I wouldnt use a single 4" per 2 12"s for listening...try to use 1 port per sub..

Im using two 6 inch ports for a single 15.....I dont think one 4 inch for two 12's is enough.

One 6" per 12" would be the lowest i'd go (or two 4" per sub)

I plan on using two 4" ports for a 10. So... no.

I have a single non flared 4" with a 12" and it makes alot of noise.

I would go with 6" flared for each box //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

One 4" = approx. 12.56 in^2 of port area.

he should be more than fine with 1 4" per 12...2 is almost over kill imo..

thanks guys i'll give 4 4'' a try

depending on the subs, some subs need 35-40 sqin of port area like SX and DP

Relatively speaking, one 4" port isn't much port area at all.

For a daily driver box, the minimum i would use for a basic 10" sub box (type-r, CVR, etc.) would be 20 sq. in. (or two 4" ports).

Not to say that one 4" wouldn't work, but i would think there would be some port noise and you wouldn't be extracting the full potential out of the sub.

My daily driver box is 1.5 cubes with 12 sq. in. of port, and i get shuffling from the port like no other.

do you think 4 mt 15"s would need more than 7^3's and 50^2's of port?

ive never messed with these things, seriously...

You would use a single 4" port for a 12"?

 

[xchaosx 10+ year member]

last box i had built for the 2 12 geddons had 120'' of port in a 9 cuft' box i may just run slotted ports i know they work

 

[2loud4u 10+ year member]

My box for my single 12" mt has 50 square inches of port area.

i use 2 4" areo's for my 15" brahma in a 4cu' box. with only 1200w it did a 146db at 38hz. i use this box for daily driving and didn't notice any port noise. on the other hand, i have made a similar box, 4cu', and 58sq" slot port and noticed almost no difference in spl.

in your case i do agree that you should go with 1 4" port for each sub.

seems to work well enough for 2 mt 12"s and a t3000?
