Mesa Celestion Vintage 30 70 watt

[Golden1984]

Hello.

I lately noticed huge differences in sound of each of speakers in my recto 4x12 cabinet. I use Shure sm57 and isolation cabinet to recording by the way.
I bought it used so I checked impedance of all speakers and they are 4,5-5,5 ohm.
"8 ohm" speakers should be around 6,5 ohm. I think they could be overloaded by previous owner and this is the reason of sonic difference between all of them. 2 speakers sound better, but only one seems to be good enough for recordings, another pair sounds like a totally different model of speaker.
I suspect that exchanging of speaker cone, etc cannot guarantee rally of sound.
Mesa uses special 70 watt version of the speaker.
Is it possible to buy new 70 watt v30?
On Mesa/Boogie website I found only 60 watt version, maybe it`s mistake?
Is there a really huge sonic difference between stock and Mesa/Boogie`s Vintage 30?

Thanks, Peter

According to Mesa it's the same speaker. They updated their literature to read 60w so that it was consistent with what Celestion was publishing on their website.

There is a difference. Off the shelf V30s are generally brighter than Mesa's.

from what I read... some manufactures like mesa n marshall spec'ed out their cabs loaded with v30s at 70w per speaker though being the same speaker. There are also others who say that the older v30s had a bigger voice coil that was capable of handling 70wtts. In general, their the same. A new v30 will sound a whole lot different that a broken in on. The broken in ones sound warmer and smooths out the highs. New v30s no broken in yet are generally more higher pitch.

It could be that a speaker or two messed up and was replaced.
