I was in sound advice the other day when i put on two 13W6V2's in a sealed box and then just for fun I put on a single 13W7 and it hit so much harder and lower than the two 13W6V2's and the were running the same JL 1000/1 amp and they were both in sealed boxe's and i could not believe there would be such a differace but there was so before you go with Audiobahn who makes some of the worst sounding speakers i would look at these
or any JL's for that fact, hope i could help
