I have a sub enclosure design that I will make in the future. I want SPL and deep bass extension, so this is what I came up with
For the BTLs, it will have 8.5 cubic feet, as for the Qs, each sub will get .5 cubic feet.
What do you guys think? I'm not sure if the Qs will get tuned to 25Hz with just only .5 cubic feet of space though
