Hi Guys

I think this thread has pretty much run its course. There appears to be a consensus on the CHS frame as being useful.

There's interesting ideas on grilles which could be a separate thread for those who'd like to start it and make posts.

Thanks
Mark.

I got a call from a guy that had a issue with his expensive custom built speakers the other day, Funny how it leads me back to a question i had myself about mounting drivers.Apparently the screw holes are stripped, after many removals because of issues he had with cross-overs,rubber surround replacements etc. If the screw holes are back far enough from the edge and the baffle is a quality ply product, simply gluing in some toothpics or such is a easy fix but when you blow through the edge the repair becomes more complicated.

A year ago when i started building speakers it was clear that i wanted to build furniture grade enclosures that would last 100 years. knowing that they would likely outlast the drivers, concern about supply was a question but offering a replacement pair as a--warranty or something was talked about.

Mark as a furniture maker i would still love to see a front flange (excuse me terminology) 1/2" larger or even 3/8" in diameter to bring that screw well clear the cut-out.
probably to much to change and then theres the look but it makes re threading that hole after numerous removals so much easier

JUST MY 2 LOONIES WORTH

We just finished repairing speakers where the screws blewout into the cutout. They had a 5 figure price tag to, guess pride in workmenship isn't that important ever at $16000 a pair.

Do it right the first time cause fixing f***-ups is a pain

Paul, for sturdy protection, I'd tend to agree with the metal mesh. As it so happens, I've just finished building a little car audio sub-woofer box for a Rockford Fosgate 10" driver. It includes a very nice arrangement for accessory mesh grille that is captured by a heavy cast dress bezel that mounts over the generous tabbed mounting flange. Not an inexpensive combination, but very nicely executed. These drivers are quite nicely machined overall.

That looks like a well executes grill setup! I wonder if something similar could whipped up for Marks Alpair drivers which use the removable trim rings; perhaps using the rings as a way to hold a thin metal mesh in place.
