i recently purchased computer speakers, ProMedia GMX A-2.1 System for my laptop. after installing i noticed a constant hissing sound, and when i called cust service at klipsch they said it was just one of hte faluts of that model. i love the way these speakers sound but the hissing sound is ridicioulsy annoying, im probably going to return them. so i know im looking for a new set of computer speakers. Im wondering whats a decent brand/model for computer speakers, under 100.
