Currently have JBL GTO 607c's running to my Alpine 4 channel amp and am not impressed with these speakers in terms of the midbass they produce. I heard a friends setup today with JL XR650-CSi 6.5" speakers and they pounded. Would this be a considerable upgrade and would it be worth the cash to do the swap? Thanks a lot.
