i am curious how you got the measurements to have the port in the middle of the drivers, versus on the next to them? i am going to be doing a build in the next few months, and i am going to be using 2 alpine type-r 12's, 5 cubes, @ 34hz. i have some plans that will work for the available space: http://www.subwoofertools.com/forum...12&Vd=.2&NumW=2&Vb=5&Fb=34&Qts=&Vas=&Fs=&CE=0
but i am trying to find plans for a center-port enclosure. if you could help out in any way, i would appreciate it.
Thanks!
