- Fully balanced bipolar driver array for truly enveloping sound
- Acoustically optimized ported enclosure for smooth bass and clear midrange
The Definitive Technology Dymension DM40 Slim Tower Speaker features custom aluminum oxide tweeters for explicit voice, four 4.5" midrange woofers with composite polymer cones to produce better midrange detail, and long-throw surrounds for low-end performance. A slim and acoustically tuned cabinet allows the speaker to fit into any room setting and deliver impressive performance. Fully balanced bipolar arrays of DM40 are adjusted to optimize for room placement and hold a rear-array attenuation switch for near-wall placement.
Pair this speaker with the DM20 Slim Center Channel Speaker and DM95 on-wall speakers (sold separately) to build an ultimate surround setup and deliver dynamic sound. Be it onscreen movie drama, melodies of your favorite singers, or hearing the sonic details while gaming, this high-performing speaker envelops you from every angle and transports you inside every scene and song. The consistent sound across Definitive Technology gives you the flexibility to mix and match Dymension, Dymension CI, and Mythos speakers, which can be voice-matched to design a complete home system.
