I purchased these Bose speakers for my second computer at home. I purchased the Cerwin-Vega XD3's from Best Buy about 2 months ago, for my first computer. The reason I bring this up, is because I am very pleased with the sound quality of the Cerwin's, and I went to Best Buy to buy a second set of those. However, Best Buy was sold out of the Cerwin's, so for about the same price I bought the Cerwin's for, I decided to go with this Bose set, and try them out.
Once I got home, I hooked the Bose up to my desktop computer, and WOW, the sound quality from these small speakers is absolutely incredible! The vocals are spot on, and the mid level bass tones definitely have a presence in anything that I played through them. Also of note is the sound stage presence. I bring this up because, when you look at these speakers, they are just so small, that you just expect an adequate, at best sound from them. However, once you set the volume button on the speakers to the halfway up area, then adjust your computer's sound volume, you are going to be impressed at how loud and clear these speakers reproduce sound.
My conclusion in regards to the Bose speakers, is that if you have a budget of $100 to spend on speakers for your computer, these ARE the speakers to go with, hands down.
