Ok I get the idea now...

Took a peek and removed the bolt and two washers. I did not see any play available whatsoever in the speaker-spider assembly. I have seen some speakers of this Philco style have the cone loose from the frame and held in by screws. This one the cone is glues all the way around the frame.

I am 99% sure my issue is probably some light debris in there. I turned it upside down and moved the speaker in and out while that spider bolt was loose. Then played it a while LOUD upside down as well. Seemed to help some so I reinstalled the bolt-washers. Did not feel the rub really anymore but the buzz on this is only on occasion on really loud low bass frequencies.

Since the speaker is out I left it play at about 3/4 volume on a strong station speaker face down on some thick shims to keep it off the table. Figured it might help work any debris out by doing that. Will see what happens.
