box help for 2 ava's

[mac bleeze 10+ year member]

alright so i now just orderd my 2 12s. I want to start working on my box soon as possible as i have only 3 woodshop classes left and a whole lot of mdf. I have 14"X30"x26" max dimensions i want to work with. So i was thinking i want the box around 4 CF. So i came up with 14X30X23. Now i need plans on how to do the port. i was thinking tuned to 28-32 hz. somewhere around there. looking for a pretty loud box but still hit those lows clearly. Any help would be good

If you use your old box, it would basically work. Internal volume would be a little different, as the subs displacement would be a tiny bit difference. Shouldnt really make that big of a difference though.

so this is what i got so far from a box calculator. please help me if im wrong. So for the external dimensions i have 31x14x24. I got port width of 3. the port is an elbow port and the first part is 19.5 and the elbow is 5.5. I got a tuning of 28.5 hz. Is this a good tuning for 2 ava's. i want it to get low and real loud

should work fine but if you want good SQ i would go with a tuning of 25 hz but thats just me
