Rickresource Rickenbacker Forum

Surprised by the 'rip' in this cone. Most likely an Eminence 12", as found in a (1980?) Rickenbacker TR25 guitar combo.

Initially thought it was damaged, but more likely seems to be intentional/by-construction, since the paper is overlapping ('rips' are offset front vs back).

First time I see it like this. Always thought speaker-cones were pressed, not folded & glued into a funnel.

FWIW...
(Yep, dustcap bottom left, dust top left )

I've never seen a loudspeaker cone constructed in that way before, either - and I've had speakers of all vintages, dating back to the 1930s. As you say, though: it certainly doesn't look like a repair. Bizarre!

Hi,

It's all trivia & fwiw, but I've definitely never seen it like this before.

It seems to be the stock TR25 12"speaker (with codes I've seen mentioned for the TR25 here before: SP122016G) so likely it must have crossed the eye of various other TR25 owners as well.

At least assuming they unmounted the speaker to give it and the cab a proper cleaning. Alternatively, pulling off the velcro-attached speakergrill would already show it.

If it's not common though, then possibly it's a reconed Eminence, and everything is possible.

Just for the sake of trivia I'll show it to a friend as well, who has seen at least as many instrument speaker cones as I have.

While instrument speakers will be more forgiving than those for hi-fi, much thought seems to go into design of the former, to say the least (I recall an article in... SoundOnsound?, from a Celestion-designer).
Can well imagine that overlap-section has a drastic impact on the vibration pattern of this speaker. Who knows it's both cheaper & beneficial ....

Bye!

BTW, from your signature:
Epiphone Jack Casady --> yummie
Ovation Magnum 1 --> on wishlist
Peavey TB-Raxx --> nice to see this one being mentioned

I have a couple of vintage Jensens with seamed cones, and Weber makes a few vintage-style models with them for extra authenticity.

Look closely: https://tedweber.com/12a125/

So it is a thing.

Nice, indeed same kind!

Thanks for posting, and nice to learn the 'official' description for it (seamed).

Historically, many drivers, especially those for mid-grade "hi-fi" (or not) home audio gear (before stereo), had the paper cones that had the biased seam that only had to handle about 5 to 20 watts. It's not that rare, it's just not how anything is made anymore.

Thanks for the reply, interesting to hear. Hadn't seen like this before, but sure makes sense.
Trying to recall which combination of 'brands' and 'old speakers' I may have seen the most, possibly mostly Celestions, no idea if they have been using it.

OK nice, 'riddle' solved, thanks all!
