    w3's in a sealed box should sound nice no need really for someone to build you a sealed box though...

    Re: what box..

    Depending on the area you have to work with you can do them sealed or ported. Which ever works for the situation.

    You can pick up sealed enclosures fairly cheap, you just need to ensure they are the correct volume. Many times they say they are xxFT^3 but are really yyFT^3. Also you would need to seal up the enclosure if you were to purchase a prefab sealed enclosure. They are notorious for leaks.

    Re: what box..

    For a sealed box if you are given the outer dimensions of 14" x 14" x 9", you can calculate the net volume by subtracting 1.5" from each dimension (MDF is 3/4" and two sides equals 1.5"). So 12.5 x 12.5 x 7.5 = 1170. Divide that by 1728 (amount of square inches in a cubic foot) and you are left with 0.68 cubic feet. If the manufacturer is advertising 0.9 cubic feet then you know you are being misinformed.

    This is exactly right.

    However, you also need to take into account your subs displacement to ensure you are at the correct volume.

    Re: what box..

    ok so on JL's site, it says the ideal sealed box is a .625 cubic feet box (measurements given are 18in. x 11in. x 9in) do i just multiple everything by 2 in order to get a box to house both subs or how do i go about that?
