Know before you buy
The DM90 is specifically engineered to integrate with the Definitive Technology Dymension DM80 and DM70 bipolar tower speakers.
The module features a plug-and-play snap-in connection that sits securely on top of the DM80 or DM70 towers, making installation straightforward without the need for complex mounting hardware.

Yes, the DM90 is timbre-matched to the rest of the Dymension series. This ensures a consistent, seamless audio transition as sound effects move across your room.
The DM90 is designed to handle object-based surround sound formats, specifically Dolby Atmos and DTS:X, by reflecting sound off your ceiling to create an immersive 3D audio experience.
Balanced Double Surround System (BDSS) technology allows the driver to produce a more lifelike midrange and greater excursion, resulting in clearer, more detailed sound compared to standard drivers.
