Oh the geeky have the coolest things. Fuck your 'plasma' TVs. I want plasma speakers.
The speakers use a plasma arc to create compression waves instead of the traditionally boring magnets and cones. The pitch is altered by the constantly shifting intensity of the plasma arc (the creator puts the frequency response range at 200Hz to 12kHz, and the speaker runs at 50W).

And just for fun, because bigger is better for the visuals and music alone, two tesla coils in synch and hooked up to a guys laptop. The kicker? They play at over 110 decibels. You know they're in some field somewhere scaring the cows:
