Ive been kicking around the idea of a 4th order.
First, and most importantly, Do the DD 9512's do well in 4th orders?
I'm currently running a ported box tuned to 38 hertz in the trunk of my BMW 530i with only a ski pass through. My idea was to build a 4th order like like the pic I have posted below to do a sort of blow through. What do you all think?
I tried downloading winsid, but I cant use it well. I know a lot of you guys know how to work this program well, any suggestions on front and rear chamber sizes, along with port length and such?
Sub is DD9512 D4 2000rms
Wanting a tune of between 28 and 32 hertz
Thanks in advance
