So I pulled the offending woofer and it is defiantly the woofer that is buzzing. When i gently push the cone in I can hear scraping sounds. Putting it on the ohm meter reveals 7.1 ohms. Also I was incorrect, looking at my notes, it appears last time I replaced the upper woofer for buzzing, this time its the lower (on the same cabinet) While I had it open, I checked the cabinet for any loose / buzzing along the back and it seems solid. I also checked that the metal screen was still attached inside the center magnet hole of the woofer and it was. I dont know why OEM woofers went bad in the same way within a year or so, and like I said I have a different amp now, so Im kinda thinking the crossover may be causing it? Although when I talked to Bob Crites on the phone he didnt think it was likely, but I ordered a crossover rebuild kit anyway and a pair of replacement / upgraded tweeter diaphragms... has anyone else had experience with these? Seemed like a reasonable price so why not. Anyway once I rebuild the crossovers, ill replace the buzzing woofer with my spare one and report back. Any chance I could repairing two buzzing woofers?

I can check again, but replacing the driver fixed it last time this happened, and it is definitely only coming from one of the four drivers. Ill remove the speaker as you suggested and throw it on the ohm meter. I do push them hard at times, one of the reasons I love these speakers.

Im new here, but this looks like a great community, thanks in advance for helping me out. The first time I heard the buzz was about two weeks after I bought them in 1994. I returned them for repair to the store at that time. I didnt hear the buzz again until 2016, it was only in the lower woofer of one speaker. I was able to find replacement OEM speakers and I bought two at that time. I replaced the buzzing woofer and I was up and rocking again. However... tonight I heard it again and my heart sank.. same speaker, same buzz (Especially during Hammond B3 parts for some reason). Im wondering if it could be the crossover? I recently upgraded from my Yamaha receiver circa 1994 to a Denon just about four months ago, so I don't think it is amp related. Should I try to repair or replace the crossover? Im leery of using my only other good spare because I think it may happen again. If I replace the crossover, are there any recommendations? Thanks again, Barcade
