I'm grafitting the board with questions about punch 18 (XLC) enclosures. I don't like the cookie cutter spec they provide in the manual, I want something with a little extra thought and tweak to it.

I have 4.85-8.3 cubic feet of space (internal)

I'm hoping for EXTENSION. Like LOW.
I don't have a subsonic crossover, but I need a ported box for efficiency (No space for bandpass)

So I'm looking for an tune freq of like 25 hz or so, i was thinking in a 5.5 box.

Any suggestions or modeling?

Also- 2 4" ports or one 6" port, the length doesn't really matter at all.

If you got the space try this design.Build the box to 8.6 cubic feet internal volume, one 6 inch port 10.5 inches long.That will tune it to 25hz.
