This listing is for a single (1) Sony 1-502-935-11 4" midrange speaker, removed from a pair of SS-U55 speakers I have parted out. I have 2 available at the start of the listing. IF YOU WANT BOTH, ENTER QTY. 2 AT CHECKOUT.
 Both were tested with music prior to removal & are in very good  working condition.
 Impedance is 8 ohms & DCR = 6.4 each.
 The baskets measure 4 3/4" o.d. & 5 7/16" ear to ear on the diagonal.
