Im looking for SQ and mostly SPL, which one fits this? Ive read about these 2 subs for many moths but now im gonna buy one of them? So which one has better SPL but doesnt lack to much SQ?

 

out of those two options I would say the JL 13". its a great mix of both and more displacement than a 12" - more SPL

also add to your list a Arc Audio "Arc series" 12". just imagine a image dynamics sub + output!!

research online and read the reviews...
