Re: Speakers for '72 Fender Twin Reverb
Take it from me to say the least, go with "better than vintage" over "vintage" specs. Who cares what they used in the 50s, 60s, 70s, whatever. Things were MUCH different then, go on what sounds best NOW. I would definitely go with the half alnico/half ceramic job. Even though I never tried them both in the same amp, I really like alnicos. So in the same amp with a ceramic in a twin reverb, the amp will have that extra complex mids and chimey character that alnicos have with the good low end and punch of ceramics - sot of a best of both worlds type job.
People put Celestions G12H30 70th Anniversaries in Deluxe Reverbs and they sound much better than Deluxe Reverbs with historically accurate Weber Jensen Clones IMO. Dead to vintage specs isnt always the best. Go on what sounds best to you. I never had experience with the Weber California 12s, but I tried the Twin Reverb Custom 15 with the eminence/fender JBL clone speaker with aluminum cap and it was very very bright as was mentioned. Definitely take historical accuracy with a grain of salt, buy based on if your amp needs more mids, highs, lows, whatever.
What do I want? Ok, if I was to go about it that way, I want a loud, crystal-clear set of speakers. In practice, I rarely mess with the knobs on my amp, so I'd want something very accurate and touchy without being too easily driven into feedback. I want speakers that at max volume (entire amp: since mine is one of those TR's with the channel volume and separate master volume) will distort just ever so slightly (think Boss BD-2 Blues Driver), yet amp at max concert volume (not max volume, say around 7 master 5 channel) will be loud and crystal-clear without any breakup.
That's what I really want. Some of Weber's speakers are "ceramic-boosted" alnico speakers. However, in terms of my price range, I want best bang for the buck. I'm not a "pro touring musician" yet, so I have a budget. I'm thinking I might even have to go and email a lot more people who have actually put replacement speakers in Twin Reverbs. The sound I want, however, is that of the '65 TR reissue, if I have to compare it to something. Twin Reverbs sound like what they're going to sound like, and I don't want my amp to sound like something it's not. If I want a Marshall, I'll buy one. If I want a Peavey, I'll buy one, etc.
Am I making sense? Anyways, so other than buying the stocker Jensens that the '65 TR comes with, I'd like some Webers of that variety. I'll go find more amp repairmen online and ask them for their advice, unless you guys have more advice to offer. BTW, no "made in China" speakers, please.
EDIT: By the way, Ted Weber already answered this question perfectly, I think, after I re-read what I originally emailed to him, so I'm going to go with what he said unless I find better.
