In Reply to: how often do you folks tighten driver mounting screws ? nt posted by snkby on March 22, 2007 at 21:54:12:
Almost every used speaker I get that I like I swap drivers around, and listen.This goes for woofers, mids, and tweeters too.
Most have no idea just how some speakers can be improved by this simple tweak!
It is time consuming, true, and sometimes one must admit defeat, and put all back "like it was".
But 9 times out of ten, a speaker can be improved by just swapping drivers around.
I always put em in upside down from the way they came out too, just for kicks.
I don't really believe in supension sag, but I sleep better .....
Oh, and I also take Ice Cubes and "Cryo" the terminals.
Gotta keep those electrons happy ya know ??

And you do that on your, what is it, 600 pairs of speakers?

Have to be careful with that. There are a number of speaker manufacturers that test and group drivers and crossover together, so swapping is likely to worsen speaker to speaker uniformity. For example, in the later examples of LS3/5a, KEF used to sell driver sets that matched woofer, tweeter and crossover to the OEM manufacturers, to be installed as a setin the enclosure.
I trust MY ears more then the claims of a manufacturer that they "test" and match drivers/crossovers/etc, etc.Plus, I usually buy used speakers with some age on them.
Things drift with age, and even if matched, they can drift away from spec.Sometimes simply swapping drivers yields vast improvements in sound, and sometimes it don't.
No big deal if it don't work, I make notes, and can always put it back to stock.
