Designed by Ron Arad and Frances Pellisari for Austria’s Viteo, the Freewheeler produces high quality stereo sound indoors or out. The speaker measures in at about 22.8″ tall x 9.8″ wide, making it just about the same diameter as the tires on a Mazda MX-5 Miata (and about 2x as thick).

Just roll the Freewheeler around your house, and it’ll play your tunes remotely. Simply plug your audio source into the included transmitter, and a built-in FM receiver and rechargeable battery pack lets you wheel the mobile sound system up to 656 feet (200m) away from the base station.

A pair of coaxial speakers mounted inside the lacquered wood enclosure provide true stereo sound. Frequency response is 52 – 21,000 Hz, with a maximum output SPL of 112 dB. A single charge of the battery should give you about 8 hours of play time.

It all sounds really cool, no? Well here comes the bad part… The Freewheeler must be created solely for the uber wealthy. I’m hoping this price is a typo, but according to retailer MadeInDesign, the speaker sells for over $21,000 (USD), making it just about as expensive as that Miata I mentioned earlier, complete with four tires and a spare.
