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.
