Ceramic California 12

  • Weight: 10.6 lbs, Diameter: 12.19", Depth: 5.25", Cutout size: 10.75"

* Required Fields

Favorite for Twin Reverb, or any amp required an extremely clean tone. In general, overdrive (from a pedal or from the amp) will sound somewhat nasally or harsh especially with the aluminum dome. Some players report good results using the California with paper dome and some distortion or overdrive. You will likely hear more higher-frequency distortion noise (especially with the aluminum dome) since this particular speaker does not aid in smoothing out the breakup, like most speakers do. In short, it gives you exactly what you give it. If you are considering the California, and want clean AND overdrive tones, you may want to check out the Ceramic Chicago.

For Twins JBL D120F tone with ceramic punch. 12", 60oz ceramic magnet, 80 watt, 2" voice coil, curved cone. Loud, smooth, uncolored, available with paper, aluminum, or the large H screen dome for more warmth.

Aluminum: Very bright, almost piercing highs akin to vintage JBLs. Good for crystal cleans, but avoid for even slight distortion.

Paper: High end is tonally between the other dome types, more piercing only under heavy pick attack. Good for brighter cleans and slight overdrive.

Large H (screen cloth): Allows the high end to be present but not overbearing. Good for warmer yet articulate cleans, but also moderate overdrive.

Custom colors available. If you choose the custom color option, please note what you want in the comments. Follow us on social media to see what we can do!

Ted Weber Speakers are built with tighter, more concentric voice coil gaps, and lower carbon, machined steel parts in the magnet circuits which yield a stronger, more controlled tone at all volumes, particularly in the low end at high volumes.

 Ted Weber Speakers are hand-built to order, to ensure the best attention to detail is paid to your speaker.  We build them one at a time, on a table - not hundreds at a time on an assembly line.  This allows us to reduce the margin for error and produce an overall higher-quality speaker.  Please allow 7-10 business days for your order to be built and then shipped.

Customer Reviews of Ceramic California 12

Big Blackface Signature Sound


May 04,2017
Big Blackface Signature Sound

On recommendation from the folks at Weber, I ordered a California 12" Ceramic with light doping and an aluminum dome for my homemade Leslie rotating speaker cab. The cabinet was a bit dark and needed a throaty speaker to make it cut. This speaker does the job better than the ones I have tried before. Sounds wonderful!

Before I installed it into my Leslie, I temporarily swapped out an EV12L from and amp I designed and built. Best way to describe this amp is close to a Mesa Mk I or a BF Pro Reverb, with added gain stage, Bassman transformers in a Princeton cab. Coupled with a Stratocaster and a TS pedal, it was extremely easy to dial in an extremely close SRV "Texas Flood tone. Big, tight bottom with a bit of upper mid cut and cry, plus sweet high-highs.

I could also see this in those low-watt tube amps, if you were looking to hang in a band situation and were looking for a louder American stack sound (perhaps with a paper dome).

This is definitely a speaker for that big mid-sixties blackface tone.

I've compared many other speakers and there are some good ones out there. Over the years I've often chose Weber's and have never been disappointed. I believe they have precise tones at a fair price. You can buy and sell bargain speakers and hope you get the right one, or you can tell them what you want and get it right the first time!

Very pure and full tone. I have it loaded in my '65 reissue Deluxe Reverb (2015). I've run several speakers in this amp and this one is the best for cleans. Very big sound. It sounds about as efficient/loud as the Jensen C12K (which is also a good speaker), but somehow the sound is purer and cleans are more bell-like. It reminds me somewhat of my old Roland JC-120, only warmer and full of tube goodness. I have the H-dome and it is very easy to adjust amp and my tele tone settings to avoid spikey highs. It also takes my OD (BBE +) and Distortion (Rat) pedals well, although my fave (regardless of speaker) is to just run tele straight into the amp. It seems to add warm clarity and sustain to the tone of my guitar. I had them do their partial break-in treatment before shipping and between that and my putting quite a few hours on it, the speaker seems like it's "broken in" and warmer now. I highly recommend for blackface circuit amps.:>)

Mr. Clean tone!

Mr. Clean tone!

I designed and built a variant of the Twin Reverb and needed speakers to handle the nice loud clean tone. These worked out great. Nice balanced tone with a hint of sparkle.

Works for me in Deluxe Reverb

About 10 years ago, I wanted to add some headroom to my Deluxe Reverb Reissue. I already had it stocked with NOS Marconi 6V6s, and preamp tubes from Muller and Tung Sol. I have the 80 watt ceramic with the paper cone, and, as stated, it gives me exactly what I give it with pure clean Fender tone. I use 4 different drive pedals and they are tuned to give everything from tweed to JCM 800 to Dumble drive sounds. I have played many many amps, and while I have tried many that sound good, even great (e.g. Tone King Imperial) nothing has prompted me to leave this set up. I like my amp to have a consistent beautiful clean tone that I can switch other sounds into with pedals. I like the sound of 6V6s better (sweeter) than 6L6s and the Deluxe Reverb is way lighter than the Dual Showman and Twin Reverb I used to own. So, after 10 years, I am still happy with my California Ceramic.

Heart warming sound

I have 4 Weber California 12" Ceramic speakers
- Custom built Super Reverb head with Dumble - 2 X12 Weber California
- Hot Rod Deluxe 1 - 1X12 Weber California
- Hot Rod Deluxe 2 - 1X12 Weber California

The hot rod deluxe sounds great after this replacement but the 2X12 on my Super Reverb sound just too delightful. Cant stop playing.
