Brass screws make a real difference on Dunlavy s ?

When people wonder "Why don't more people love (high end) audio?" threads like these are exhibit A. Audiophiles don't get a nutty reputation out of nowhere. ;-)

It's a screw thread not nuts. 🃏

Wait a minute...are you guys talking about re-tightening screws that were loose? Which would be like proclaiming that your car is less jumpy because you replaced the broken motor mounts...well, yeah, duh. Or are you saying that you're actually hearing better sound by over-tightening screws that are already properly seated, and you're tightening them beyond what the manufacturer's quality specs dictated?

If it's the former, nobody gets a trophy for discovering they get better sound if the drivers aren't about to fall out of the cabinet and crash to the floor. But I'm sure nobody would debate that...sorta goes without saying.

If it's the latter...are we to conclude that these speaker designers - keeping in mind that you guys aren't talking about white fan specials, but well-designed products from highly-respected manufacturers - put all that time into creating these fine products but only half-assed it when it came time to attach the drivers, and they'd have actually created better products if only they'd taken a minute and turned their screws a little further?

Have to be candid here...I can't read this thread without repeatedly checking the calendar to make sure it's not April 1.

It's obviously a magnetism issue. Even teflon screws will illustrate that. The ferrous type screws cause a subtle but quite audible perturbation in the magnetic field lines of the speaker magnet. Another option would be to demag the screws periodically. Be sure to demag all those tiny ferrous screws on the component chassis while you're at it.

Also energy can be drawn in a particular direction by mechanical force or tension. If you have a speaker driver that is to be secured with multiple fasteners then all those fasteners should be tightened the same. Like a drum head the energy should be spread evenly around the circumference. In this way the wave launch from the driver will be more linear and piston like on all areas of the cone or driver. Tom
