I hate to make another 4th order thread but I've been reading through them on a few forums all night. I would like to design one myself to save some money since the only good 4th order designers I've found want like $40+. I don't need a fancy 3d sketchup, that's what I have a imagination for.
I just have some questions to help figure out what to do here. I know the basic ratio is 2:1.
I'm looking for a fairly flat response from around 25hz-50hz. How do I go about figuring what to tune the front chamber to? Is 15 sq/in of port per cube typical for these enclosures?
Also, how do 4th orders effect the handling power of the subs?
subs are 2x sundown sa-12's
Max dimensions are 35l x 30w x 19h
I'd like to port through the ski hole, which is 8" x 17.5"
