I've got a couple of push pull subs and I'm thinking they would benefit from some polyfill as the enclosure isn't that big considering it has dual drivers.
Do you think this would be beneficial for this sub design? If so how would I go about filling it? Since the driver on the bottom of the cabinet is facing up inside the cabinet I'm guessing I'd want to avoid having any polyfill on top of it.
Cheers for any help.
