i would say birch but that does cost a body part lol
Im thinking Birch, too. Just save up a little for it.
MAX height is 12.5. The box would be 13 high if I used 3/4 mdf. I can't lower overall height, because I lose too much volume and I want to be able to remove this thing.
Yes, single 12 firing forward, it'll be sealed off of course.
