You use glue on your cab as well as screws?

Hi all..

I was wondering if glue on the back board of a rect 4x12 or between a guitar speaker and the wood it is fastened to .. Does glue alter the sound of a 4x12?

Or did I forget to do something very important in sealing my cab shut?

I highly doubt glue will alter the sound of a guitar cab. I would think bass cabs with greater pressure would be different if any. Just a better seal i guess and sturdiness.

The speakers should have some foam or paper gaskets that sit between the baffle board and the speaker. Some speakers have had this gasket glued on, others haven't. The glue is basically for ease of installation as it's the gasket that seals the air out rather than the glue.

As for the back board, I've never glued one in place, and if you do glue it in place you're going to need a wrecking bar to get the back off that cab again.

thanks for the posts... I guess my cab is A ok without the glue.

DO NOT use glue! If it's a rear-loaded cab you may one day want to get the back off again.

Mesa use a double-sided adhesive tape, but even that is (IMO) unnecessary and makes getting the back off difficult. A decent number of screws done up tightly should be all it needs.

Is this just for the back-side of the cab? I couldn't believe they would build a cabinet with just screws, i've always used both glue and screws when building cabinets.

Yes, absolutely! The question was about the back board.

The cabinet shell itself should be dovetailed or fingerjointed (or at the very least, rebate-jointed) with glue and should be as completely rigid as possible. If the grille is a separate frame with the cloth on, the baffle can be glued into the cab as well which makes the whole thing massively strong, but it may kill the resonance a bit. The classic Marshall cab construction has the cloth directly onto the baffle (with an edge spacer) and then screwed in.

Ok thanks for the info and if I may start a discussion... How would one put in longer mounting speaker screws?

And how do you remove the cloth grille from a Mesa 4x12
