The D5XM, due in January for about $200, at first looks like simply a more stylish upgrade to the current D5x model. But the new D5XM has a twist: It builds a home theater for you. First comes the wireless capability that allows up to three units to communicate with each other and with a matching subwoofer over their own wireless network using the 5.4-gigahertz frequency. In “party mode” each speaker simply blasts the same thing to cover a larger area. But the speakers can also be set up as a home theater with left, right and center audio channels, plus rumbling from the subwoofer.

Another neat trick is a bit esoteric but very handy for people serious about audio. An audiophile can calibrate the system; adjusting for the shape of the room, equalizing the loudness of each speaker and other adjustments; using a simple app.
