NEED SOME HLEP

[77-AUDIO]

New build will consist of 4 10\" SI BM\'s and a SAE-1200D

working on box design now, just need the port length and size figured out. I will post up the box design in a few min\'s with the total airspace before displacement.

I will also post up the specs of the speakers so I can get all of the help I need to tune it for SPL and Daily. I want the ports sticking out of the box. you will see in the picture.

need ports calculated. thinkg about 2 4\" ports. length not known.. thats where I need the help.
