    need help building a box.

    i have 2 subs they are cvr 12 2 ohm. the require a mininum of 1.75 sqft. the box they are in is
    side to side : 2ft 8 in
    top to bottom : 1ft 2.5 in
    front to back : 1ft 5 in
    port is 3in. wide

    there is a pic.
    if i want to add 2 more cvrs do i need 3.5 sqft per chamber since each 1 needs 1.75sqft or can i just cut two holes out on top of the box and be fine?

    You'd need a whole new enclosure. They will work better in more than 1.75 each.

    Re: need help building a box.

    I just built a box for 4 of the cvr 12s for my co-worker in a blazer. The port was 100 square inches 12.5 x 8 and was 34 inches long. The box was tuned to 30hz. It plays low and LOUD

    Go to ajdesigner.com for a free vented box calculator plus all the formulas to do it by hand.
