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.

    I have a Pro Junior. I love my Pro Junior, but my drummer suggested it needed a little help sounding "bigger", so I built an extension cab and loaded it with the 12F150B. I am loving it! All of the good stuff built into the Pro Junior lives on, but some of the annoying "rough edges" have been smoothed out and warmed up. Really amazing what this speaker upgrade has done for my sound.

    This speaker somehow bridges the gap between late 50’s American tweed and early 60’s British type tones. I have the 50 watt version with the screen type dust cover in a Fender tweed deluxe. This is the only speaker I’ve heard that cuts through in a band, holds together beautifully when pushed while allowing your Fender to sound like a Fender with a British accent. An amazing and unique speaker. The team at Weber went above and beyond to get this speaker right for me. Amazing customer service. Thanks again, KT

    Bought this speaker on CJ’s recommendation to go with a 6G3 build I acquired, and yeah this speaker really amazes me. At lower volumes, I get a lovely chime and sparkle through both the normal and bright channels.

    The beauty of this speaker comes through when I have the volume cranked, which is what this kind of circuit was designed for. At higher volumes, even though the tubes start to compress the overdrive, you get a great punchy tone and of course that midrange bark and crunch you hear that reminds us of Nugent, Gibbons etc.

    Amazing work, and thank you to the Weber team!
