Over the years, we've seen a handful of Bluetooth speakers make their way into our office for testing, but the category has never taken off despite the appealing nature of wireless audio streaming.
Part of the problem is that Bluetooth speakers tend to cost more than your typical powered PC speakers do. Costing about $150, Creative's Inspire S2 Bluetooth speaker system isn't cheap but it is fairly affordable. It's also very small, especially for a 2.1 speaker package that includes a separate subwoofer.
As far as exact measurements go, the Inspire S2's cube-shaped sub is 9 inches tall by 8 inches wide by 7 inches deep and can be easily hidden under a desk. The sub is black; the tiny satellites are white with black cloth grille covers. They're so small you'll barely notice them sitting on a desk.
