Brass screws make a real difference on Dunlavy s ?


As some of you know, I have just about every model speaker John Dunlavy ever designed. I've tried a few tweaks, but never replacing the standard driver attachment screws with brass ones. I've read some posts that it really does make a difference, but before I make a run to the hardware store, I would appreciate any thoughts on the matter. Thanks in advance!

Brauser, the skepticism you likely read in my post comes from the perspective that what you're doing isn't tweaking (or incorporating a minor change, as you put it), any more than inflating car's tires back to spec means you're tweaking that model's gas mileage potential, or fixing a hole in your roof is tweaking a house's weather sealability. All of these things, like tightening those screws that you found needed two full rotations, is simply bringing the item back up to spec (again, assuming that specification for any speaker doesn't include loose drivers). I'm not saying you shouldn't do it, I'm saying that re-tightening loose screws, at least in my personal estimation, isn't a case of finding new improvements in a system, it's simply a case of returning a system to the level you should have been enjoying all along if the screws weren't loose.

The upside of course is that maybe this thread will remind everyone to check your screws, in case the manufacturer did a poor job of securing the drivers and you never noticed before. So, screw away!
Begator, seems to me you enjoy splitting hairs. Am I to understand that tightening screws to their original tension level is not a tweak, but if they are now secured better than new and an advancement in sound is the result, that somehow this is a tweak?

I guess if drawing these distinctions makes you feel wiser and better about the discussion, I say go for it. Hey, it's a free country.
Brauser, actually your OP was focused on brass screws not tighening existing screws? Have you forgotten already? Lol
No Brauser, I'm saying that if you're really experiencing a case of discovering a level of tightening that was either beyond the engineering capability of your speakers' designer, or simply wasn't important enough a quality control concern for the designer to care about, then you bought the wrong speakers. Think about it...what exactly does "better than new" mean? If we can agree that every screw can be tightened to a maximum torque level and perfect seating, either the speaker manufacturer assembled the speakers to specification, or they didn't. And again, if the difference between good sound and better sound is two turns of a screw, what does that say about the speaker designer if they missed that detail when designing and building the speakers? Focusing on "splitting hairs" is missing the point entirely. If you don't see this, then we might as well start a thread about how if we tighten the lug nuts on our car wheels to "better than new" the car will ride better.
