I have restored a pair of L-96s, but the midrange drivers appear to have some distortion, and i have other mids around from other pair of speakers and would like some suggestiions: speakers avail are: L-166, L-100, P-30, L-65, L-50and L110. I am not keen of swapping out for obvious reasons, but want the L-96s to really sound real good if possibe until i can get the original ones repaired....any ideas.....thanks.
