Dymension DM70

Anatomy of an Iconic Speaker

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.

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.

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.

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

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.
