SOURCE: box dimensions for 15 in cerwin vega

do you want the box ported or unported (holes or no holes) if you don't got a lot of room than you dont want a ported box. keep in mind the box has to have the correct amount of cubic air space or you could seize your sub... if you're building it make sure you use OSB board (oriented strand board) or MDF board(medium density fiber) your sub needs .7cubic feet of air space in an unported box

10" subs need 1 cubic feet. 15" subs need 2.5 cubic feet. install them on its own volume of the box...

You can't convert cubic feet to square feet because cubic feet has an extra dimension, you could fit an unlimited number of square feet into cubic feet.

The formula for Cubic feet is:

length × width × height

The formula for Square feet is:

length × width

The formula for Cubic feet is:

length × width × height

The formula for Square feet is:

length × width

Cubic is measured in 3 dimensions, and square is measured in 2 dimensions. Need to re-phrase question first.

Make sure to use MDF for the enclosure and use 1 inch thickness and use braces as well. This is a beast of a sub woofer. So give it the proper power it needs and make sure that your box is very solid in construction. If installed correctly and given the right power, this sub woofer is bound to put a smile on your face and rattle your bones. I hit 142dB with only one of these subs and im sure if i gave it more power i could hit the 150dB range. DON'T FORGET TO GIVE IT THE POWER IT DESERVES. Have fun dreamsystems.

If you can access the inside of the sub box by removing the speaker, you may be able to measure the 3 dimension of each side of the enclosure. 1 cubic foot is 12x12x12 inches cubed. That is 1728 cubic inches per cubic foot. If you measure the inside dimensions of one of the enclosure sides as 10x14x8 inches, then that is 1120. 1120 divided by 1728 is 0.648 cubic feet. Alternatively, you could estimate the volumes of each side of the box by measure the outside, figuring out where the box divider board is, subtracting the width of the boards used to make and then calculate. Otherwise, I do not know the enclosure that that sub comes in. Good luck. Let us know how it goes.

Typically you use one cubic foot per sub, so a 2 cubic foot box will work fine. To build a basic one, just a rectangular box, using 3/4" MDF (excellent material for a box), cut pieces this way:

2 - 25.5" x 13.5"

2 - 25.5" x 12"

2 - 12" x 12"

This will give you an interior volume of exactly 2 cubic feet. Cut your sub holes out of one of the 25.5" x 13.5" pieces.

2 - 25.5" x 13.5"

2 - 25.5" x 12"

2 - 12" x 12"

This will give you an interior volume of exactly 2 cubic feet. Cut your sub holes out of one of the 25.5" x 13.5" pieces.

I've Got The Same Subs, I Got A Formula On The Net, Its Dimension Is Aprox 9 D X 24 H x15 W.

Although I Have Them In A Home Made Ported Box I've Made, Its Dimensions Are 8 D X 23 H X 17 W And Its Sound Pretty Damn Good. I Have A 2 Inch Round Port X 6 Inch Long. The Formula Says I Should Have A 3 Inch Long Tube.

Sealed box and somewhat large if they are 12's I usually try to get 3 cubic feet overall internal dimensions and generally the inside dimensions will be 13" tall 32" wide and 13"-14" inches deep. with no divider and make sure the box is sealed. Personally I like to phase the speakers backwards. Gives the bass a little more rumble.
