    ported or sealed?

    go on alpine's website and download the owner's manual if you don't already have a copy.

    Sealed, with a max depth of about 8 inchs with an angled back if that helps. i tried looking on the alpine site and the owners manual on the alpine site and i couldnt find much info at all regarding the recommended enclosure size for them. if you could get a link for me that would be great?

    Thanks

    If you go ported.

    2 - 2.5 cubic Ft after displacement. 32-35hz tuning.

    I only tried ported with my pair in multiple boxes. I like LOUD.

    is there any chance someone who is willing to help me design the box full on could shoot me an email to give me a hand thanks. i will most likelyy be getting it built professionally, but i would like to take some plans into them to show them what i want.

    The only way to do a wedge enclosure with 8" maximum depth is to build the box extremely wide or tall. For example:

    height - 14"
    width - 30"
    depth 1 - 8"
    depth 2 - 6"

    That'd be 1.13 cubes before displacement and I'm not even sure the sub would fit.

    Re: Alpine Type R Subwoofer Enclosure

    i was thinking of making the box fairly wide. my max top depth is 6inch and my max bottom depth is 11inch? does that make things easier?

    Re: Alpine Type R Subwoofer Enclosure

    i have scribbled some figures together and this is what i came up with, however i think these number would only work for a sealed box.

    Height: 14inch
    Width: 37inch
    Top Depth: 6inch
    Bottom Depth: 9.5inch

    And if my calcumalations are correct that gives 2.32cubic feet in volume???

    Is this Correct?

    Thanks
    Richard
