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.
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.
