Speaker creator Altec-Lansing on Wednesday released the inMotion iMV712, a new speaker dock for the iPod that transforms into a small-scale home theater. Owners of the fifth-generation Apple music player can play videos on a large, 8.5-inch LCD embedded in the front of the system. Any Dock Connector iPod can take advantage of an enhanced sound stage, says the company. A four-inch subwoofer enhances the bass reponse compared to most speaker docks; the three-inch satellites also use Altec-Lansing's Sound Field Expander technology to widen the typically narrow stereo effect of all-in-one units.

The iMV712 is also more accommodating to third-party devices with both a minijack input for audio and RCA input for both audio and video from DVD players or similar sources. A cradle holds more portable devices separately from the iPod dock.

Altec-Lansing expects to ship the new inMotion hybrid dock later this month bundled with a wireless remote and should sell at a price of $350.
