KEY BENEFITS
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. The bipolar effect
can be adjusted to optimize for room placement.
BDSS System and Linear Response Waveguide
DM70’s four 5.25” mid/bass woofers feature our patented Balanced Double Surround
System™ technology (BDSS). 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
DM70’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 10” Powered Subwoofer
An integrated 10” subwoofer, powered by an all-new, high-performance Class D 180W
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.
Timbre-Matched
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, this DM90 Atmos-certified and DTS:X-compatible height module
connects to the top of the DM70 to extend sound above you, for total sonic immersion
with hyper-realistic overhead effects.
