Are you talking about 2 seperate 3.67 cubic feet enclosures with one 4" x 10" port, or with 2 ports per 3.67 foot enclosure? A 3.67 cubic foot enclosure with two 4 inch diameter by 10 inch long ports tunes to 38 1/2 hz or so, and the same size enclosure with only one 4 x 10 vent tunes to 27.2 hz. Make the fiberglass at least 1/4" thick, as this is supposedly comparable to 3/4" mdf for strength. As far as the angled ports go, im not sure. I would think make the mid line the actual reccomended length. Again, not sure. Sorry I couldn't help more man, im new to all this. Good luck with the project!
