    Sub box, porting specs and questions??????

    Want to build box something like this, fiberglass with MDF top (stole picture from Google)
    Sub box, porting specs and questions??????-img_9862.jpg
    Sub box, porting specs and questions??????-cg125b.jpg
    Two 8” Subs require .6 cf per
    1.3 cf total area built
    Square port 6.25 “ wide X 4.75” deep X .75” height = 22.26525 sq. in.
    Specs on Carsterio.com call for min 4.72” port length with 22.27 sq. in of port space
    11.5 mm Xmax @ 37 hertz
    Question # 1: Is this site’s calcs accurate for this setup?
    Question # 2: Looking at the right hand side of the box, will the narrow passage leading to the port act more like a slot port or will this illustrated setup work?

    Thanks Famous. I have sealed boxes now but want ported. My space and what I want leads me to a square port. I will get with 07 if he will help. According to the sub spec I need 42.5" of port per sub ........this calc tells me 22.25" for both.......hmmmmm
