A concert tuned to your liking! No matter what genres you love, your ears will thank you when listening through the Definitive Technology DM80s. These towers deliver a powerful, immersive soundstage that can go toe-to-toe with bespoke speakers costing far more. Don’t get me wrong these aren’t a budget buy but for their class, they absolutely hold their own. Two-channel listening is elevated with crystal-clear clarity, rich presence, and a surprisingly deep low end. Live recordings come through with stunning separation, letting you feel every note as if you were right there in the studio. I’ve got the rear-firing speakers dialed back -6 dB, simply because my listening space isn’t large enough to pull the towers further from the wall. They still produce incredibly balanced sound. Currently, I’m running them on an older Denon AVR-X1300W rated at 80W per channel at 8 ohms, but since the DM80s are 4-ohm speakers, I’m realistically pushing closer over 120W per channel. These towers can easily handle much more, so I plan to upgrade to a dedicated high-end 2-channel receiver and power amp to unlock their full dynamic range. That said, it doesn’t take much to get them to reference levels and they do it effortlessly. As they stand now, these two speakers alone can fill my 3,500 sq. ft. home and still have enough power to disturb the neighbors, even without being centralized in the house. I would like to see custom finishes options to make them more appealing to living room esthetics.

Wonderful speaker. No need for external subwoofers as they have 12 inch powered woofers. But wait till they’re on sale.
