Know before you buy
The bipolar array uses drivers on both the front and back of the speaker to project sound in multiple directions. This creates a wider, more immersive soundstage that fills the room more effectively than traditional forward-firing speakers, giving your music and movies a greater sense of depth and realism.
Not necessarily. Each speaker features an integrated 10-inch powered subwoofer and dual passive radiators, which provide significant low-end output on their own. For most rooms, this setup delivers plenty of bass, though dedicated home theater enthusiasts may still choose to add a separate subwoofer for extreme low-frequency effects.
Yes, the DM70 is designed to be compatible with immersive audio formats. You can purchase optional height modules that integrate directly into the top of the cabinet to reflect sound off your ceiling, providing the overhead effects required for Dolby Atmos and DTS:X.
With a sensitivity of 90 dB and an impedance of 4 ohms, these speakers are relatively efficient, but they perform best with a quality amplifier that can handle a 4-ohm load. Ensure your receiver or amplifier is rated to handle 4-ohm speakers to get the best performance and avoid clipping.
The outrigger feet are designed for stability and include both spikes for carpeted surfaces and protective pads for hardwood or tile floors. This allows you to securely level the speakers on almost any surface while decoupling them from the floor to reduce unwanted vibrations.
Because the bipolar design relies on sound reflecting off the wall behind the speaker, you should ideally place them at least 6 to 12 inches away from the back wall. Experimenting with this distance will allow you to fine-tune the balance between the direct sound and the reflected sound to suit your room's acoustics.
