Unless you plan on running that sub at full output all the time, that port should do, especially in home theater. Going slightly bigger wouldn't hurt - Go as big as you can before you have to start bending the port inside the box.

we can tell you dont know the math behind designing a box....idk how the fuck you came up with 13 cubes....when the box is smaller than that itself.

this sub will most likely never see full tilt. no need in this living room.

ok constructive learn the formulas needed to calculate volume of a box...obviously if you multiply all 3 dimensions up you get the cubic inches...divide that by 1728 and thats how many cubic feet a solid sealed box is...then you have to calculate how much airspace the port takes up. that constructive enough dumbass

to go by there specs from their website you will need a much bigger box. 12 cuft tuned the 18hz

that is 12 cuft +port and sub and brace disp.

yea, once you guys started to say more port i was getting worried. i wasnt figuring on that much port. i'll have to take a tape measure to the area and see what i can come up with. maybe a full entertainment center with the base of the center being the box for the sub?

ok, new plan. full out entertainment center. new size will be 22"x22"x98" //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif that should give me more than enough room. anyone wanna come up with a plan for me?
