The Bottom Line The Klipsch ProMedia 2.1s' output quality is excellent on the whole, but a few minor problems prevent them from surpassing the competition. While it won't blow you away with its sound quality, if you're looking for an affordable PC speaker-plus-subwoofer system, the Z523 is one of the best speaker systems in its price class. Logitech's Z-2300s have been on the market for more than half a decade, but these PC speakers still pack a sonic wallop. The Altec Lansing Expressionist Ultra MX6021 PC speaker system is a superior combination of design and performance available at a fairly affordable price.
