Advanced Five Driver Array

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

Built-In 8” Powered Subwoofer

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.

3XR Architecture with Dual Bass Radiators

3XR™ Architecture—introduced in our flagship Descend Series—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.

BDSS System and Linear Response Waveguide

The DM30’s midrange woofers feature Definitive’s Balanced Double Surround System™ (BDSS), which improves excursion and provides superior midrange detail. Our patented Linear Response Waveguide™ extends off-axis dispersion for total sonic immersion.

Patented Intelligent Bass Control

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.

Disappearing Design

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


Consistent sound across other Definitive Technology series gives you the flexibility to mix and match Dymension™, Dymension CI, and Mythos speakers to design your dream home theater and whole home system.
