To be able to find a direct "bolt in" replacement mid range driver for a 40 year old speaker was great. The sound is like the original. The mounting plate is much thinner than original and was not & cannot be countersunk to receive the original screws. I had some round head screws that I painted flat black. So not totally original but for my purposes fine. The original driver has front mounted connections and this replacement had rear mounted so I drilled a hole run wire through the cabinet face to the front mounted connector block. Filled the hole with hot glue. Taped over the wires with black tape and it looked sort of original. Again for my purposes fine, as I listen to the speakers and keep a grill cover on them.

The speakers sound very good - much clearer than the original ones that they replaced in my AR-3A's. Mounting them required moving the position of the mounting holes - the ones on the new speakers were smaller than the original bolts, and closer to the center. Not too difficult to change as the material is fairly soft plastic. Overall I'm glad I made the change!
