Greenback with 1777 cone?

[Scumback Speakers]

Thanks Jim, just wanted to make sure people knew the 6402 was a slightly better (subjective btw ) and different cone from the 53's
I'm wondering if the change in the reissue cones from the first 6402's might of been a production facility change due to the high demand that started for the reissues? They opened the Czech Republic factory in 95, maybe they moved some of the English factory products there?

Well, there's plenty of room for speculation. Kurt-Mueller supplied the cones to Celestion for years, now Celestion has alternative suppliers, both in the EU and Asia, I understand. I never heard of a Czech plant, though, for either company.

Whether or not the 53H1777 is exactly the same, better or worse, than the 6402 is always subjective to the player/listener and their ears.

I have some re-issue G12M 25w speakers from Dec. 18th 2000 (18MK) which have the 53H1777 cone also. I don't remember seeing an '8' on the cone though.

Well..the Greenback were originally reissued in 1989 when marshall also reissued the jtm45 and the bluesbreaker..so not mid 90's but late 80's.

From what i've heard playing them..the 6402 cone was more like a mid 70's greenback..very prominent mids a little bit cut on bass and treble..while the 53H1777 cone that i think appeared in the late 90's has a bit more treble, bass and punch..i think a bit louder. (Infact if you remember, originally on celestion website the greenback was at 97db efficiency, then went to 98db)

If you hear a pulsonic greenback,compared to a 70's kurt mueller GB it has cleaner and less squished mids, is more open in the treble and softer bass.(think heritage g12m)
The 53H1777 Greenback reissue (the english one..not played enough the chinese) has the sonic footprint of the 70's greenback, but more bass, more treble and more kick in the mids..and i think it's a great speaker..way more versatile than the heritage that IMHO is too quiet..and under distortion doesn't compress so much..is more a speaker for clean - semiclean sound..

Celestion Marshall G12C is (sonically) a Greenback reissue but with a cut in treble..and then more visible mids..like a 40 years old speaker..

To me, I don't hear any difference between the re-issue G12M 25w speakers from Dec. 18th 2000 (18MK) which have the 53H1777 cone and the re-issue G12M 25w speakers from Sept. 4th 1996 (04JF) which have the 6402 cone that I own.

[GURU1979]

Well..i'm speaking of very very little difference..and i'm referring to a 1989 greenback so really one of the first run, and a 2002...with 13 years less of use..so maybe..

a different stamp doesnt have to mean its a different cone. they are just part numbers!

also why cant a speaker assembled in china be made from the same parts as a speaker assembled in england? one tiny detail doesnt mean the whole speaker is completely different.

Quote... 'I did have lengthy discussions about these cones with Duncan Boniface while he was still the lead speaker engineer at Celestion, though. As he related to me, the 6402 cone was an attempt by Kurt-Mueller to recreate the old Pulsonic cone tone, but fell a little short. Then they changed the pulp to make it better, but it got worse and they changed the cone # to match the date code stamps on the 102 003 cones (which had 1-52 on them BEFORE the 102 003, etc). But to make sure no one thought they were making them every week, they gave it a fictitious week code, hence the "53" since there aren't 53 weeks in a year.

also why cant a speaker assembled in china be made from the same parts as a speaker assembled in england? one tiny detail doesnt mean the whole speaker is completely different.

I can't see any reason why you couldn't make the same speaker with the same parts and the build quality to be the same? ...but the build quality 'could' also be worse? One things for certain, it won't be completely different.

Not much to add except mid 90's Wizard cabs w/6402 coned Greenbacks sound absolutely fantastic.
