Celestion G12M-70

Re: Celestion G12M-70

I always hated the G12M70's back in the day. I even like the G12T75s or the V30s much better. An ice pick in in the ear spike and rather sterile overall is how I remember them.
 
Re: Celestion G12M-70

My jcm800 has 2 stock G12M-70's in it. I havent had a chance to really crank the MV yet, but the speakers sound pretty bright to me so far. But I dont wanna really judge them before I crank it. Ive heard a lot of ppl say they dont like them though
 
Re: Celestion G12M-70

The G12M-70 is fairly mid-deficient. Likely one of my least favorite Celestions. Still not a totally horrible speaker though, depending on the application.

But, you never know what it will mix well with. Come to think of it, it may mix well with a CL80.

It is always worth keeping one around for testing. Never rule anything out.
 
Re: Celestion G12M-70

i had a quad of g12m70s back when i thought yo9u needed a big amp. yes the g12t75s sounded fatter.
 
Re: Celestion G12M-70

I don't hear anything spikey about the G12M70. To my ears the tone is quite the opposite: bland and uninteresting. They're a Celestion utterly lacking in personality or character compared to most Celestions. I use Celestion 12's in all of my amps...but not that one.
 
Re: Celestion G12M-70

Well, this isn't very encouraging at all.

There isnt much of anything to be encouraged about the G12m-70. I agree whole heartedly with the its a bland and unremarkable speaker sentiments. I cant think of a situation where I wouldnt prefer something else over it.
 
Re: Celestion G12M-70

I'll make this simple... IMO the Celestion G12M-70 is the WORST speaker Celestion ever made ! I had a pair in a SF Twin. The amp was either too Bright ,Or Mud. And I couldn't dial the bright out w/o MUD! I got so pissed off w/t the amp that I took (what I though where my great Celestion's) out of the amp,then put them back in the 2x12 cab I took them from. Then gave the amp to my Brother-in-Law. He immediately put a pair of EV SRO's in the Twin,And it sounded GREAT!:wrf: Fast forward 5 years. I just finished building my 2204 Marshall clone,And set it atop the G12M-70 loaded 2x12.. DEJA VU all over again !:11:

Re: Celestion G12M-70

You want us to tell you the truth don't ya?

Lew: perhaps spike isn't isn't the best term to describe the icey brightness I hear in them, but I quite agree they just don't have tone.

Oh yeah, definitely. Don't take that the wrong way. I'm immensely grateful for all of you and the help and knowledge you've given me on this and many other topics.

Here's to y'all. :beerchug:

I only say it's discouraging because I have one that came stock in my AOR combo. It's an amp that I love and I really dig the sound out of it...but there's always been a little something that I couldn't quite put my finger on. Something very similar to what KMC said about either being too bright or too muddy. That sounded very familiar.

The truth is that I never considered that the problem could be the speaker. I don't know much about speakers so I saw the Celestion name on it and just kinda assumed that it was awesome. I realised that was a little naive so I posted this question and now I'm thinking I might need to invest in another speaker some time soon. :banghead:

Does anyone think that it would be worth pairing it up with another speaker? Or would it be better to just sell it and get something completely different?

Thanks to everyone for taking the time to help me. :flowers1:
 
Re: Celestion G12M-70

so really this is good news man! With a new speaker your fave amp will sound even better! So really the question is....what would you like to change? More mids, more bass, more efficiency, scoopier sound, more vintage? The world is your oyster!

They don't have much crunch...not to my ears. I remember them sounding to smooth for my tastes but it's been about thirty years or more. Had a set of four of them in a Marshall cab that I used to drive with a '71 Marshall 50 watt head - a 1987 model. I got rid of them pretty quickly and replaced them with Greenback 25's. The result was a much crunchier, more classic Marshall tone.

I remember when Celestion came out with them in the late 70's or so and a salesman telling me that they were good for warming up and thickening up the tone of a bright amplifier like a Twin Reverb. Don't know if that's true or not.

But they were not what I was looking for. These days I use the G12H30 (the Jimi Hendrix speaker) or the G1265 (the Robben Ford speaker). I like, but don't use, the Vintage 30 too, but I much prefer it in a sealed speaker cab. It's to bright in an open back combo amp.

If you more or less like your amp but think you could squeeze a bit more from it I'd recommend a speaker change. You can really alter the voice of your amp by swapping out the speakers . . . similar to pickup swapping.
 
Re: Celestion G12M-70

Kam, is this a 1x12 or a 2x12, a combo or a cab, open back or closed back, speaker situation?

It's a 1x12 combo with a closed back. The back is removable, of course, but I tend to like it better with it on.

If you've noticed my other thread lurking about this room then you'll know that I'm having a few problems with the amp anyway, and until I get that fixed (hopefully quickly and easily with a tube swap) a new speaker isn't my top priority. I really like this amp and I'd really like to get it back to the best it can be after not using it for so long.

Once the problem's sorted then a full retube is in order. After that, I was actually thinking about getting an external 1x12 to join the 12" in the combo, or possibly getting an external 2x12 and disconnecting the internal speaker, though if I do that then I'll probably end up ordering it half-loaded and swapping the G12M-70 into one of the speaker spots on the cab...at least until I can afford a different one. At the minute I'm leaning towards going the 2x12" route because I think it'll prove more useful to me in the long run if I ever get another head.

I'd really like to squeeze a bit more warmth and vitality out of it. I tend to like smoother high-gain sounds and fat, warm cleans. My amp itself has almost too much low-end so I don't want a really bassy speaker, I don't think. I do tend to like sounds that are quite low-mid heavy though. As I said, my amp has a tonne of low-end and it's not the tightest thing in the world so tightening it up might be a good thing, but I'm not a metal player so I don't need super-tight chugga-chugga sounds. I like a bit of sag and flubbiness in my rhythm sounds.

Sorry for the long, aimless post, guys. I'm pretty much just thinking out loud through my fingers here. This whole plan has been forming loosely over the last couple of days so I still don't entirely know what I want, really.

Re: Celestion G12M-70

In that case the G12-65 would be a good speaker if you stick to the 1x12. In a 2x12 format I think you would like the G12H30 mixed with another speaker, or two G12H30's.

Good luck getting your amp sorted out.
 
Re: Celestion G12M-70

bought 1 in 1990. never was that great. blew the voice coil in mid 90's had it reconed, doped what ever by a place in a chicago suburb for $35 !! It is great now. I have quite a few different speakers some are still in box & unused, but I hang on to that G12-70. Because I got lucky with it. It has always gone through a 1 by 12 openback tube combo.
