Nice Ian! I built a 4" mono for myself from 20mm quality ply. I highly suggest curving the baffle on all sides with a vertical disc sander. You have enough margin with 18 mm. I also rounded off the corners by hand. The stiffness is ideal for vocals. You can hardly feel vibration if any. I'm very curious what the end result will be dude. Good luck!
Very interesting Ian my friend 🥂.
