Quarantined with my wife for a week? I'd need Prozac and vodka, lots of it.

Started painting one of the Jacks, found some time to make the phase plug and spacer yesterday. Mental note: never promise your wife to do something whenever you will have enough time to do it, she will remember...

I would combine two Jacks 112: one with and one without the crossfiring blended array (for bass cab). Should I just use the wiring plans for the Jack 212. I would wire them parallel to get an 4 Ohm resitance, my amp delivers 700W at 4 Ohm.... Would I need different wiring if I use the one with blended array as a PA speaker? I suppose this one could have two different inputs then, one for use as part of a bass cab, one for use as PA...

Do you mean I just make them with the same low pass filter and add a high pass filter to the one with the blended array, as per the plans/jack 112? Then connect them with a speaker cable so that they are running parallel? This is not really my forte, hence my question....

That's correct. It's how I recommend doing a scalable bass rig, as one tweeter array in the upper cab has plenty of highs to keep up with the additional low and mid output from the bottom cab.
