Fully Balanced, Adjustable Bipolar Array

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.

BDSS System and Linear Response Waveguide

DM60’s four 4.5” mid/bass woofers feature Definitive's patented BDSS technology. BDSS improves midrange driver excursion and provides a wide, uniform soundstage with seamless mid/bass integration. A Linear Response Waveguide™ extends and smooths off-axis dispersion for great sound everywhere in the room.

Aluminum Oxide Tweeters

DM60’s rigid, well-damped aluminum oxide tweeters provide smooth extended response with crisp transients, pinpoint imaging, and exceptional definition, for incredibly lifelike sound.

Built-In 8” Powered Subwoofer

An integrated 8” subwoofer, powered by an all-new, high-performance Class D 180W amplifier, delivers clean, detailed bass that perfectly blends with mids and highs and feels consistent no matter where you sit. All-in-one design means simpler setup and a streamlined footprint—no extra subs required.

3XR Architecture with Dual Bass Radiators

3XR™ Architecture—introduced in our critically acclaimed Descend Subwoofer Series—combines a subwoofer and two passive radiators to produce huge, balanced bass in any space, with less distortion than traditional ported designs. It’s low end you can feel—everywhere in the room.

Patented Intelligent Bass Control

Sophisticated digital processing seamlessly blends subwoofer output with mids and highs to provide powerful deep-bass performance without sacrificing midrange clarity. Bass will never get in the way of dialogue and other critical soundtrack elements.


Consistent sound across other 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.

These speakers are magic
My first pair of home theater speakers were the Definitive BP8's with a C1 center some 26 years ago. Their open and engaging sound drew me in at a store demo, and they gave me years of happy listening. Since then I have had mainly Definitive offerings-direct radiating like the DefTech Mythos, and more recently the Demands which are also amazing. With the re-imagining of the bipolar line, it was time to come full circle. Suffice to say these are so far above and beyond my old BP8's it's not even any kind of contest. If you love movies, and the feeling that you are in them, you will get absolutely drawn in with these speakers. The sound stage is huge, but not forward or fatiguing. The midrange vocal clarity and character are clear and natural, and make me want to listen to more and different music just to see how it will present, which for me is when I know i'm having fun with my gear. As for the bass, well, it is seriously awesome. It is musical, clean, and feels effortless and free of any discernible distortion. It is powerful enough that in my apartment living I do not need an external subwoofer. Seriously, these onboard subs are amazing, when watching Guardians of the Galaxy 2 with the sub at 8 out of 31 clicks on the sub dial, my large living room space was filled with deep powerful bass during space ship fight scenes. And the new internal crossover does an amazing job of blending the bass with the midrange and high notes, everything is just presented so well it's just incredible. I could go on but in short these DM60's make movies come alive, and make music 3 dimensional and engaging. While I do wish I could remove the sock to see the drivers, it is a very clean look, and I'm especially fond of the new wrap around metal detail with the D in the center-I think this was a very classy touch and great design decision. My wife is a retired fashion designer, and she really likes the clean look of these speakers. I highly recommend these speakers, and the DM30 center is mind blowing, if you can swing it too it deserves a serious look. For reference I am using a Marantz SR5015 with Emotive amps to all 7 Definitive speakers, DM60's, DM30 center, BP9080 surrounds as well as a pair of Demand D15 surrounds. Thank you Definitive for making these, I absolutely love them!
