The Outline AUX Level speaker looks to be a high-end loudspeaker designed to compliment large flat-panel TVs. Sounds pretty good, if unexciting, until you see how they decorate the thing.
The Muscinelli Edition, which costs $500 more than the boring other editions, was designed "using fireworks and paint." Yes, they took a high-end speaker and exploded paint all over it. If that isn't worth an extra $500, I don't know what is.
