Know before you buy
Bipolar speakers emit sound from both the front and back of the cabinet. This design reflects sound off your walls to create a much wider, more immersive soundstage that makes your room feel larger than it is.
No, the 8-inch subwoofer is internally powered, meaning it has its own dedicated amplifier built into the speaker. You only need to connect your receiver to the speaker's input to handle the bass frequencies.
The DM40 is designed with a slim profile specifically to minimize its footprint. While exact dimensions vary by placement, its narrow design allows it to tuck into corners or alongside furniture much more easily than traditional, bulky tower speakers.
They are highly versatile and excel at both. The bipolar dispersion creates the expansive, cinematic atmosphere needed for movies, while the integrated powered subwoofer provides the punch and clarity required for high-fidelity music listening.
For the best results, you should avoid placing them directly against a wall. Leaving a little space behind the speakers allows the rear-firing drivers to reflect sound properly, which is essential for achieving that signature wide soundstage.
