I'm not sure what question I left unasked.
The question unasked was exactly what you're posting in your above. How to deal with what I suggest, globally curtailing filtered content ported to the subwoofer.
I understand that doing what I suggest is an imperfect solution to your stated dilemma but despite it's obvious flaws, as a solution, it's the best recommendation I personally had to offer.
So, it's a filter that cuts the highs and passes the lows. Sounds a lot like an adjustable high-cut / low-pass filter. But perhaps "frequency limit potentiometer" is a more accurate term
The potentiometer globally limits the higher frequencies, reducing content for the sub to reproduce. The term I'm using best describes the action of the potentiometer, that being a frequency limit device. As I see it, the difference in this case is, the action is end use action which isn't passed off to another appliance such as is the case of the "filters" in an AVR. If this action qualifies the potentiometer as a LPF then a LPF it is. But, in this case, with nothing being passed, the added use of the term "filter," qualifies as a misnomer as nothing is being filtered or passed but instead is simply being limited or reduced and not passed, end use.
(And yes, I know, due to their esoteric needs, somebody is going try to take me to the wood pile over my above and I'm simply going continue ignoring them.)
