Bob, I'm dumb on this stuff but I would think with the spider attached with the voice coil in place (I don't see that in the picture) that would determine if you needed any fiber ring around the speaker frame to adjust height of the cone. I always wondered if the replacing of the screw to hold the spider down in place was accurate enough to properly center the voice coil. That screw hole must be very close to the size of the screw going through it to not allow any adjustment. Just thinking about why I'm afraid to do it! No little tiny spacers required when tightening down the spider?
Still watching and enjoying. Thanks.
