I just got these speakers to replace an old pair of Altec Lansing AC90 speakers..the old style beige plastic box. I had read about problems with intereference, etc.....all I can say is that this system is absolutely great! No problems at all, and for the money - I paid $37 - you simply can't beat the sound. The desktop speakers are not tinny at all as some users state, and the woofer is deep and rich. I only wish there was a grill across the woofer speaker. I rate this system 5 stars. No, they're not Bose quality, but I am very happy with the purchase. It was a breeze to hookup.
