Anatomy of an Iconic Speaker

Bipolar driver arrays direct more sound in more directions than traditional speakers, for incredible depth-of-field and a truly enveloping listening experience. Adjustable to optimize for room placement.

DM40’s four 4.5" woofers feature composite polymer cones that produce superior midrange detail. Long-throw surrounds optimize driver excursion for improved low-end performance.

A tuned cabinet features acoustically optimized chambers for improved bass extension and midrange clarity.

New driver designs provide smooth extended response with crisp transients, exceptional definition, and pinpoint-precise imaging, for incredible clarity and lifelike realism.

The DM40’s slim footprint makes it easy to integrate into virtually any room setting. And, it looks as good as it sounds.
