I think that the L7's would be louder.. Given the right power, and a proper sealed enclosure the 12L7's sealed would for sure get as loud or louder than an xxx 15" ported. They wouldn't be as deep, but the output would be very close if not better.
I have great respect for the L7, and have learned to never underestimate them, because they are fu*king loud as hell when you know how to work with them.
And, i also have great respect for the XXX.. The xxx would sound way better than the solos, get low, and it would be loud as hell. But if output was all that you were after i'd get a 15 L7 and give it 1500 watts and port it.. It's impressive to say the least.
