Another FYI - know your speaker when you do this. I have the Meadowlark Audio Blue Heron 2's, and I know for a fact there are layers of 'keldamp' between the drivers and the front baffle... this is a type of elastomer that helps to decouple the resonance and vibration of the driver to the front baffle. I was told years ago the amount of torque is very important as you don't want to over compress the material thus removing the absorbtion / elasticity of the layer... Not too sure how many other speakers have a similar driver setup. Just an FYI.
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?
