Brass screws make a real difference on Dunlavy s ?

On most speakers brass DOES make things sound a bit better, on single-drivers often a big difference.

Shubert,

On what do you base that statement ?

Good Listening

Do not forget to send the screws for immersion cryo, not the spray-on.

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).

Rcprince is absolutely right on his post above. Also, if you don't have inserts and your screws are just going straight into MDF or Plywood, you run the danger of stripping the threading in the cabinet. Be careful.

One other issue I've read about concerning tightening the screws is that it can be possible to tighten them too much to the point where the frame/basket gets out of true. In those instances, the driver and surround are not operating in a true single plan and the pistonic motion of the driver can be affected.

Not sure if this is true or not, but if you think about it, it certainly seems entirely feasible.

Back to brass screws. I have no idea if it makes a difference or not, but years ago, it was suggested as a tweak to the owner of Omega speakers. Louis (The owner) liked it so much that he now uses brass screws on all his models.
