Any ideas folks? 10" alnico's, magnet stamp not so legible.
The basket is as this CTS.( Photo is from Reverb.com ) If you can see 137 somewhere that is the source code for CTS
Probably intended to used as a woofer in a old stereo because of the large reinforced surround.
With that edge and all that dope a bass speaker, perhaps a Utah from an early bassman??? Although the basket sure does look CTS.
Google "EIA Codes" to find a list of 3 digit prefixes.
That's a crazy amount of cone dope!!
"that edge and all that dope a bass speaker"
Okay, thanks, I was in a rush to get off to band rehersals and saw them briefly on E-Bay before posting here and rushing off. But now i'm back, and have checked them out better, and yes, I'd agree that they are CTS, probably from the mid sixties to seventies, and probably with a recone judging by the smooth pressed cone, large dust-cap, and heavy dopeing.
Anyway...I put in a "why not" bid, now get back to see I have purchased two of them for $10 ( $5 under my maximum bid ) $25 including postage. So not a bad deal even if I do have to do a recone job on them. I will try them out how they are now....one never knows.
Otherwise....anyone suggest a good recone kit supplier for CTS 064121 speakers ?
The soundspeakerrepair.com CTS-064121-Recone-Kit
doesn't look to bad, half the job is pre-done....which can be good, or not. I'd prefer a not preassembled kit. Getting two of these shipped over here would set me back $200
Otherwise the Speaker Exchange cts-064121-recone-kit
would set me back $100 and comes with alternative hight spiders, so these maybe the way to go......are there cone kits any good ?
Hopefully they sound good how they are, or, has anyone ever try removing excess dope? Sometimes it will swell and soften-up with a bit of water, then one could carefully scape back...maybe...I've never tried it.
I have a brown frame CTS 10” that I assume was a pull from a super reverb. That thing sounds great! Good luck with these.
The fam had a 1970's Magnavox stereo set, with bookshelf speakers that looked a lot like those, and the heavy doping. I remember the spider was larger that typical.
The magnet on this old ad is wider than the OP. Not sure his is 60W.
True, but the CTS 064121 that Fender used was the same size as the ones in the OP. It maybe that the advertisers drawing was slightly exagerated....wouldnn't be the first time.
But then again, biger magnet versions did exsist, such as these, a 32 Ohm version, and this 8 Ohm stereo useage one that has a cone that looks like mine.
Rickenbacker used 8 X 4 Ohm speakers in some of their cabs I believe.
I haven't seen a big magnet version in a Fender yet... but I will keep looking.
