What about the dcons? Would they sound better? they will work in .75, also they are shallows so they have a lot of breathing roomIf you want to seal up the port you could use the GTO 1014's they will work well in .7 sealed with the GTO751ez , but they are not slim subwoofers you would have to make sure they fit as far as mounting depth
I see you have incriminators, Im thinking about those, how do they preform?I have no personal experience with the Dcon only reputation and I have heard several Dcon setups ported ,(Which sounded great btw) but I have yet to build or hear a sealed or 4th order Dcon setup to give you an honest comparison sorry
