Blaupunkt Velocity 2Go

The Blaupunkt Velocity 2Go ($TBA) makes the in-car subwoofer sensible again by functioning as a dedicated subwoofer when it's docked in the rear of the car, and as a portable boombox when you arrive at your destination. Features include RMS power of 80 Watts, two woofers, two tweeters (for boombox use), auxiliary input, and aluminum and MDF construction.
