They should at least start offering pre broken in speakers. Cheers

[@bradhargis2261]

The cone sanding definitely made it sound closer to the real thing! It softened the reissue up quite a bit.

Love to see you chasing tone in these experiments. Sounds great both ways. Slightly sanded seems to retain a little more bite, and the heavily sanded sounds like you got the classic recorded tone from records but as a live version. Love the playing on the jam at the end.

[@daveanderson5680]

The vintage speaker still wins my vote. I’d like to hear how the vintage speaker cones tone has changed since it was new...that’s a challenge for you Johan

[@yetanotherbassdude]

It almost feels like the Pulsonic tone is somewhere between light sanding and all the way down. The big thing that the original had was that there was still clarity. The top end was still present, but much sweeter than the reissues, and the bottom end stayed tight, whereas the all the way cone started getting a bit farty and wooly. Definitely going to try sanding a reissue to see what I can get from it, though! Cheers as always Johan for another fantastic video!

[@drewpennell8362]

I don't know, I think I personally like it better only slightly sanded and not all the way. Yes it is warmer when it's sanded all the way down, but I feel like you're sacrificing a lot of top-end.

[@jakewilliams5796]

I have always had an idea that each individual fiber that makes up the paper of a cone has a small amount of vibration from fiber to fiber, i swear i can hear the " gain " or " distortion " of an amp and the pickups more clearly through old aged cones, and in this experiment the more you sand the more clearly i can hear the " break up " sounds. More great stuff please, i love it.

[@JohanSegeborn]

Thanks Jake!

[@AmpAHolic-wn6mr]

I prefer the lightly sanded version myself. Perhaps somewhere in between would be the best of both worlds. It’s apparent the more you sand the more you change the frequency response of the speaker. Knowing exactly when to stop would be trial and error. Your definitely onto something.

[@JohanSegeborn]

Thanks

[@mgalbu]

Awesome video Johan! It really sounds very close to the original. What surprised me was that the deep sanding made the RI Lead cone sound more like the Pulsonic 55Hz cone in the video. Love these tone chasing experiments!

[@JohanSegeborn]

Thanks Alan, Glad to hear it! :-)

[@AuntAlnico4]

I remember this video @Johan Segborn A better way to do this is spray the cone with water very fine mist. A humidifier works best but when you do this to can not touch the paper as it will likely rip. But you just saturated the cone with fine moist mist and then let it dry. It should really clear up the bass and high end and the mid range should be more open as well. It's an old trick to get the thick cones off brand new speakers to be more like the vintage played in ones. Plus the pulp was mashed up finer for those old cones in the vintage speakers. These old speakers have cones that have worn thin from being used a bunch and being loaded up in the back of trucks and getting wind and rain on them at shows, it shows if you look for it.

[@anthonydratnal1870]

Hopefully Celestion can start making thinner cones on a large scale and produce a much closer Greenback reissue!

[@JohanSegeborn]

Yeah, or at least find a thicker paper with these properties. Cheers

[@thorinbane]

The problem is the longevity of the speaker at that point. Like Johan said, they need to improve the cone properties without thinning the paper too much.

[@christophergregory1205]

Hi Johan: incredible tone difference: the sanded down cone really sounded vintage, mellower: you should be permanent member of the Celestion R&D as their Einstein !! 🤣 Great vid and inspired playing ! 🤘🏻

[@silentweapon338]

Bottom Line is Celestion NEEDS to figure out how to make the current cone thinner or "rediscover" the old formula!

[@JohanSegeborn]

I’m actually pretty sure they know know how to build a speaker that sounds more or less exactly like the original. However, since the current reissues, which probably are built to a great margin, are accepted by most customers, there is no business case to introduce a better speaker. That would only undermine the sales of the current Greenback RI. What I don’t understand is why no one else introduces an authentic sounding Greenback clone.

[@brianeno608]

I feel like with the vintage vs reissues, they definitely need to find a way to get close, seems like the final pieve of the puzzle lays in the cone and the cone material and its thickness or lack there of. Thanks for doing this experiment, i could definitely not afford to lol.

[@TheChipMcDonald]

Interesting! Along these lines though, I think trying to replicate the compliance/mass of the speaker might be achieved with 1) treating the cone with a dilute HCL or H2SO4 solution to partially digest some of the cellulose - replicating aging, but then to 2) retain some of the stiffness by spraying the back with a lacquer. Furthermore the 3) breakdown of the coil glue maybe bake it? Then try 4) reducing the magnet coercivity, hit it with a hammer, or try to demagetize it with a field coil and 5) replicate aging of the surround, sand it Another thought would be could you accelerate the aging by putting the cone under intense UV (like from an old press-plate photo resist burner) ... But I think aging the spider and the dust cap would hold the most reward for effort. Making the spider lighter but stiffer,l... Or experiments with the dust cap in my "testing" makes the biggest difference...

