Large Bipolar Tower Speaker with Built-In 10" Powered Subwoofer
Spacious, Immersive Soundstage
Anatomy of an Iconic Speaker
The Dymension DM70 fills your home theater with larger-than-life sound. Crystal clear highs, incredible depth-of-field, and thunderous bass envelop you, whether you’re enjoying the latest blockbuster film or your favorite songs. Innovations include aluminum oxide tweeters, an adjustable BDSS bipolar array, and an integrated powered subwoofer with 3XR technology.
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 10" Powered Subwoofer for thunderous bass
An integrated 10” subwoofer, powered by an all-new, high-performance Class D 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.
