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.

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.

Bring the thrills of the movie-theater experience home with stunning sound enveloping you from every angle, transporting you inside every scene and song.

Get swept away by the action onscreen as you’re enveloped in a deep, defined soundstage. From a whisper to a roar, experience it all in striking realism.

Available separately, a DM90 Atmos-certified and DTS:X-compatible height module connects to the top of the DM70 to extend sound above you for total sonic immersion and hyper-realistic overhead effects.

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

Consistent sound across other Definitive Technology series gives you the flexibility to mix and match Dymension™ and all Definitive Technology in-wall and in-ceiling speakers to design your dream home theater and whole-home system.

Included cabinet foot spikes and pads provide the ideal way to place and level DM70 speakers on virtually any floor surface, providing acoustic isolation and stability.
