So I have this old school Memphis Mojo 15 and I ordered a recone kit from fixmyspeaker.com thats more upgraded than the stock cone (ex. flat wound coils, triple spiders, 1800w rms rating).
I need to build a box for it but PSI cant give me T/S parameters for the new cone. They recommended a 4 cu.ft. box with a vent tuned to 32Hz (although i would like it tuned lower, maybe around 27Hz or 28Hz), they also gave a recommended port area which i think was 30-70 in^2. I'm wondering how I'm supposed to design a box without T/S parameters? I have WinSD but it wont let me start a project without subwoofer specs. I also can't find the displacement of the subwoofer, I'm guessing its around 0.3-0.4 cu.ft.?
What would you guys recommend? i tried looking through the thread with all the different box designs but the ones i found didnt list a port tuning or overall box volume.
I also want a box with the sub on top and the port facing the rear. Its going into a Chevy Tahoe.
