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.

    Could not be happier with this speaker if I tried ! Bought it to use in a 1×12 cab to connect to a Fender 68 Custom Vibrochamp Reverb. Was looking for a bigger sound and more volume with the cleans and that is exactly what it delivers ! Takes dirt very well and doesn’t have issues with any of the effects I have tried out. TYVM !!!!
