I am running a 2 way active system and right now I am using my coaxial infinity kappa 6 1/2 inch speakers as my midbass and well as a whole the system sounds alright I guess but I want to get some dedicated mid bass drivers no more than 7 inches, that handle everything upto like 2khz. Would getting these be an upgrade http://www.partsexpress.com/pe/pshowdetl.cfm?&Partnumber=295-374 ? they are really cheap and I am worried that they might not be as good since techincally the kappas were more, but I guess I should judge it by its price. You guys have any other recommendations?
