By the way, I've been considering buying this:
They look quite nice, but how do they sound? That is the most important point, and the one that you alone are best able to judge. Can you audition them in person before buying?
A couple of months ago I purchased a KLH 5.1 speaker system with powered subwoofer, sight unseen (or should I say sound unheard
). I figured how could I go wrong for $30? The satellites have 3.5" mid-range drivers and 1" tweeters. The "subwoofer" has a 6" driver and 50-watt amp (I think).
I don't regret the purchase at the price, and I am glad to have a 5.1 speaker set for so little money, but I have to admit they aren't very good quality. Oddly enough, they are weakest in the treble range, not the bass. In terms of pure sound quality (neglecting the surround aspect), my old Yamaha YST-MS50 2.1 system blows them away. You don't get what you don't pay for...
By the way, does the amp in the subwoofer of the system you posted power just the subwoofer, or does it also drive the satellites? If it also powers the satellites it is an even better bargain. You can then hook it directly to your computer's sound card.
