I purchased these speakers to go along with a new PC I had ordered. Going by reviews, it seemed like the speakers would fit my needs. After using them for a short time, I realized my $40.00 mistake. There is almost no bass! The sub-woofer is terrible!The speakers do not sound loud, even when turned up all the way. I have 2.1 Harman/Kardon speakers. The sub is 40 watts. I thought they were very good speakers, but 9 years old. I figured I was upgrading. I just wasted $40.00, the new Philips will sit in the box.My mistake.
