MacWorld Update: Griffin Technology today announced the unveiling of its new lineup of powered speaker systems.

Spearheading the line-up on the show floor is an iPod-ready wireless speaker system with powerful, crystal clear sound.

Griffin's Evolve is a speaker system with a flat charging base that holds your iPod in a Universal Dock. On either side are charging stations for two cube-shaped speakers, each housing its own long-lived Lithium-Ion battery pack. To charge these speakers, all you have to do is place them on the charging station -- nothing to plug in, nothing to unplug.

The Lithium-Ion batteries will give you up to 10 hours of music, and each speaker cube features its own on/off power switch and automatic sleep mode for power conservation.

Evolve's speaker enclosures are engineered for stellar sound, ease of use, and bang for the buck. The sound you get from this speaker system will knock your socks off -- and so will the sleek industrial design that will look great in any decor.

Evolve features a wireless range of more than 150 feet, allowing users to listen wirelessly, and control the sound wirelessly with the included remote.
