Figured I'd really learn some things, by asking the astute members of this board, a comparison of these two classic microphones. Thanks in advance for your responses. Chris EDIT: Am curious in both directions. 251 vs. C12 too!  A 2024 Bump!  |

Simply put, If a Neumann U47 with the K47 capsule and VF14M tube were merged with a really good C12, you would have a Telefunken ELA M251
Or, if the two had a child, it would be the 251

Thanks! I've never had the opportunity to sing through an "original" of either the C12 or 251. But I have tried the Telefunken (repro) C12 & 251, and the Flea C12. My "wow" was the Flea C12 (they were very close though), but haven't A/B'd them directly, at the same time. I have done a bit of background reading on some other threads with other knowledgeable folks like J.J. Blair, Klaus, et al. (just enough learning to be mildly dangerous!) Chris |

Isn’t a 251 simply a c12 with a few extra resisters to roll off the top end? I never understand why people think these mikes are so different they aren’t actually ?

The ELAM 251 has a 100 pF capacitor (not resistors) to tame the high end a little bit. They have slightly different capsules, different circuits (tube bias, pattern selection, coupling, etc), different head grilles. It all adds up to being a different microphone. Kind of like the Jaguar vs the Jazzmaster to use a Fender guitar metaphor. David Bock has a good technical post on one of the pro forums about these mics. I can find it if anyone is interested. |

Yeah I don't find them to be terribly different. C12 has more top end which makes it seem a little more sparkly with the right tube.
C12 is not a great choice for singers with a lot of shrillness to their voice, while a 251 is a bit better in this regard.

@monkey I thought originally a marketing or distribution contract lapsed so that the original c12 could no longer be supplied, so very minor changes were made and the new mike was called the 251? Later on they may have made further changes but not originally ?
I know that I have read this was the case ?

Later on they may have made further changes but not originally ? I know that I have read this was the case ? I think the story is something like this: Neumann was providing U47 to Telefunken. VF14 tubes stop being made so the U47 and U48 are discontinued. Telefunken needs a new flagship microphone. AKG is contracted to come up with something with a current production tube and they come up with the ELA M251, which of course is the "Telefunken 251." Not the AKG 251. It was something like starting with the AKG C12 design and pushing it more in the direction of the U47 to fill that gap. Hence the bigger body, more bass response, etc. |

They use different capsules? I think David Bock said the 251 capsule was "tuned for a little more low end." Apologies for the paraphrase. They are both CK-12 style capsules, however. Maybe if Tim Campbell sees this thread he can give some expert commentary. |

That's great info. I've had the chance to work with a 251 and a U48 but never a C12. I think the 251 was my favorite, though I own a Wunder CM7GTS/M7. I wish I had the money to get one, but alas, my daughter needs to finish her masters degree... the sacrifices of a parent. :-)

Great info-Thanks! Based on it, I wouldn't be surprised if the capsule Tim C. designed for the Flea C12, is somewhat "darker" than the typical/weighted average AKG C12. The Flea C12 "lingered in my mind", long after singing through it at Vintage King (L.A.)!
If it was at all "too bright/spitty/overly sibilant", I would have noticed it (my voice has a strong 6.5 KHz peak).

I find the C12 a little less "etched" out and hyper shaped sounding, compared to the ELAM251. The 251 shoots the sound out of the speakers like a rocket. While the C12 just sounds like money flying out of the speakers.

We have a Bock 251 and a Matador/Chunger DIY C12 with a Tim Campbell C12 capsule and fitted with a NOS GE tube.
When I first used the Bock 251 I was surprised just how much low end it had which can make it seem subjectively darker than you think especially when close mixing due to its proximity effect.
The low end also goes down very low as it is quite sensitive to distant traffic rumble such as large trucks.
The Bock has the biggest output transformer I've seen in a mic.
In comparison the DIY C12 sounds brighter than the Bock.

I suppose that fits with what you said. I wish I have heard one but only on records. |

Been over 5 years! Further thoughts? Including the various "Inspired By's" (I personally prefer that to the moniker "Clones") So we could expand this out to C12 Styles vs. 251 Styles. Warmest Regards Chris |
