I liked 3.6^3' @ 33-35hz w/~50-60^2's of port

I have nearly the same setup. Interesting....

i'll prolly be hittin up real soon ng for another box. i'm just trying to figure it out on my own. i never thought i'd ever use any of the math i learned in high school. i been using the formula on JLs site, and i been gettin some f'd up numbers. i'll look into it soon...

try 3 cubes at 32 hz if u can fit it...you won't be disappointed. i'll be running 3.5 cubes in my altima (that is if the alt doesnt die from just regular driving) at 35.

A 15 SX gets very loud in this enclosure with 1100 watts...still doesn't extend too low though, consider a slightly lower tuning.

goin with ~2.5 cubes net @ 32 Hz... should be built in about a week

thats for 1 12 right?

what do you all think, 1 12 ported low at about 2.5 cubes or 2 12 sealed at 2.5?

btw, i like the leftover trunk space of a 2.5 cube

I'd imagine with 2x the cone area the Sealed's might be a tad louder and probably have a little better SQ but i'm not sure

its low enough for me, unless ur trying to impress someone, most bass isn't below that level, let alone heard if it is.

my 1st box was tuned at 35 an it sounded really good for everyday drivin an i think it hit an 144 give or take alil but if u want something everyday i wouldnt recomend goin much higher than that ive had one tuned at 38 an one at 40 an there defintly louder but sq isnt what i would want for an daily driver.

I'm building a 3.5cu.ft. after displacement tuned to 34Hz with about 1400w to my SX15. It should be pretty loud

that should sound good^. hopefully ill be gettin the 15" by saturday. then ill see how much louder it was then the 12".
