GM,
Hope you are doing well!
Have you ever come up with a design for the GPA 416C for MLTL?
I've seen several from you for the 416B but I know the Vas is different - suspect those designs may be to large a box!
Thanks,
Sean

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.
