Warn Sound Capacitor

I.own a new pair of 4367 horn speakers from JBL. Overall, they sound good, but the horn can dominate especially when it comes to the elevated human voice..that is overbearing, loud, and shouty  Can these components mentioned above tailor the sound so to retain most of the speakers attributes, yet attenuate the shoutiness? Are there any aftermarket products, such as crossovers that can be simply swapped to possibly fix problem?
Thanks for letting me horn in,..just not sure where to turn to effectively,  easily, and practically address this issue with the speakers. Thank you.

I suggest the Miflex KPAL series. If those are a bit too spendy, I would suggest sticking with a film and foil type, and staying away from metallized polypropylenes. The construction is much better.
