What is the best wireless speaker system?

Speakers need power. This means power comes from an amplifier and is delivered by speaker cables, or the speakers have a circuit inside which includes a wireless receiver and an amplifier. This in turn means each speaker needs more power than a conventional speaker, which in turn means either battery power or mains power. The louder you want to play the system the more power is required too.

Making speakers with wireless receivers and amplifier circuits and some sort of power source built in to each one is very expensive compared to simple and cheap-to-produce conventional PC speakers. It also makes for larger speakers. Most people don't appreciate why the speakers have to be larger and way more expensive, so wireless is a nice idea but often considered too expensive for "just some PC speakers".

There are some half-way-house solutions: The Rocketfish™ - Universal Wireless Rear Speaker Kit for example. http://www.bestbuy.com/site/rocketfish-universal-w... As long at your speakers have an impedance of 4-16 Ohms then this will help get rid of the cables from the front of the room going to the back. The problem for PC speaker users is that those little rear speakers are often 2-3 Ohm or not even rated. Using low Ohms speakers with a box or amp designed for higher Ohms is a bad idea.

Except that the rear speakers aren't wireless. The sub is wireless, sure. But the rear speakers have to be plugged in to the sub to work. So you still have speaker wires.
