Hi Bill
I’m going to build a Simplexx 1x12 ported and thicknesses of plywood I can purchase in my town are 10 mm and 15 mm. Not 12 mm close to 1/2 inch. 15 mm is better than 10 mm of course for the sound but what about internal volume? Can I use you external dimensions and size of the ports with a 15 mm thickness? Internal volume will be smaller and frequency tune will change …
Thanks
Vinceom

Re: Plywood thickness
Th internal volume won't change enough to be a concern. Just maintain the same port area.
You should have your location shown on your profile so that others in your region may be of assistance.

Thanks ! I edited my location but not sure that there are many cabs BFM builders in Normandy
Re: Plywood thickness
Just curious. Could you use 10mm ply with a little extra bracing to save weight rather than using 15mm ply? Or would the extra bracing weigh enough to not make it worth the effort? Also, I assume this is baltic birch ply, but the OP doesn't state it.

Re: Plywood thickness
50% more bracing would allow 10mm.
