Kef Muon Series - £70,000

Catering to the highest of the high-end in speakers will grab the attention of both consumers and designers, and KEF has contracted Ross Lovegrove, who designed such throw-aways as the Walkman and the iMac, to create this spendy new "Muon" series of speakers.
These curvy monsters are carved out of a six-foot block of solid aluminum using computer-aided manufacturing and take a week to create. The four-way, eight-speaker setups retail for £70,000 and only 100 pairs exist.
