CES 2013

If you want your floorstanding speakers to have Bluetooth, the Crystal Matrix Tower does it with a small module that plugs into the back and a separate transmitter with 30-pin, USB, and mini jacks. Also interesting is the way the half-dozen tweeters are divided into two groups of three, each group aimed outward at a slightly different angle, to ensure wide dispersion. Pricing is $3000/pair.
