Another aesthetic problem: concert speakers. You pay big money to go to a concert, listen to great music, and stare at a bunch of wires and appliances.
Solution: stylized speaker stacks with no wires. They use charging mats, kinda like the ones you use for your iPhone, PSP, etc. The idea is that they are custom built to the consumer's preferences.
Here you have an industrial-look speaker stack, and a funky organic one.
