You definitely won't be able to port 3 properly without doing a wall. What dimensions do you have to work with for 2 of the subs(ie: no wall)?

A wall might not be the sound he wants. I think 2 18's will do just fine.

Never said he should do a wall, just letting him know if he wanted to port three of them that he'd need to do a wall. I ran two off of 750 watts and was bumping 145's daily in a 32hz box...really no need for 3(even though I ended up doing it //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif).

if it was mine i would do 30hz but it depends on what you want

 

[reclessantics 10+ year member]

30 hz

word, yeah im going to go and make a box and see what happens, i would just lenthen or shorten the port right to adjust?

 

[reclessantics 10+ year member]

is it 5 net cubes per sub?

so i should make gross w/e the port and sub displacement at to it right?

just curious what others have tryed (gross, or net cube wise)

 

[reclessantics 10+ year member]

does the 5 cubes per sub, include the displacement, from sub and port, ect? is that exactly what others have used?

also with the box, would i need bracing with these 2 subs?
