4 VERY NICE AR3A SPEAKERS. I HAD THESE SET UP WITH A QUAD STEREO SYSTEM. THEY HAVE ALL HAVE BEEN LITELY RESTORED. THE CAPS WERE CHECKED FOR VALUES, AND IF NOT UP TO PAR, THEY WERE CHANGED WITH GOOD QUALITY REPLACEMENTS. THE POTS WERE CHECKED, AND IF NOT UP TO PAR, THEY WERE EITHER SPRAYED WITH DEOXIT CONTACT CLEANER AND/OR THE POTS WERE BYPASSED IF THE POTS STILL DIDN’T WORK GOOD ENOUGH. THE WOOFER SURROUNDS WERE REPLACED WITH QUALITY NEW SURROUNDS. ALL OF THE DRIVERS WERE CHECKED, AND ARE ALL WORKING. THE GRILL CLOTHS WERE REPLACED, OR THE ORIGINALS WERE COVERED WITH A HANDSOME BLACK ACOUSTIC FABRIC.. EACH HAS A NICE SHINY AR3A BADGE. THE CABINETS WERE ALL LITELY SANDED, AND IF NEEDED, A LITE COAT OF LEMON OIL WAS APPLIED, AND HAND RUBBED TILL A NICE SATIN SHINE WAS ACHIEVED. THESE ARE PLUG & PLAY SPEAKERS. YOU WON’T HAVE TO DO ANYTHING BUT GET THEM HOME WIRE THEM UP, AND ENJOY. I DON’T KNOW MUCH ELSE ABOUT THESE WONDERFUL SOUNDING SPEAKERS. COMES WITH SOME NICE AR3A LITERATURE AS WELL.
