Cheap tweak from Virtual Dynamics:

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.

That makes sense. When I replaced drivers on my Castle Acoustics speakers, the replacement drivers came with new foam gaskets. I suspect over tightening would eliminate the benefit of the gasket.

The VD video makes mention of not using too much torque on the screws.

Hi Kirk,
I used to own the Meadowlark Osprey. Funny how I never knew about the driver damping material, however, I never had to replace a driver while I owned them, nor did I ever have a thought of needing to check for their driver screw torque. Too bad that Meadowlark's no longer around. They sure made some great speakers.

I posted a little review of the felt tweeter surrounds in the product reviews for tweeks a while back. I did not like the effect after a while. Could just be me though.

I just received an e-mail from the manufacturer of my speakers after I asked them if the screws on my speakers had to be a certain torque. His response was, " You want the screws to be firm, but not too tight to avoid stripping the screw holes."
