Just a follow up comment about this project...About six months after I finished this repair, I got a call from the church where this speaker is used. They said the speaker had suddenly started distorting. I happened to be nearby and dropped around to test it in-situ. Sure enough, the speaker was distorting. I took it back to my shop and checked it out and found that the driver (speaker) that I had replaced was the culprit. I did a test of the cone movement by carefully depressing the cone with a thumb on either side of the voice coil. I could hear, and feel, the voice coil rubbing on the magnet. Something had changed in the geometry of the cone and coil. I checked the other drivers and they all moved smoothly. When signal was applied to the faulty speaker, the rubbing against the magnet caused distortion. I contacted Bose and they are sending out a new driver. This is something I've never seen before, and the Bose tech said it was very unusual as well. I have no idea what caused this. If you have ideas, let me know. I haven't received the driver yet but will update this when I have it installed...
Hi I have Bose 501 series V floorstanding speakers that I bought in 2001 and never had any problems with them yet like foam rot that hasn't happened yet amazing to say! It probably wouldn't hurt to recap the crossovers but I don't know how to get to them at this time! So anyway I enjoyed the video!
Thanks! The crossovers are somewhat hard to get at. As I mentioned in the video, the wiring inside the cabinet is solid core so you have to be a bit careful that you don't bend it too many times or it will break off. There is a lot of foam inside the cabinet to move around to get at the crossover as well.
