My first serious speaker in the mid 70s. Bought second hand, used with a Pioneer SA 7300, which drove them well for my domestic use.
Having also had AR2ax, AR16 and AR6, I must say that the unassuming, pleasant and coherent voice of the 4x was, in retrospect, my preferred one.
I now have another pair, very old, but it still sounds as good as I remember. Modern designs offer much more, of course, but a pair of these in good health can really make music.
I tried them with a Naim Nait 3 and the match was very very enjoyable. No very deep bass, but balance and good timbres. Nice speakers.

re: AR-4X

For their size, they really are very sweet. My pair has been recapped, controls cleaned, and surrounds have been doped with Vintage AR goop, so are back to original specs. Used in a small room on the floor with felt pads on their bottoms. Daily driver and so pleasing!
