When it comes to 15" extended range drivers I was wondering if JBL has anything as flat in the mid-band region(100 hz-4 khz) as the Eminence Kappa pro 15. I've used various E series speakers over the years and have always been impressed by their efficiency-- I've found the E-120 to be an extremly Loud 12" speaker as well as its slightly larger brother the E-130, but as far as efficient and "flat" PA mains are concerned the JBLs in the E-series are not exactly suitable in this role without a good deal of Eq, of course I understand that JBL has many PA type speakers (as opposed to instrument) out there. The problem is that while its easy to obtain Eminence frequency response graphs (they are in their catalog) its not as easy with the various JBL line--specifically 15". Anyway, Thanks for any help I might get. PS--in addition to response, are there any JBL 15" speakers that handle as much power with efficiency in the mid band area as the Eminence.
