Original G12M-25 Tone. 12″, 30oz ceramic magnet, 25 watt, 1-3/4″ voice coil. British Kurt-Mueller ribbed cone.

Similar to the original G12M-25, it is aggressive, yet has a smoother overdrive distortion characteristic. Maintains good detail and midrange complexity.

• Paper cone – standard Kurt-Mueller British cone used in most of our British type speakers.  the 75Hz cone is the more “classic Marshall guitar tone” if you will.  75Hz is the general name that has been given to this cone since the 60s, even though the resonant frequency is closer to 82Hz, which is low E on a standard tuned guitar.  Standard low end with a midrange bump, and clear articulate high end.

• Hemp cone – very soft material, darker, warmer, foggy and less focused. Hemp’s longer fibers give treble notes a sub-harmonic richness that warms the sound. great for that hazy stoner metal thing where articulation isn’t the objective. it cuts the treble, but it also affects the overall response and feel to be more squishy.

• What’s Dope?

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’ve had one of these in open back pine cab that I use with various tube amps for several years. Prior to that I was often swapping out different speaker trying to find one that sounded right—I’m very pleased with the 1225. It delivers great Greenback style tone that is complex and warm without harshness. It’s not a super efficient speaker so I can push my amps a little harder than with other speakers. Thanks Weber for great speaker!

    So blown away by these speakers. I have many speakers in many cabinets. Everything from Celestion Vintage 30 to Greenback to G12H to WHG Reapers. These Webers outclass them all. Primarily, I love Greenbacks above all other speakers, which is why I wanted to try these. The difference is subtle, but remarkable. The Webers don’t have any fizzy high end…the sound is pure old school and reminiscent of audio tests I have heard demoing vintage British Greenbacks. Totally happy with these speakers!! Highly recommended. 16 Ohm 25 watt in a 4×12.
