you dont even need that much //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif you could get away with 80's

is it going to negatively effect it then?

you dont need a box that big either, if i had that sub and enough room id try like 7.5 with 120sq" of port tuned to about 32

nah i wanna just get real low...not trying to get loud...

well not trying to get super loud

my 6.5cubes with 80" of port got real low, you dont need a giant box to do it. 100" of port is kinda small for 10 cubes

well after displacement its just over 9 cubes....and almost 110" of port....im not gonna have port noise am I.......i hope not

 

[mazdakid 5,000+ posts]

probably not, but id still make it smaller, and the port bigger

power handling isnt going to be as good in the huge box either probably. what does fi reccomend?

You really should just go with what mazdakid said, 6.5cubes, 80 square inches port. You seem to think that the bigger the box gets, the lower and better sounding it is. This is not true at all. The tuning frequency, and port area are by far the greatest factors.

Fi recommends 8-10 for ported....doesnt say how many square inches of port
