    Look good? 12" BL (2.0 cuft - 35hz_

    Will somebody double check my figures here. It should be around 2.0 cuft tuned to 35hz (L PORT)

    14.00" h
    14.50" D
    35.00" W

    Total inside volume BEFORE sub & port displacement = 3.15 cuft

    Port dimensions = 3" X 12.5" x 36 (L PORT)

    Port volume = 0.95 cuft

    Sub displacemnt = 0.15

    0.95 + 0.15 = 1.1 cuft.

    2.0 + 1.1 cuft = 3.1 (within .05 is close enough)

    Thanks fella's.

    you forgot about bracing displacement. also your port is on the small side for an spl woofer. double-baffle is recommended if you're not putting the sub right next to the side wall IMO. And i dunno if the box is deep enough considering how long the port is if the sub isn't all the way against the side wall

    It'll have an L shaped port, it'll fit in there fine.

    FI recommends between "12-16 square inches of vent area per cubic foot of volume", 16 x 2 = 32. I should be at 37.5, so that should be good.

    You're probably right about the double baffle, probably go ahead and do that. As for bracing, the L port runs along the back wall so there isnt really any big opened unbraced area's... I was think it would be alright?

    I heard that caculator isnt very accurate. I used winISD, so I'm pretty sure it should be correct. I just wanted some opinions.

    What is everyones thought on winISD? Close?

    I'm pretty sure my design is right on (or real close), but I'm designing it for somebody else so I want it be perfect (or near perfect.)

    I've build a few enclosures now using winISD and all came out really well, so I think think its atleast fairly accurate.
