Sound like you talked with the JL tech guy. I've called JL tech service twice and both times I've been switched to Barry Ober. He is an independent audio shop owner http://www.soundoctor.com. He promotes the use of outboard crossovers and happens to sell them. He doesn't have much to say in support of the use of JL's excellent onboard crossover although he doesn't dismiss them either. Very odd arrangement JL has IMHO.
