This speaker is for sale in a city south of me. The ID badge is missing and I can't identify the exact model number. The replacement cone has a number that matches that used for 416/515 speakers, but, as you can see, it is a rear-vented speaker. Seems it would be a musical instrument speaker, but which model number?

Suggestions from another site indicate that it might be a 921.
Too much magnet/motor, i think.Quote:

It's a series II 421 with the frame poorly sprayed charcoal. Look closely at the OP's pic of the frame. That would be the crappiest charcoal paint i ever saw from Altec, and the first with white paint under it.
I can't figure out why someone would go to all the work of repainting the frame. Masking everything off would be a royal PIA. Not doubting you Bowtie, you already forgot more about Altecs than I'll ever know.

Most likely done at the time of re-cone. I'm not sure why they did it on this one, but i suspect so as to represent it as something it's not.Quote:

After you collect a couple dead 604C, D or E, you only need mask the front plates of both the HF and LF, then spray the whole deal charcoal hammertone prior to sending to GPA for re-coning and re-charging. You can get 604-8G foilcals on ebay. If you do a good job nobody will ever know.
There are at least a few pairs out there, as well as some 515B's whose motors have been moved to large frames.
I think its cool how you can take different frames and motors and make something. Ever since Bowtie explained this to me it has changed the way I look a damaged drivers.
Like if I could find a 15" 515b with a damaged frame, I could slap a 16" 421 frame on it and make it a 16" 515b. To match the orphan I have.
You can get blown 16" 421's for dirt cheap. I picked up a pair for 20$ once.
The sad thing is, as woofers they sound pretty good. I had a pair of 421H that Gordon W reconed as franken416's. I used them in my A7 cabs and they sounded pretty damn good.
On mix and match. A lot of us have 421s, high or low versions. I wonder if a surround change could extend the LF into subwoofer territory?
