Hey everyone, new member here. My dad gave me his SDA CRS+ recently. One of them sounds great, the other barely makes any sound at all. I remember he had that problem shortly after he bought them way back in the late 80's, and the store he bought them from merely replaced the tweeter. I'm thinking the problem lies with the crossover, which I believe is the BE1807-B on this particular speaker. Any idea where I can source this? I've been looking and looking, and have found places for modding the speakers, but I just want to get the thing working correctly. Any help you all can give is greatly appreciated.
