What I'm shooting for is all around listening, from lows to 40's in the HZ range. I have a 15" AA havoc and 1500rms to feed it. This will be going into the trunk of a 300c. I can make the box MAX 32wX17.5tX20-25d.
This is what I came up with.... 1.5sealed, 3ported tuned to 45hz?
This was my first attempt at trying to design a 4th order, so it's probably a bad design lol.
