Supra baffle for BIB?

This should be in the bib thread but it sort of relates here.

After making a flush mount for the driver in a BIB (not part of the original build process) I have the bumping on the rear of the
internal baffle problem.

I'm chopping it out as neatly as possible and will make a modification to the baffle with a router.

However, Godzilla made the wider baffle the whole length of the front.

This saves the agony of circle cutting.

What I'm wondering is, if I remove the baffle front made to measurement and put a new baffle across the whole front, it would change the horn path but avoid having to cut into the internal divider.

The change would be the depth of the flush mounted front by plus 3/4 inch or whatever the true thickness of the material is.

But with the repair in progress I'll prob'ly fix what I have.

Other idea is this:

Back when my BIB was new I got an oval wooden plaque from the
hobby store (the kind used to paint on or mount fish.) Those things also come in round.
Good point. I'm about halfway done removing the front. It isn't easy.

You'd think that caulk would separate with a cake spatula (like i thought when applying it) but it's been going slow. Even to replace, I have to complete the job and reglue.

The idea would be to make a shallow route in the shape of a taper
sort of like a shoe insole. The only part that touches is the very top
at the narrow part of the internal baffle.

Putting an new baffle over will change the look and proportion of what I have. Also screw up my grille covering.

This is the psychology of previous investment working.

Well after sleeping on it, I think I have a good compromise.

The depth of the flush mount is 3/16 in. Thickness of come
MDF or Masonite I have as scrap is the same.

If I make strips and put the strips on the side panels along the length, then place the removed baffle on a flat surface and capped with the cabinet, that should raise up the 3/16th inch, be even and ready to re-glue.

I can't say that I expect a lot of change in performance. And I can continue to use my decorative grille.

(From other threads, readers will know I've built a single BIB unit and
use various of my builds asymmetriclly to compare and contrast the sound.)
