Up for sale is a very rare AR-3 mid-range driver. This is an earlier version of AR-3 mid-range driver. This AR-3 mid-range is made of huge alnico driver and it’s very heavy. Connected AAA with battery and produces sound. That’s all I can do for testing. Based on my test this driver appears in proper working condition; however, no guarantee. Please review photos closely as they are part of description. What you see is exactly what you get. No return is accepted.
