Full Sound, Slim Profile

The Dymension™ DM20 provides exceptional center channel definition to any immersive home theater system with a low-profile design that can be placed below your TV or be wall mounted in an LCR configuration. Its four long-throw woofers and aluminum oxide tweeter deliver dynamic, full-range sound with superior vocal clarity.


  • Advanced five-driver array
  • 4" long-throw midrange woofers
  • Aluminum oxide tweeter
  • Slim, wall-mountable design
  • Flexible use as a center channel or LCR speaker

Slim, Wall Mountable Design

DM20’s slim, low-profile design accommodates home theater cabinetry or can be wall-mounted easily. But don’t let its size fool you, the DM20 produces powerful, clear sound.

Advanced Five Driver Array

The DM20’s four 4" midrange woofers and 1" tweeter deliver dynamic, full-range sound that commands your attention and pulls you into the action.

Custom Aluminum Oxide Tweeter

The DM20’s rigid, well-damped tweeter provides smooth extended response with crisp transients and exceptional definition. You’ll notice clearer speech than ever before, along with a more precise sonic image.

Long-Throw Midrange Woofers

Midrange woofers feature composite polymer cones that produce superior midrange detail. Long-throw surrounds optimize driver excursion for improved low-end performance.


Consistent sound across 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.

Disappearing Design

The DM20 is wrapped in an acoustically transparent black cloth grille. As soon as you dim the lights, it virtually disappears into your room—so you can focus on the movie, not your speakers.
