Replacing driver screws with brass screws


There was some discussion about this on Millercarbon's thread about the Moab speakers, and I wanted to pursue the subject further without interfering with his thread.
As I stated there, I have heard about this practice for quite a few years, but never tried it because it seemed like one of those lunatic fringe ideas; and even though I actually really enjoy trying tweaks, and have found many of them effective, I just was not prepared for what this one did for the music coming out of my speakers. 
Specifically, it improved the detail in ambient trails, focus in general, complex harmonics in voices and stringed instruments, and instrumental separation. It is not subtle, and it is immediately noticeable.
So, I am curious to know how many of you out there have tried this, and what your experience has been.
Thanks, John

We have a resonance tuning method that can be performed from the outside back of our cast cabinets. Never tried it on mdf or the like. Couple of degrees and you get a different out come.Tighter  slightly faster and maybe thinner..looser a little warmer and full. Been doing this since 2003. Installed the new Purifi driver just incredible now I need to install the new resonance tuner.  Tom
We do the same with an internal crossover mounted on our points and the tuned externally like the woofer. Big difference there as well. Cant do that on springs or such musical deletion devices. Tom