The greenback reissue in my mini jubilee has a very nasal tone and it sounds very different from the many other greenback reissues I have experienced.

[@kevinhicks3214]

It is very unlikely that the vintage greenback sounds different because it is old. In fact it probably sounds exactly the same now as it did 50 years ago. Why do I say that? Because people today pay crazy prices for original hi-fi and studio speakers from the '50s and '60s like Tannoys, JBL and Klipsch because they sound so good . Exactly like they did when they were built. I know studio speakers include tweeters and crossovers but even so if the driver frequency response changed this much over time then old hi-fi and studio speakers would sound rubbish and be worthless. In fact the opposite is true. The difference in sound is down to materials, design and build.

[@JohanSegeborn]

Indeed, the reason vintage Greenbacks are desired is because how they sounded on the classic records of the 60s and 70s when they were new

Can you please do a seventy-eighty next? I think it's the most complained aspect of the marshall dsl40c.

Oh yeah, close, but the aggressiveness does get lost from the speaker a bit. Not really the treble per se, but the attack is softer. There is some treble lost though. I love the sanded all the way sound, but I think somewhere in between slightly sanded and all the way, you hit something big. You gotta think, those speakers get worn over time, and if you could replicate that wear, I would think with some coarse grit paper, you could replicate the sound of the speaker. Almost like relicing instruments, except this is actually useful!

[@MrJLobster]

There are a few processes that affect loosening up the fibres in the paper cone throughout it´s lifespan. 1: movement 2: humidity 3: wear off. You´ve worn off quit a bit from the surface which was a real success! I thinker around with an idea of humidity and movement. Wet the cone with warm destilled water - play it half an hour moderatly - until it dries up slowly. Repeating the process 2 or 3 times should give you the effect without to much damage to the paper. What do you think?

[@slovokia]

I wonder what would happen if you tried spraying a fixative spray on the speaker cone - would the treble increase? Another idea would be to incorporate a passive filter network that rolls off the top end into a power soak device - that way your speaker lasts longer.

[@joefarmer7727]

[@ER-yq1lc]

Very close to vintage. I wouldn't worry about VC rub as long as the spider is still in good shape. I think when a cone is less stiff certain bands and peaks can ring out better and have less dampening from the surrounding cone, less intermodulation "cone cry" and a smoother more balanced sound. Also you are slightly reducing the mms (moving mass) which will affect all the speaker parameters to a degree (in a good way).

@@JohanSegeborn When the cone is sanded you loose the outer compressed coating of the paper. Leaving the fibers of the thin cone exposed.

Hey , how about magnet swaps ? That seems like the next frontier . For example, start with a stock Celestion G-12- 100 watter and progressively go with smaller magnets. We always see the celestion catalog with all the different magnet weights or strengths, or partner with one of those companies like Eminence or Celestion to see if they could provide a 'Kit,' one speaker frame and voice coil, with several different magnet options. Seems like it would benefit them as well with exposure, while in your lab and on the youtube. Just an idea. All the pick up magnet swappers will love it ;-)

[@JohanSegeborn]

That is a great idea! Cheers

[@EdwardT9]

I wish this was easy, but the magnets are bolted onto the frame from under the spider. You Would have to recone it each time.... You could add a second magnet on top of the first held with epoxy,...that could simulate a bigger magnet. Start with a G12S and add magnets to it. You’re effectively increasing BL this way. But, Peavey did make a speaker with a bolt on magnet..but I think all the magnets are the same.

I believe it’s the same as their Heritage series Greenback speaker. Each speaker says it’s rated at 20 watts and it’s 15 ohms. I don’t have any hands on experience with an original vintage Greenback so I have no way of knowing if these EVH Celestions are close to the original. But I do know that this cabinet sounds very warm with a sweet top end and broad mids. And when they are pushed hard, it sounds incredible! Do you have any experience with the EVH Celestions?

Is position within 5mm acceptable, or is 1mm needed? And make it repeatable using a looper pedal...which is less fun but more scientific. :-). I think these sound drastically different but I like both! I bet a cab with 2 sanded and 2 stock would sound great.

That’s kind of passive aggressive isn’t it? The cab position is identical which was made sure by physical references in the room.

Sorry, I’m just curious about the effect of these things, and I can’t do these experiments. It wasn’t meant as a criticism, and reading my comment again today I agree that comes across as P-A! I should have asked it differently. :-). I thought about it a bit more and I think that you playing the riffs and not using a looper does represent exactly what a typical musician would do to measure the effects of changes they make, and a looper would remove the “feel” a player would have in the room playing live with the amp- speaker. I guess a looper or plain old signal generator would be good if doing experiments and measuring with instruments, but the final cut has to be with a real player.

Pretty profound Johan! So how does the vintage speaker achieve this timbre, does it shed paper over the years maybe? I'm totally doing this to my 4 x 12! What grit lol? 120? Guess i can experiment
