Great tip.. are you speaking from experience Bruce?
No, but I had a scare or two......one thing I do now if I'm screwing from the front of the driver is to put one of the baffle cutouts on top of the cone when screwing in the driver. I've got a bunch of those BB discs hanging around from all the speaker builds.

I'm not even sure I know what those look like....do they have a washer head?

They do. I always have some on hand for any job where I want to use a screw that doesn't countersink.

Another great tip.. that one should stop me poking the screwdriver into my finger instead when I'm fitting drivers!

Do yours have a fine thread Bill? Nearly used them in an 8" AT for the driver once, as it was late and l wanted to test it. Also liked the washer head for that purpose.
I'll fit this next panel, then off to bed...

Coarse thread. They're expressly designed for going into plywood, making them ideal for driver mounting.

A lot of progress was made this week.
They are both as far as I can get them without buying more plywood.

I checked my local fancy wood store, and blthe 1/2" BB sheets are currently $65 here in Northern Arizona, and very available.
