Ive got two JL 10w1v2 subs which require 0.625 cubic feet for a sealed box. My sealed box has 1.0 of cubic feet for each sub chamber of the box. Now i know poly fill makes subs think they are in a bigger box but what can i put in the box to make the subs think they are in a smaller box? Or do i even need anything, just leave each chamber empty?
