Every portable computer, from the brawniest desktop replacement to the tiniest netbook, has one thing in common: terrible speakers. There’s no shortage of powered speaker systems on the market—some of which are very good—but what’s the point of using a laptop if you have to tether it to a box to get good sound?Klipsch has a better solution: The ProMedia 2.1 Wireless uses a USB transmitter to send audio from the host PC to the speakers over the airwaves. The speakers themselves are all hardwired, with the amplifier tucked inside the subwoofer. And lordy, what a subwoofer it is. There’s a 6.5-inch long-throw, side-firing driver housed inside a bass-reflex enclosure with a front port. The sub cabinet also houses the wireless receiver and the 200-watt amplifier that powers all three channels. Klipsch claims line-of-sight range of 30 feet and our experience backs that up. If you’re looking for a wireless audio system that will send audio from a computer in one room to speakers in another, this isn’t the right solution.
