Hello All,
Before posting I did do some research about this and this is what I came up with. I am going to build a partial fiberglass box to hold two FI 15' Q, with the speakers facing up and port facing rear. I used a sample spreadsheet that someone here created. Here are some pics. Please let me know if this is correct, since this is my first time building a ported box. I forgot to include bracing, but will be doing some 2"x4" vertical and horizontal to meet in the middle of the box.
Thanks in advance,
