Bose in an event this afternoon upgraded the SoundDock line with a new, particularly high-end model. The SoundDock 10 adds a dedicated subwoofer to reproduce the low end and has two large transducers that borrow the same technology as found in the Wave radio to project upper- and mid-range frequencies. Fresh for any Bose system is a completely interchangeable dock: it can not only accommodate different iPhones and iPods but can fit an optional $150 Bluetooth receiver for wireless stereo or, in the future, recognize non-Apple players.

The system has GSM shielding to prevent the "buzz" interference of a nearby phone and a remote to steer docked equipment from a distance. Bose plans for the SoundDock 10 to reach stores on the 21st and is pricing it well above the SoundDock II at $600.
