Just a curious question here, I think its purely opinions related. In a HT system, some of you know what I'm running (7b's as mains, my frankinPolk as center and 4's as surrounds). What setting would you recommend, for movie watching? Large or Small? If small, would you all recommend 80hz xover or 60hz. This question could not only apply for movie watching but with use of a sub for music as well? Just was curious with some of you all's settings when using the vintage equipment. Seems like small setting would prolong the life of the speakers, or would it?
