FDP Forum / Fender Amps: Vintage (before 1985) / Vintage Jensen Cones?



Sep 15th, 2016 07:55 AM   Edit   Profile  

I bought Myron Lee's (he played guitar for Dick Clark) '60 Bassman. I'm trying to tell if the speakers were reconed. The Jensen frame codes (220950) are correct for original speakers, but the numbers on the cones are 4943W1 and they're very large - like ~ 3/4" tall. I'd post pics but I'm new to the forum and don't see how to do that.

The guy I bought it from said he was told they blew almost immediately back in like '61 and were reconed *then* but I'm trying to tell for certain. Also, if you experts feel they were reconed, and it was done way back then, what are the chances the cones might be nearly identical to originals?

Any help is appreciated.

I don't recall seeing numbers on cones that large on any vintage Jensen speaker. No telling what or when unless that part number means something to someone else. No matter really but it would be nice to know.

A Google search of that number yielded nothing helpful.

Thanks Hammond101 for the reply. Do you have an opinion on the criticality of the cones to the speaker tone? Seems like recone jobs just don't ever sound like the originals but I'd love opinions on that. Recone it and ruin it? or are some people able to make them sound the same?

Personally I find that vintage Jensens sound better after you re-cone them. My experience is mainly the 2 or 3 vintage Jensen C12N speakers I've reconed. They end up sound less muddy and muchy after the work out old cones are replaced.

when I bought my first blackface Twin, it came w/one blown Jensen C12n and one not.

I sent them both out to be reconed because I was certain I'd blow out that 30 year old cone sooner rather than later.

they're both still ok 20 yrs later.

I built a '57 tweed Twin clone. Tried 5 or 6 different speaker pairs in it. The best and what is now in the amp are a pair '58 Jensen P12R. They are recones, warm and marvelous.

Congrats on that amp, enjoy it!

You may never know if the new cones are exactly, in every detail, like the originals.

That said, I had Ted Weber recone some old Jensens for me and I think he reconed using the same paper that went into his Weber speakers that are modeled after Jensens. Probably as close to original as he could get at the time.

Gerald W said in one of his books that the paper used in recones is never the same as the old stuff (so therefore it has to be worse) but for all I know, the new stuff is superior and the recone may sound better, be more sensitive and handle more power (be more reliable). The old stuff isn't always better - they wanted better speakers back then and the Bassman changed to the 4x10 configuration to keep from blowing speakers.

Don't let your questions about this keep you from enjoying an awesome amp!



Fender power to the people!

If they were reconed back in'61 the chances of the cones being the same are pretty good.
All in all though, don't spend too much time and energy stressing about the cones.
Play that thing and enjoy it!
