I'd have to go with Peter on this one. My Duntech Princess speakers benefited from tightening the screws holding the drivers periodically, especially the woofers, but you do have to be careful not to over tighten (the Duntechs had inserts for the screws that could come loose if you went too far with the tightening).
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!
