Highlights & Key Technologies
BDSS & Linear Response Waveguide
DM90’s 5.25" mid/bass woofer features our patented Balanced Double Surround System technology, which improves midrange driver excursion and provides a wide, uniform soundstage with seamless bass/mid integration. A Linear Response Waveguide™ extends and smooths off-axis dispersion for great sound everywhere in the room.
Aluminum Oxide Tweeter
A new driver design provides smooth extended response with crisp transients, exceptional definition, and pinpoint-precise imaging for incredible clarity and lifelike realism.
Integrated Height Module Option
The DM90 Atmos-certified and DTS:X-compatible height module is an upward-firing mid/bass woofer and tweeter that projects sound toward the ceiling where it reflected back to you, providing a sense of height that translates to a more immersive listening experience. 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.
