UGO wriets: "Decking your living room out with a premium sound system usually means having to tear through your walls to accommodate a mess of mounts and wires. That doesn't have to be the case if you opt for the Eos speaker system, which utilizes GigaWave technology to broadcast sound to remote speakers without the aid of wires. It has a base unit which acts as a docking station and transmitter that sends audio signals to up to four satellite speakers through walls, ceilings, and floors anywhere within a 150-foot range.
Setting the system up was as easy as the manual described. Once the base unit was hooked up and the iPod was docked, any additional speakers that were connected immediately started receiving the audio feed."
