About Definitive Technology Dymension DM90

Dymension DM90 Integrated Height Module - Seamless Overhead Sound
The Dymension DM90 height module attaches to Dymension DM80 and DM70 bipolar tower speakers to provide overhead sound in immersive Dolby Atmos and DTS:X systems.

• Amazing Overhead Audio: Upward-firing drivers bring immersive Dolby Atmos and DTS:X soundtracks to life
• Crystal Clear Highs: An aluminum oxide tweeter delivers crisp, sparkling highs that reflect throughout the room
• Natural, Impactful Sound: A BDSS mid/bass woofer provides lifelike, natural midrange with amazing 3D spatiality

Total Sonic Immersion

Seamlessly Integrated 3D Sound
The DM90 integrated height module attaches to Dymension DM80 and DM70 bipolar tower speakers to provide upward-firing drivers that make the towers Dolby Atmos and DTS:X-enabled. With DM90s attached to DM80 or DM70 speakers, you can create the immersive sound system of your dreams.

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 Tweeter for crystal clear highs
A new driver design provides smooth extended response with crisp transients, exceptional definition, and pinpoint-precise imaging, for incredible clarity and lifelike realism.

The Ultimate Atmos Experience for immersive sound that pulls you inside the action
Bring the thrills of the movie-theater experience home with stunning sound enveloping you from every angle, transporting you inside every scene and song.
