As always.. it´s a matter of taste. Personally I´m not a big fan of 4x12s.. an open back 1x12 or 2x12 suit me best, less phase issues, bigger open sound..
You can try my IR I attached below. Pair it to the 1x12 EMI OPEN BACK (JM) for extra "in the room" feel. Set mic to NONE on both and let me know
