Sunnyjim,
I think I gave you the wrong idea in my first post. When I said that Vandersteen yells at everyone, I didn't mean that he was a bad guy, or anything like that. Most of the time, I think he's just kidding around. At some point, he usually starts laughing. I'm not trying to make any excuses. I just don't want you to not consider a really good pair of speakers just because of anything I said.
As far as the setup instructions goes, he's right. Its very important you follow them for best results. If you didn't go through it, theres a formula you use to set properly set the back tilt. You take some measurements on where the speakers are in relation to your listening chair and put the results into the formula. Thats how you find out how much back tilt you need.
