:) John: Yes, K=AlNiCo, E=Ferrite, The E series handle more power, but some musicians prefer K's, it has been discussed here amply, and producing against re-producing sound is a matter of personal taste, these lines of speakers are lots of times overdriven on purpose (against JBL´s recommendation), but what counts is if You like it, E's have about 50% more power handling.
