okay so I have 2 12" kicker cvr's ported on a eD nine.1 right now. If I wanted to switch to a single 15" Fi bl, what would be the general differences in sound? Do you agree that more cone area is more sound or do think that the spl will remain similar because its the same amp? I know the sq should be better with any respectable brand other than kicker (not a known sq brand) so thats why im wondering. And yes the BL would be ported as well.
