True Bass

The 9S subwoofer is designed to complement LYD and other Dynaudio Pro studio monitors, including the classic BM range.


Studio-quality components and construction make the 9S, with its double front baffle and brand-new 9in long-throw driver, the ideal subwoofer for your mixing and mastering projects. We made it a priority to make the 9S compact while ensuring that you get the utmost sonic accuracy. In terms of size, it resembles the BM 9S II that it replaces, but when it comes to performance, it’s actually more comparable to the larger BM 14S II.



The 9S will expand any studio monitor setup regardless of whether you’re working in stereo or surround. Its massive yet tight low-end takes the burden off your monitors – letting them focus on delivering the frequency range above 50-150Hz, depending on how you set the crossover filter.


A long-throw driver ensures the necessary movement to reproduce super low-end frequencies all the way down to 22Hz in great detail. Running the show is a 300W Class D amplifier module that significantly outperforms the previous BM 9S II.



 ♦ 300-watt state-of-the-art Class D amplifier module

 ♦ 9in long-throw MSP woofer for accurate low-end frequency reproduction

 ♦ 22-175 Hz frequency range

 ♦ Sealed, black-vinyl cabinet

 ♦ 37mm front baffle

 ♦ Master/Slave feature for daisy-chaining multiple subwoofers

 ♦ Adjustable lowpass filter to set the perfect crossover frequency

 ♦ SAT output with defeatable highpass filter

About Manufacturer

The Vision A world where there is no difference between real / live sound and sound reproduced by a loudspeaker. A world where audio engineers, consumers, music-lovers and film viewers expects 100% accurate reproduction of sound - the perfect illusion with all the transparency, details and imaging we know from the real world. This is the vision of Dynaudio Acoustics - a world where you trust what you hear without even thinking about loudspeakers. The Mission Develop, innovate and manufacture state of the art monitors that can be trusted 100% by audio engineers and artists. Everything we do is centered at the artists that work with audio and demands transparent and accurate reproduction of sound - our customers. After all, it is the very same artists that in return give us productions and art that make it all worthwhile. We constantly challenge ourselves and innovate in search of further improvement and perfection of sound reproduction. Our customers Include some of the most demanding studios, engineers, producers and production environments throughout the world. We are proud of our customers and what they achieve. The Owl The great horned owl is known for its super hearing, sight for details, intelligence and precise judgement. Horned owls are active during night. They rely on and trust their ears 100% when navigating through the big woods searching for food. It is said that the great horned owl while in the air can hear small targets moving on the ground - they can also hear the exact distance and direction to the sound source. The ability to focus on, hear and judge the detail while working with the big picture is what makes working with audio an art. Engineers, like the great horned owl, must trust what they hear. Like the great horned owl, we believe that engineers deserve the freedom to navigate and judge the sound-scapes relying on their ears. That is the reason we have placed the Great Horned Owl in the centre of our Logo and that is the reason we build monitors that speak the truth - not more, not less.
