Cheap tweak from Virtual Dynamics:

Well, after purchasing a Wheeler Fat Wrench, which is a real piece of junk...the hex adapter doesn't fit properly so the thing wobbles while you're tightening the screws...

...and after being unable to find brass bolts to fit my Dynaudio drivers...

...and after being unable to find a 3mm hex driver attachment for the Fat Wrench...

...I'm abandoning this tweak.

I was able to uniformly tighten 48 out of 52 screws on my speakers (the other four had slightly stripped heads), and I didn't notice any difference afterward.

Moving on!

Tvad,

I kept waiting for you to say the wrench lost grip of the hex driver, slipped and went through a woofer. A real relief to read you lost only time and not parts.

This is the same outcome as my test. I admit I did not even look for brass screws, although that is probably the valuable part of the tweak.

I could not find brass screws which were a close match. I did tighten the screws on my TAD 805SD a couple inlbs. They still sound great, especially for the price, but nothing startling to report here either.

Its the brass material 95% and the torque the balance..thats the measure of it all. The torque measurement device has much to do with adjusting for the shear strength of the brass material. Versus that of the inferior sound and greater shear strength of the steel usually supplied and installed by the factory. Brass is the metal of music. Tom

Yep, I don't doubt it. Maybe I'll get the courage to obtain the zillion brass bolts required for my 24 woofers and get to the job one day.
