If you've got a lot of cash to burn, and need some new speakers, then this Freewheeler speaker may be just what you're looking for. The wireless speaker can operate 656-feet from its base station and has an FM receiver built-in. Once charge of the speaker will keep you rocking for up to 8 hours, and one speaker will cost you $21,000.

I have the perfect space for one of these on my back porch. Anyone want to buy me one?
