Default thoughts on my sa-10 box?

I've decided to try a ported enclosure for my sa-10 just for kicks.
I'm thinking 1.0ft^3 tuned to around 33hz.

I'm not set on 33hz, it's somewhat of a guess as to what may sound good - I'm going for sq more than spl and listen to all genres so I need it to give me the accurate punch of rock as well as the lows in rap.

My box is limited to a size of 8"d x 13h x 33"w
The sub will pretty much be right up against the rear shelf of the car behind the passenger seats in a porsche 911 so I was thinking it would be better to go with a side firing aeroport over a rectangular port.

My box would measure roughly 8"d x 12.5"h x 31"w, making it 1.12ft^3 after sub displacement, this would be subject to change based on the displacement of the aeroport (which I don't know yet).

Using PSP's port calculator, with a 4" aeroport, I would need a port length of 25.8" to tune to 33hz. I'm afraid the sub would interfere with a port this long.

So, am I on the right track here or just way off base?
Can aeroports be configured to be that long?

do you already have the 10 cuz if not id go with the sa8, in that space you will be much happier imo.

also how much power will you be runnin to it, and was it in a sealed enclosure prior?

Yes, unfortunately I already have the 10 and it's in a sealed enclosure right now. I wish I would have known I was going to try ported, I would have gone with an 8.

I can run up to 700rms @ 2 ohms to it.

Well the 4" aeroport will be too long and hit the sub so it's been recommended that I put a 180 degree turn in it like so:


The problem is I'm not sure how to make the bends or what materials to use.

I can't use a 3" port, which would work length-wise, but I will have way too much port compression.

It's also been suggested to me to use a passive radiator setup but I have absolutely no experience with these and am not quite sure where to begin.

Any suggestions?

PVC elbows at homedepot/lowes can give you the turn you are wanting.
