Alnico Amsterdam 12

Weight: 11.75 lbs, Diameter: 12.19″, Depth: 7″, Cutout size: 10.75″


Impedance * 




High power 12″ AlNiCo speaker for amps where reducing treble response is desired. Big full tone, strong low end, emphasized mids, smooth and rolled-off treble. Great with clean all the way to high gain. Hemp’s longer fibers give treble notes a sub-harmonic richness that warms the sound. Compressed and fattened at high volumes.

12″, 40oz AlNiCo magnet boosted with ceramic, 60 watt, 2″ voice coil, hemp cone.

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.

    these speakers bought sound out of my twin (when paired with an alnico california) that I never heard before. my twin reverb is a 1973 that has been blackfaced. I run a matchedquad of 1966 rca 6l6gc’s. I also use a weber power attenuator when I want the cranked tone at a moderate level. it took a while to get the speakers but was well worth the wait
