Lew you have an AC-30 TOO??? not fair at all!

I've always wondered about the blues so since you have speaker experience I'm going to hijack the thread temporarily.

fftopic: What differences do YOU hear in ceramic an alnico speakers and the webers that use both?
Luke
I love AC-30's but I sold mine a few years ago. I just wasn't using it. To loud and to heavy.
I'm not crazy about any of the Weber 12's though I've owned a bunch of them. My brother Bruce (
http://www.missionamps.com) is friends with Ted and Ted used to send us prototypes to test. I feel that some of Ted's 12's have to much cone cry and that when he puts dampening goo around the edge surround to kill the cone cry that it kills the livliness of the speaker too. Maybe that's changed with more recent production models.
I do like some of Ted's 10" speakers ALOT and feel they are the best 10's on the market: C10Q and P10RT and P10Q/30 watt especially. I just put a set of the Weber P10Q/30 watters in my '74 Super Reverb.
So what's the diff between alnico and ceramic in a speaker?
I hear the bass being a little looser and the overall tone being a little more compress-able or shape-able by my touch and my playing technique when I play through alnico speakers...but it depends on the speaker. Has to be a good one!
Ceramic seems to give tighter bass and a tighter tone in general.
My favorite of the Weber alnico 12's would be the one he used to call the P12B...similar to a Celstion G12 Alnico Blue but not quite as bright. My brother describes it as having a thumby tone! If you think about the shape of a thumb, that's what the sound reminds me of.
The other one I liked alot was called a P12Q and it was similar to a '58 Jensen P12Q...but not quite the equal of a real Jensen from '58.
My favorite of the Weber ceramic 12's is the ceramic version of the P12B...used to be called a C12B. He gave all his speakers new numbers a couple of years ago and I lost touch with the designations when he did that.
Just for the record, my favorite alnico 12's of all time would be original alnico blue or silver made in the UK Celestion G12 alnicos like those used in the early to mid 60's in Vox AC-30's. I use original Celestion G12's in my two '58 and '59 Fender tweed Deluxes. I'll take those over original Jensen P12N's anyday!
And my favorite ceramic 12's of all time would be the Celestion G12H-30, followed by the Vintage 30 and then the G12M-25. I use the G12H-30 in my two blackface Deluxe Reverbs and think they are the best speakers available for those amps.
I'm kind of prejudiced towards '51 through '66 Jensens and UK made Celestions. Been using them most of my life.
