KEY BENEFITS

Fully Balanced, Adjustable Bipolar Array
Our bipolar driver arrays direct more sound in more directions than traditional
speakers for incredible depth-of-field and a truly enveloping listening experience.
The bipolar effect can be adjusted to optimize for room placement.
Long-Throw Midrange Woofers
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.
Aluminum Oxide Tweeters
The DM40’s rigid, well-damped tweeters utilize a new aluminum oxide design to
provide smooth, extended response with crisp transients and exceptional definition.
Pinpoint-precise imaging imparts lifelike realism, whether you’re immersed in a movie
or your favorite tunes.
Ported Enclosure with Column Resonance Control
Tuned cabinet features acoustically optimized chambers for improved bass extension
and midrange clarity.

so it looks as good as it sounds.

speakers on virtually any floor surface providing acoustic isolation and stability.
