Cheap tweak from Virtual Dynamics:

"I love cheap tweaks that have potential to improve sound."
Have you heard of EnABL?

Can't beat $26.00

Cdc,
Very interesting. I remember a fellow writing in Audio Amateur some years back about gluing felt strips on the face of a cone driver with the idea of breaking up standing waves and how well he thought that worked. If I decide to EnABL my drivers I will use the AVM acoustic paint instead of the paint sold in the kit. Tom

Hi Tom,
One guy used toothpaste on his Jordan's as a reversible experiment. Someone else used Post-It's!

I don't know why the links look so funny but they work.

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.
