The Beolab 4 loudspeaker by B&O includes built-in amplifier and proprietary acoustic technologies (B&O love their proprietary stuff). These are also active speakers, so the amplifier is encased in the cabinet. And because they're small, they're perfect for either a home theatre situation (I'd use them as rear speakers. Or, with their dedicated PC mode, you can hook up to your computer or MP3 player anytime to make them more portable. Placement options are also pretty diverse — and with the prices B&O charge, you better have options. Hang them from the ceiling, put them on the wall, floor or any table and you'll also have a choice of cloth covers in red, blue black and charcoal gray. Get them in December for $1,200 a pair.
