Wow! These things are massive. Picked up the 6" Aeroport at my local Rockford Fosgate dealer tonight for $35.68. These things should really make the Tumult tumultuous (sorry). These things will need a massive hole in the enclosure to install. Therein lies the problem. I build an enclosure with 1.5" walls and a 2.25" baffle and the area right around the aeroport is 1/8" thick plastic. After I installl these should fill in the gap in the baffle and the aeroport with epoxy or cement? Am I giving this way too much thought?
