Not being too adventurous, I ordered an in- kind speaker replacement from ggg. I don't know if speaker magnets lose strength over time, but the new one definitely had a stronger magnet! Here's a side by side with the new one installed.
And since we are dealing with a speaker replacement here's an obligatory how-does-it-sound? clip.
This was with the sound turned way down.
As long as the tender was open she got a replacement battery. Next up is some lube for the gears, four new traction tires and she'll be good to go for another million miles��
(edit - in all honesty at first it was dead quite, and I thought I somehow fried the new speaker while soldering the leads. That's when I remembered it was still unplugged inside the shell!)
