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?

I haven't listened critically,yet. However, I do notice a slightly less fatiguing sound, and I changed the toe-in of my speakers a little (toe-ed them in more). They are easily removed, and the TopStick used to adhere them will not leave a residue, so there's no penalty in trying them.

The Absolute Sound just gave the professional version of these tweeter surrounds an award, which you may have seen.
I wasn't aware of The Absolute Sound award as I don't subscribe to any reviewer mags any longer. Many years ago, I subscribed to them religiously.
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.
