My RCA C9-4
#12

I removed the speaker from the cabinet last night after driving back from Philco Mike's with the new ( to me ) cabinet for my Scott 800B radio / phono. It was about 300 miles total there and back. When I got home I pretty much just wanted to relax, but I saw the speaker still in the cabinet of the RCA so I decided to at least remove that so I could get on with fiurther work once my tube order comes in. I was very pleased that the removal went smoothly. The cone didn't stick at all or need to be coaxed off with a spatula.

ATTENTION NEW GUYS !!! That is something I learned the hard way, and had to re-cone a speaker because of it !. Sometimes your original speaker will stick to the mounting board. If you remove the nuts from the retaining screws, and just pull on the speaker, you can rip the cone out ! It pays to be very gentle when first seeing if it is stuck after the nuts are off. If it is, a thin spatula inserted between the front edge of the speaker and the mounting board, then gently and carefully worked around the circumference can save you a great deal of misery. Be careful though not to insert it too far and stab the cone with the spatula, just work the edge.

So, now things are on hold for a few days with the RCA. Later this afternoon a couple of my buddies are coming by to help me wrestle the new cabinet for my Scott into my shed where it can sit until I get around to it.
