how to secure back panel of a speaker cab

[Domanation]

I am tried to use t nuts and was met with frustration. Now I was thinking about usind drywall anchors or just plugging the wholes and using screws
I'm worries about the screws striping out over time though. Any suggestions

material the screws are going into?

grained wood?
ply?
MDF?
Silly Puddy?

Wood screws work well if the hole is drilled to the right size before hand.
Coarse thread drywall screws like you're perhaps thinking of sink well in to most wood as the main shaft is thin, but they are brittle and can break under force. Not that this would happen in a speaker cab, but that's part of their makeup.

Those tnuts you mention are usually used for wood that may not have a strong grain or opposing grain to grab onto so it uses the back side of the surface being secured to.

Yep good old drywall screws hold the whole planet together.

Its going through three quarter inch plywood and into two inch pine. So you think screwss are good enough. I'm worried that with swapping speakers and servicing it might not be the way to go.

# 8 wood screws 1.75" Is what I've used with the associated # 8 finish washers. The same way Marshall, Ampeg, Crate, Mesa, Bogner, etc have their baffles screwed on.

Most cabinets are screwed in. They won't strip out unless you're going to take the rear baffle off every other day. Even if they do strip you can plug the hole with toothpicks and wood glue and it will be as strong as it ever was if not stronger.

Is this a custom build?

[Domanation]

Yeah it's a custom and the t nuts were my first real hiccups and turns out they are unnecessary.

This is the size that I've used with the most amps. Oval phillips head stainless steel full thread screws. Sometimes I will drill out the stripped hole and epoxy in a flush hardwood dowell. Then a pilot hole is drilled and the new screw is waxed with clear shoe polish to make cutting new threads in the hardwood easier.
