    well i think the 15" CVR is supposed to be around 3.5 cubes a piece. so, 7-8 cubes would be fine. tune around 32-36.
    as for the port(s), i would recommend a single slot-port for two reasons. 1, it is a lot easier to design, and 2, it adds overall strength to the enclosure. i would also recommend some internal bracing, and/or a double baffle.
    another option is dual slot-ports. pros to this are add strength. cons are larger box size (not by much, but a little larger than a single port), and its tougher to design.
    Check out this site for some help designing your enclosure. i took the liberty of inputing your info, but feel free to play around with it and see what you can come up with. http://www.subwoofertools.com/forum/...&Vas=&Fs=&CE=0

    i think dividing the air space cleans up the sound. also it adds box strength. and you could put a single port on each side if you do that. i think it would be a good looking box. strong and loud aswell

    i think im going to divide the two speakers, so if i do that and i put a port on both sides...i would just put the speaker in the center of the box right?
