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.

    Purchased one for a 1×12 cabinet I was going run with my Fender vibro champ. Weber gave me advice for this with light dope and there advice was…great! Makes my 6 watt Vibro sound full n big with lots of range and very dynamic. Sounds good n crisp on clean and produces distortion with equal effort and range.

    Weber has got it going on with products and customer service. Won’t buy from anyone else.

    This speaker sounds incredible in my 1×12 British amp combo. Wanted a vintage style American speaker to get more of a fender sound. Holy crap, it’s just like having a vintage Jensen…the tone is phenomenal.

    I own a 1966 Danelectro manufactured Airline 62-9013A amp. This is a Class A, 12AX7/6V6-powered ~12 watt amp sold by Montgomery Ward in the sixties; it’s essentially the same amp as the Sears Silvertone 1482. The amp is in great condition and included its original tubes and Fisher speaker when I bought it. These amps perform best when they’re cranked, and worried that I might damage the original speaker, I turned to Weber. CJ Sutton recommended a couple of options, and after reading the descriptions and listening to the audio clips, I settled on the 12A125S; it arrived a few days ago.

    All I can say is “WOW”. The old Fisher speaker was very dark – the mid and high tones were there, but they lacked definition and vibrancy. The Weber 12 A125S has breathed new life into this old amp. I’m absolutely floored by just how rich and nuanced its tone is: it’s brighter than the original, but with no loss of depth and soul. This speaker will enable me to save the amp’s OE Fisher speaker, vastly outperform it while doing so. I used to use this amp every week or so for a few minutes; now I find myself turning to it every single day for extended periods. Bravo!!

    I built a 6G2 Brownface Princeton, but I wanted to go with a 12″ speaker and I love the sweetness of an AlNiCo speaker. I experimented with many different speakers (size, magnets, brands etc.). I finally settled on this speaker and it was a perfect choice! ( I got it B Stock) It has just the right amount of treble, without being over bearing. It has a smoothed treble response, which is needed with a Princeton circuit. The lows are full and firm. It sounds like a 12″ speaker should. It has just the right amount of mids to get a nice breakup the sets in smoothly.

    I couldn’t ask for a better speaker to go in this amp. It’s perfect for this application.
