    Depends on if you're upwind or downwind.

    Wouldn't they have to suck to? Otherwise they would soon run out of air in the cabinet to blow. :)

    To be honest, I'm afraid I don't know. I am not an expert in ports, bungholes, and orifices.

    We need a subject matter expert, maybe Jimmy? @Viking64

    Just out of curiosity what speaker design equations for PR builds are you using? Not much is known about the voice coils and magnets in the Polk PR's 🤣

    But seriously, I think you might be able to calculate piston area of the cone and you might be able to measure compliance with a dial indicator and some fishing split shot weights or the like. Are you looking to calculate Vas?
