The Vibratite is the missing link, I think. I have always wanted to tighten my drivers' screws, but I always thought I would just keep having to do it, and that they would eventually strip. Great solution!
Cheap tweak from Virtual Dynamics:
Has anyone seen the short video from Virtual Dynamics showing the owner replacing all his speaker screws with all brass screws? I was wondering if you could hear an improvement. It's a cheap tweak, so I thought I might go to Home Depot and try out a set. What can I lose?
