Dave, the guy that designed all the cabinets always specs 15mm birch ply, I happened to have half a sheet knocking around too. The baffles are my own addition though - 30mm English sycamore. Bit worried the drivers will be “crowded” by the thickness, though I have chamfered the back of the cut out. The timber will look stunning when it’s sanded and oiled, trade off between form and function.
