I guess what I'm wondering is how this particular speaker will react to being in a sealed enclosure that's about 65% of the recommended size. Will the install limitations keep me from taking advantage of the bigger speaker to the point where I would be better off to use the smaller speaker? Help me choose. Option 1: IXL 18.4 on 750 watts in 3 cubic feet (65% of recommended enclosure volume). VS Option 2: JL 12w6v2 on 1150 watts in 1.25 cubic feet (100% of recommended enclosure volume).
