One port for 2 subs?

Can I only have one port for an enclosure that has 2 subs, or do I need to have 2 ports?

No man you need 2 ports for each sub!!! So you need 4!!! //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Really one is fine and in some cases optimal...

As long as you're taking into consideration the port noise, then one is fine. Just don't have a small port for a lot of output. That's the only thing I would watch out for.

That would be more of a problem if he was going with two ports. Because they would be smaller than one large port...

Sweet!

I'm going to do 2 subs in a net 3 foot cubic ported box, tuned to 35 Hz, pushing 900 W RMS per sub.

Any other considerations?

What size subs?

1.5 Cuft per sub seems pretty small...

The subs are 12" TC-9's

I'm putting the box in a Sentra, so space is limited, what with the box, 3 amps and wiring.

Per TCSounds' website as well as REAudio's (compared TC-9 cpecs to RE's SX and SE enclosure recommendations just for the sake of comparison) they should be okay in a 1.5 cubic foot/sub enclosure. It's not optimal; 2 cubic feet is optimal. But, they both said 1.5 cubic feet per sub is okay. They said to tune the box to 32-35 Hz, btw.

Please correct me if I'm wrong in my assumption a 3 cubic foot box is okay.

It is OK but not optimal... As they said...

My e12a.22 has a recommendation of 1.5cF ported per sub //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

And it's a TC-9 derived motor //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

FWIW.
