Hi,
This project is more woodworking than electronics. I am going to share the construction of a pair of speaker grills for a vintage Cerwin Vega AT-12 loudspeakers. This shows How I did for the Cerwin Vega's, the techniques should work for other brands.
I have bought two pairs of CV speakers, AT-10 and AT-12. The AT-10 speakers came with grills, the AT-12 did not. I used the AT-10 grill as a guide for fabricating the new grills.
I cut the new grill frames from 3/4" MDF board. The outside dimensions are 14 x 26 inches.

There is a 45 degree bevel on the front side:

And recess for the bass driver on the rear side:

I found similar pins at two places:

To make these pins work, I added some spacer washers cut from 1/4" plywood.
