Ceramic California 12

Impedance * 




Dome *

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!

    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.

    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.

    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.

    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.:>)

    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!

    I’ve been through a few different speakers for my Twin Reverb.
    First, I tried a pair of neo-magnets speakers for reducing weght; kept looking for a different tone and went back to ceramics.

    My 1972 Twin Reverb did not have the original Utah, or Oxford speakers when I purchased it, so I wasn’t entirely sure what to look for, sound-wise. I did some research, and after listening to a few clips online, I found I preferred the clearer sound of JBL speakers, after listening to an A-B test. I emailed Weber and asked about the California model, and after explaining what I was looking for, C.J. recommended the California model with the aluminum dome option.

    I primarily play old-school country music, so I like a clear, bright tone when I play, but I also want a full sound with some warmth. These California speakers delivered exactly what I was looking to get out of my Twin Reverb! The first thing I instantly noticed upon playing through them is that they don’t add any external coloring to my tone. They have a strong, but firm low end, sound full, and the highs come through very clearly, but there is still plenty of usable space on my treble control, and I don’t get any ice-pick highs (even with the aluminum dome.).

    In regards to the aluminum dome and overdrive pedals, I am very pleased with the speaker in this case, too! The California speaker does not breakup at all – it simply sends out what gets put in – but in my experience so far, the aluminum dome just seems to add a bit more presence to the overall sound, and my overdrive pedals just sound clearer to me rather than sounding harsh.

    As a reference, I also have a pair of (50-watt) Weber 12F150 speakers in my 1967 Fender Pro Reverb, and I think that the aluminum dome California speakers sound a little warmer than the 12F150 (just my experience, anyway). The 12F150 and the California models are somewhat comparable, but the California simply is a more neutral sounding speaker.

    Overall, I am very pleased with the results of trying these Weber California speakers, and these are probably the nicest speakers I have used in this amp since I purchased it.

    i read a old thread from 2008, in a forum, ted weber in person recomended the california for a old modelling amp, i purchase a one. and improves the amp models, twin reverb ,bassman.ac15,ac30, but sounds great too, with plexi, jcm800, jcm2000, special overdrive, great for modelling amps.

    Love the California. Sounds great and the aluminum dome looks killer. Unfortunately one came broken but they got on it and sent me a replacement for free. Great customer service?

    I needed to replace the two 12″ speakers from a custom pine cab used with the Roland Jazz Chorus head JC-120H from 1984.
    I had found two NOS original Roland speakers but wasn’t super happy with the tone. A mixed bag.
    So I explored options out there and settled on Weber and their California Ceramic 12 with Aluminum dome (gotta keep that cool look you know). Beyond looks, the aluminum dome, I thought, would still keep a bit of shine known from the Jazz Chorus amps.
    I have to admit that, now, this setup sounds very clear, very well defined notes coming out of the cab (HBs on a 335).
    Since that setup is a tad dark, the speakers actually complement the guitar and head very well.
    I am even noticing eq from the amp having a bit more impact on the sound.
    I have done a mod on those opamp based JCs that reduces the hum. That mod took a bit of eq effectivness away but I feel like I have more control over the tone there.
    And it’s a bi louder too…
    Shipping and packing was eventless. Will do again!
    Great experience overall, thank you!
