I just built a box for two IA 12" 187's and was curious as to what others are recommending or are using and at what frequency. I built the box as close to 5 cf^3 as possible with a 4x15" port 12" deep. The subs sound amazing but that port just seems huge. It gets really low but seems like midbass is lacking a bit, I was thinking of shrinking up the port a bit.
I built the box 37 1/2" wide by 16 1/2" tall by 18 1/2" deep and know I'm supposed to subtract all wood, driver displacement but I guess I didn't figure in the actual port. I subtracted the wood but now that I think of it, the 4"x15"x12" I have for the port should also be taken out correct?
I don't feel that much air flowing out of the port and was considering using two aero ports, maybe 4" or would that be too small of area. It'd only be about 25 sq in instead of the 60 sq in it's got now. I also what thinking of taking 2" of the depth if I did this bringing down total sq ft to about 4.5.
Thanks in advance.
