i have inherited a set of these speakers from my father, and while awaiting the rest of his stereo equipment, i have hooked them up to a theater system in my dining room. in the interest of modernizing my own speakers, I have taken some photos and I was hoping for a few pointers. I have never done any work of this sort, and any help provided would be very much appreciated. the crossover seems pretty basic. do any of you gentlemen have suggestions for replacement drivers? i'm interested in replacing the woofers at least, but I would like to replace the mids as well.
