I'd like to get this cab to 4 ohms so maybe the Eminence Delta 12B(ported only?)? Anybody able to help me with the port specs for these?

The Deltalite 2512s seem to be popular for a sealed V4 cab but can't get four of them to 4 ohms.

Beta 12s want to have at least 3.5 cu ft each; you have half that. The Delta Pro 12 is probably your best bet. You need a total of eight 4" diameter ducts nine inches long, two per driver. Four ohms is going to be a problem.

No reason why not. It's not like you'll need an extension cab.

So I'm assuming a sealed option is nil due to lack of box volume?

Sensitivity and output. Sealed will cost you 3dB of sensitivity and 6dB of maximum output. It offers no advantages.
