All things considered, doing OK, at least no one I know has been struck down by Covid other than some I know on the various forums, though all were older than me, in failing health and contracted it in the hospice or hospital they were at.
Most of my friends, relatives thought me nuts to continue to save as much as I could in retirement to maybe be able to afford quality in-home assisted care or similar instead of blowing it on trips, new car[s]/audio-video system/whatever; not now...........every time they cough from the smog/pollen they 'durn' near turn gray in terror that Medicare will kill them from crowding/whatever.
Anyway, no, folks mostly build 846B, M19 with these, but I basically do the same alignment for a given driver type, so you can take one of the others, use the pioneer's net volume [Vb] = Vas/1.44 tuned to actual Fs.
Of course Vas should be measured, but drivers known to be high Vas require big enough cabs that it's not critical if you use published. If driven with a high output impedance, then Vb = Vas.
Vent area typically needs to be at least Sd/3 for ducted port and for regular reflex, I'd have to use a program to calc whatever you build or you can do it the old DIY way like so many of us did way back when.
