If you've been using the tinny little speakers bundled with your PC because you don't want to spend $400 for the Klipsch Ultra 5.1 then Logitech has the perfect solution. For less than $80 (79.95 to be exact), the Logitech X-530 Speakers provide 5.1 surround sound with rich balanced sound and minimized distortion. They may not be as powerful as the Klipsch set, but they look deceptively high-end.
The X-530, and its cheaper 2.1 cousin, the X-230 (49.95) will be available from Logitech later this month.
