Let me preface my post, I am not a woodworker, rather I am a hack that can follow or copy other's great ideas. I used a palm router with a 3/32" straight flute router bit to make this furniture joint. The depth is also 3/32". A straight edge clamped to the speaker provided a guide for the palm router along the wall and baffle joint. Very straight forward cut with minimal jeopardy.
The veneer is 10 mil thick mahogany. Better Bond heat lock glue worked great for my novice skill set. I over thought the veneering steps. I did both sides first, then the back and finished with the top and bottom. I applied multiple coats of Odie's Oil and the end product is a uniform warm tone in a satin finish. I spent too much time worrying about a 10 mil piece of veneer. The brown finish covered any imperfection.
The baffles, I sprayed multiple coats of Spray MAX primer, sanding between coats. Final color is 2K Spray MAX hot rod satin black.
I am very happy with the final product.
I will post a photo of my just completed OB subs. The companion pieces to my NX's.
