I've had my 9515 in two boxes so so far.

First was 4.25 net tuned to 39 hz with 101.25 square inches of slot port with the sub back and port back
Second was 3.75 net tuned to 40 hz with 50.25 square inches of areo port with the sub up port side.

Of the two, I liked the sound from the first box better.

I have a new one that is 3.85 net tuned to 36 hz with 66 square inches of slot port with the sub up and port back.


As far as good tuning, **** anywhere from 30 - 40 hz depending on application. I would say around 35 would be good enough.

I really like 36hz tuning on them. I installed 2 9515g's in my friends blazer, 8.25 2 6" aeros tuned at 36, and it plays fully from 25hz-65hz with authority. I would use a bit larger then 4, just IMO though:)

i hear the dd box specs arent good...well they are but there can be betterThey're definatly loud, but if you listen to any slowed down stuff and or like a great balance, tune a few hz less and it does pretty **** good:) Not under 35hz though, no point really.

Depends on the size of the box. Box volume, port area, and port length determine tuning...

how big r u talking?Like 4.5ft or so....depends what your listening to! Honeslty, best blend IMO for you is going to be 4.25@ 37hz, I havent used that exact box but being right in the middle, it should work great.

4.5-5.5 net should be good, and 40hz tuning will deffinalty play under 40 with some authority still..... be happy the newer 9515s take smaller boxs the old ones i used were better in 6 net and up.... but in my case they ive always went back to 39-40 hz tuning....no matter the box..
