Could someone help me choose the tuning and material of this enclosure? The tuning options are 29-37hz
The subs I have are 12” Skar SDR’s. Amp is a Skar 1500.1D

Materials, I'd say 3/4 mdf or a high quality void free plywood. Double up the baffle and/or brace the baffle. I'd say minimum ~1.75cuft (as does Skar). Tuning depends on what you're trying to accomplish. As low as 30hz and maybe as high as 45hz.

Great, thank you.

Great, thank you.

Just remember when you pick a tuning frequency as you go higher the box gains efficiency, but loses low end and tends to become peaky.
