Another yellow 82!
I am pretty sure that it is a speaker bracket that is designed to hold the driver in three places. If you secure the driver with just an "L" bracket, there is a lot of vibration potential and that was a frequent breakage spot. Our shop policy was to make sure that there were at least three points of attachment when using this D-60 speakers. When using a regular bracket we needed to get at least one screw into the cone with a fender washer to keep the vibration to a minimum.
