Title: 66 Super Reverb - Sounds great, what is this speaker?
Post by: LooseChange on July 10, 2011, 09:38:11 am

Can anyone tell me what kind of speaker this is?
Thanks!

Looks like a CTS basket. Alnico magnet. 16ohm. Chicago Telephone made speakers for virtually everything back then.

Hard to read the bottom line of #'s, which could give us the mfg #......are any of the other speakers easier to read?

Yup, CTS, but IMO from a speaker in the hifi line.

That was the best of the four.  It looks like the first two digits are 67.

Could be, but no speaker mfg matches 67* in the EIA/ECA database.

If it is a CTS, the back is much wider and closer to the spider than the typical CTS speakers in a Super Reverb.

there are some differences in the photo

the photo that LooseChange posted show a different magnet hold and the magnet hold is on a rounded sourface that is bigger than that shown on the other photo here http://www.mylespaul.com/forums/squawk-box/28562-mystery-speaker.html (http://www.mylespaul.com/forums/squawk-box/28562-mystery-speaker.html)

Thanks guys!
I have to say that this Super Reverb is probably the best SR I've ever heard.

The basket looks the same to me and if you take into concideration that loose changes is a 10" and the other is a 12" it would explaine why you can see more of the round mounting surface on the 12" the magnets are most likely the same size.....IMHO
