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 had a 12a150a installed by Mike Marsh in a 5e3 Deluxe he built for me about 4 years ago. A really great build which no doubt sounded the better for this amazing speaker being installed! It gives the Deluxe a really full blooded, big sound. More than enough volume to gig with, even with a fairly loud drummer. With this speaker in place the sound is really vintage correct I believe. Warm, responsive with plenty of lush low end. Highly recommended!

    These speakers sound unbelievably good. I ordered a low-power Twin amp kit and they came with the kit. I tried them on several other amps just to hear them (while waiting to finish building the Twin) and they are now my favourite speakers for all of my amps.

    Compared to a Fender Eminence or JBL D120 they sound cleaner that the Fender Eminence and warmer than the JBL. I’ve used them with a Princeton Reverb and a vintage Fender Deluxe Reverb, etc. and they have better tone than the original speakers they replaced.

    They have a very full, clean and accurate sound while sounding vintage correct.

    They may well be the best sounding speakers I’ve ever used and can cover everything from jazz to blues, rock and roll, disco, you name it … and I’ve used a lot of vintage Fender amps over the last 60+ years of playing professionally and for fun.

    In my opinion they are worth every penny. They are very responsive in a good way, they sound and feel ‘just right’. They bring out the best in spring reverbs, too. My speaker prayers have finally been answered!
