[quote name='Over easy']The speakers are okay if you don't have a high demand out of your sound systems. I use it for my laptop (with an external sound card) and it's fine. One problem I have with it is that the rear end speakers are not loud enough for my taste. I don't remember correctly, but I don't think it has center/front/rear volume control.
O, I got it for $40 at one point, so if you can wait, you should.[/QUOTE]
The unit itself doesnt have adjustments. Thats handled via the source (pc/soundcard,etc)
These are entry level 5.1 speakers. Small box, small sound, etc. They work great for their designed purpose but hooking them up to anything with power will show weaknesses.
