I haven't used birch much, always used MDF. I like how easy it cuts and it's stiff af. I'll use birch on the next box I build probably.
This box will be 2 cubes after displacements tuned to 31hz. It's got 40.25 sq in of port area. Forgot what the gross olume was. Gonna run a sundown x12 on 1600 rms in it.
Old box is like 2.5 cubes after displacements iirc. Tuned to 33hz with two 4" aero ports. It has 2 RE sxx10 in it now. I built it a few years ago and I've improved my skills a lot since so I figured it was time to update my personal box lol.
