Fully Balanced, Adjustable Bipolar Array
Bipolar driver arrays direct more sound in more directions than traditional speakers
for incredible depth-of-field and a truly enveloping listening experience. Bipolar effect
can be adjusted to optimize for room placement.

BDSS System and Linear Response Waveguide
DM80’s four 5.25" mid/bass woofers feature our patented BDSS technology. BDSS
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 Tweeters
DM80’s rigid, well-damped aluminum oxide tweeters provide smooth extended
response with crisp transients, pinpoint imaging, and exceptional definition, for
incredibly lifelike sound.

Built-In 12" Powered Subwoofer
An integrated 12" subwoofer, powered by an all-new, high-performance GaN FET
400W amplifier, delivers clean, detailed bass that perfectly blends with mids and
highs and feels consistent no matter where you sit. All-in-one design means simpler
setup and a streamlined footprint—no extra subs required.

3XR™ Architecture with Dual Bass Radiators
3XR Architecture—introduced in our critically acclaimed Descend Subwoofer Series—
combines a subwoofer and two passive radiators to produce huge, balanced bass in
any space, with less distortion than traditional ported designs. It’s low end you can
feel— everywhere in the room.

Patented Intelligent Bass Control
Sophisticated digital processing seamlessly blends subwoofer output with mids and
highs to provide powerful deep-bass performance without sacrificing midrange clarity.
Bass will never get in the way of dialogue and other critical soundtrack elements.

Consistent sound across other 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.

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