The Dymension™ DM90 integrated height module attaches to Dymension DM80 and DM70 bipolar tower speakers to provide upward-firing drivers that make the towers Dolby Atmos-enabled. With DM90s attached to DM80 or DM70 speakers, you can create the Dolby Atmos-enabled and DTS:X speaker system of your dreams.
KEY BENEFITSPurpose-Built Add-On Modules
An upward-firing mid/bass woofer and tweeter project sound toward the ceiling where it reflects back to you, providing a sense of height that translates to a more immersive listening experience.
DM90 connects easily to Dymension™ DM80 or DM70 bipolar tower speakers. The speakers and the height module feature a snap-in connection system that makes electrical connections and secures the height module to the top of the speaker.
BDSS System and Linear Response Waveguide
DM90’s 5.25” mid/bass woofer features our patented Balanced Double Surround System™ technology. BDSS improves midrange driver excursion and provides a wide, uniform soundstage with seamless mid/bass integration. A Linear Response Waveguide™ extends and smooths off-axis dispersion for great sound everywhere in the room.
Aluminum Oxide Tweeters
DM90’s rigid, well-damped tweeter utilizes a new aluminum oxide design that provides smooth extended response with crisp transients and exceptional definition, for lifelike realism whether you’re immersed in a movie or your favorite tunes.
Consistent sound across Definitive Technology series gives you the flexibility to mix and match Dymension™, Dymension CI, and Mythos speakers to design your dream home theater and whole-home system.
