Uh oh, your friend has been ripped of. These are terrible speakers, with no cross-over, very cheap speakers and no damping foam at all. A German hifi-magazine however has designed a couple of modifications so the speakers (Omni-Audio SA 12.3) will sound a bit better. The magazine is called 'Stereo', and it's issue nummber 4, april 1999. If your friend is really interested and can't get hold of a copy, e-mail me: [email protected] But to be honest, I think the best thing to do is to dump those speakers, go to a decent shop and listen to some speakers you can afford. Buy the speakers that you like best, and heee... they will even give you some kind of warranty.
