Enclosure tuning help

[MANTI5 10+ year member]

I have an enclosure designed a little while back and am now getting around to building. It was designed with 1/2 birch ply in mind but now the local places aren't stocking that too often, instead they have 3/4. Would someone be willing to look at my design and let me know what difference will be made if I use 3/4 for my design vs 1/2? If it's not going to be ideal I will just go the hour away to get the 1/2.

Well you can compensate for the thicker wood and adjust the cuts accordingly, you'll see a small to medium change in airspace and tuning depending on the size of the box.

Add a quarter inch to each side will make up for the difference in size of wood.
