what do you guy's suggest making a box out of?
 

i know ive seen it before but my weak search didnt find anything. what kind of wood would you use? do you caulk it on the outside or inside of the box? any help is appreciated

and how do you find air space again? Length x Height x Depth?

MDF - Medium Density Fiberboard. I would get the 3/4" of 5/8" thick stuff. 1/2" might be alright bu the thicker the better. You want to use glue and screws on every seam and then caulk/glue all the corners from the inside to make sure their is no air leaks.

air space is best estimated using a calculator and some simple math and by deviding the volume into simpler shapes like rectangles and triangles. If you wanna get really accurate, use sand and add .25 or .5 cubic feet at a time until you fill the box, but usually that kind of precision not needed...

thanks bro

incublinkus pretty much said it.

.75" MDF is the most popular. you want to caulk from the inside. if any of the sides are very long, more than about 2ft, i would use a brace to make it more sturdy.

when making calculations, remember to account for the space that the basket of the subwoofer take up. that spec is on the sub's spec sheet. and the same if you use braces.

how do i find air space again?

L x W x H divided by 1728 = cubic feet

in inches or feet or what?

example:

12" x 12" x 12" = 1728

1728/1728 = 1 CUBIC FT


also, try to avoid a cube as a box.

I use liquid nail to glue it together before I screw it. Then I I use way too many screws(one every 2 inches) and seal it off with silicone sealant. Silicone can damage the cone I''ve heard so you have to let it dry for 24 hours before installing the sub. Why would you avoid cubes?? My Boston spec sheet sugested a half of a cube as a box. Goodluck!
