## Description

Level up your home theater audio with the Definitive Technology Dymension DM40 Slim Tower Speaker - a bipolar floorstanding speaker with a slim cabinet to fit into any room setting and delivers impressive performance in any home stereo system. DM40's fully balanced bipolar arrays are adjusted to optimize for room placement and hold a rear-array attenuation switch for near-wall placement. This speaker features four 4.5" long-throw midrange woofers that use composite polymer cones to produce better midrange detail and long-throw surrounds to optimize driver excursion for improved low-end performance. It's custom aluminum oxide tweeters for explicit voice provide a smooth extended response with crisp transients and exceptional definition. While the slim cabinet design integrates DM40 in virtually any room setting, the tuned cabinet improves bass extension and midrange clarity with the acoustically optimized chambers. Be it an onscreen movie drama or hearing the sonic details while gaming, this tower speaker always performs to the best of its caliber. 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.

Review: Buy them - These speakers are simply amazing. I had a 10” Definitive Technology subwoofer that I was going to hook up to my surround sound system, but it broke. After hooking up these two speakers, I don’t even need the 10” subwoofer. Each tower has a 180 amp 10” woofer integrated into them lol It would be overpowering for my whole system. My couch rattles. I added the Dolby Atmos DM90’s, as well a DM20 Center and the system rocks.
Review: definitive has finally lived up to its name - i had a pair of 7004 and i always thought i had a nice system. but man these m60 with a smaller woofer is the bomb. and i got a great price merry xmas to me
