Add-On Modules for Dolby Atmos and DTS:X 3D overhead audio

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.

Plug-and-Play Integration for easy, quick, secure installation

An easy snap-in connection system makes electrical connections and secures the height module to the top of Dymension DM80 or DM70 bipolar tower speakers.

BDSS System and Linear Response Waveguide for smooth midrange and lifelike imaging

Patented Balanced Double Surround System (BDSS) technology improves the midrange and provides a uniform soundstage with seamless bass and mid integration. A Linear Response Waveguide extends and smooths off-axis dispersion for great sound everywhere in the room.

Aluminum Oxide Tweeters for crystal clear highs

New driver designs provide smooth extended response with crisp transients, exceptional definition, and pinpoint-precise imaging, for incredible clarity and lifelike realism.

DM90 Integrated Height Module Option for unforgettable Atmos experiences

Available separately, a DM90 Atmos-certified and DTS:X-compatible height module connects to the top of the DM70 or DM80 to extend sound above you for total sonic immersion and hyper-realistic overhead effects.
