The Dymension™ DM30 flagship center channel speaker combines a five-driver array with an integrated subwoofer and 3XR-optimized bass radiators to deliver full-range performance with superior vocal clarity and maximum bass impact. It’s the ultimate centerpiece for immersive home theater and music systems.

Four 5.25" midrange woofers and a 1" aluminum oxide tweeter deliver ultra-clear vocals with uncanny realism. Add DM30's integrated 8” powered subwoofer and it’s full-range, immersive sound that draws you into the action every time.

An integrated 8” powered subwoofer delivers clean, detailed bass that perfectly blends with mids and highs, anchoring voices and effects with rich, full-range sound.

Introduced in our flagship Descend Series, 3XR™ Architecture combines a subwoofer and two passive radiators to produce huge, impactful bass that’s unrivaled in a center channel speaker. Get ready to experience low end you can feel.

Woofers feature Definitive’s Balanced Double Surround System™ (BDSS), which improves excursion and provides superior midrange detail. A Linear Response Waveguide extends off-axis dispersion for total sonic immersion.

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

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.

Dymension speakers fill the entire room with enveloping sound. They seem to vanish as you hone in on every voice and instrument—just like being there, live.

Whether you’re battling evil forces or exploring new universes, unlock the ultimate experience when you hear sonic details in dazzling new dimensionality.

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.

The DM30 features an acoustically transparent cloth wrap. As you dim the lights, it virtually disappears into your room—so you can focus on the movie, not your speakers.
