Unibox question (2 of them)

[Bent]

I'm designing a xealed box around a pair of RL-p 15 D4's. I'll be wiring for a total load of 4 ohms nominal. (driver voice coils in series, paralleled with second driver wired in series).
When entering the TSP's in Unibox, how do I know if driver the given driver specs are for v/c's in parallel or series, and when running the sim, is it then called "two drivers in series?" The specs are listed here
(I'm guessing at Re = 6.1, they are meaning in series...).
My box is approx 43" x 22" x 22" external which means 40 x 19 x 19 internal, + 14440 cu inches prior to drivers and bracing. = apprx 8.5 ft^3 before bracing and drivers.
I'm going to be conservative and guess I'll be at 7 ft^3 after building and would like to know what my system Q will be and whether utilizing my ADA-1200's L-T will be required as I'll need to plan on adding some resistors and caps...

I have a BFD-!!@$ already. (oops, shift key was stuck).

Yes 2 -4 ohm VC's wired in series, makes the resistance 6.1 ohms for a single driver. So tell the progam you're using 2- 6 ohm drivers wired in series if that's how you're going to do it.
