Anatomy of an Iconic Speaker

The Dymension DM80 fills your home theater with dynamic, expansive sound. Crystal clear highs, incredible depth-of-field, and thunderous bass envelop you whether you’re enjoying the latest blockbuster or your favorite songs. Innovations include aluminum oxide tweeters, an adjustable Balanced Double Surround System (BDSS) bipolar array, an integrated powered subwoofer with 3XR Architecture, and a cutting-edge GaN FET amplifier.


Fully Balanced, Adjustable Bipolar Array for a spacious, immersive soundstage

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


BDSS System and Linear Response Waveguide for smooth midrange and lifelike imaging

Our 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.


Built-In 12" Powered Subwoofer for thunderous bass

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.


Aluminum Oxide Tweeters for crystal clear highs

New driver designs provide smooth extended response with crisp transients, exceptional definition, and pinpoint-precise imaging, for incredible clarity and lifelike realism.


3XR Architecture with Dual Passive Radiators for seamless, balanced bass

3XR Architecture combines a subwoofer and two passive radiators to produce huge, balanced bass that you can feel, with less distortion than traditional ported designs.

DM90 Integrated Height Module Option for unforgettable Atmos experiences

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 hyperrealistic overhead effects.


Patented Intelligent Bass Control for precise low-end tuning

With the DM80, bass will never get in the way of dialogue and other critical soundtrack elements. Sophisticated digital processing blends subwoofer output with mids and highs to provide powerful deep-bass performance without sacrificing midrange clarity.
