Speaker wire is expensive if you buy it at retail, cheap if you just use a spool of electrical cable, but always, always an eyesore. Sure, you can pull it through the drywall, hide it behind some curtains -- or you can just go wireless. That's the option Cue Acoustics will enable with its PS1 bookshelf speakers, shipping this August. They're a high-end pair, each internally amplified and offering a 5-inch downward-firing woofer, 3.5-inch mid, and .75-inch tweeter, covering all the acoustic hotspots with fanfare. More important, though, is that each speaker can run with only one cable: power. Full details after the break.
