More Weber Speakers: 12A125A and Ceramic Silver Bell

 Weber 12A125A

I bought a Weber 12A125A speaker in my chase for the ideal 5E3 tone. I originally bought a Speed Shop A12Q for Tweed tones, but it turned out to be based on an early 60s speaker. Many forum posts for the A12Q remark that it is basically a Weber 12A125S, a speaker that is an Oxford replacement. A12Q did get convincing Neil Young tones, and is likely why the speaker is popular with 5E3 players. Neil Young uses a C12N speaker with his Tweed Deluxe, so the A12Q would be closer to being period correct for that sound. The top end was a little too smooth for me.

The 12A125A is the speaker I should’ve bought in the first place. It reminds me of a thicker version of the P12Q that is in the Redwirez impulse response library, which was my reference. The bright top end works well with the dark 5E3 tone.

I can see why 5E3 user may prefer the in-room tone of the A12Q, but the 12A125A’s recorded tone is exactly what I was looking for. My experience with micing the speaker so far is that I have to back the microphone off an inch more than I would with a Celestion-style speaker. When using ribbon microphones, I have to back off to about 6” off the grille to get the low end where I want it. The sweet spot for me is typically somewhere within the dust cap. 

Weber Ceramic Silver Bell 30W

The Silver Bell was a B-Stock purchase from Weber based on my positive experience with the Ceramic Blue Dog. The Silver Bell is a take on the Celestion silver Alnico speakers used in early Marshalls. The speaker does remind me of a brighter Greenback when recorded, but the sweet spot is wider on the Silver Bell. With the Greenback, my preferred tones are around the dust cap-come junction, while I like the middle of the cone with the Silver Bell. When I was initially hunting for sweet spots, I was expecting yo find it closer to the center. I didn’t immediately gel with the speaker. However, spending more time to find balanced mic positions was a rewarding exercise. The Silver Bell works with every type of low gain front end that I’ve tried: Tweed, Voxy, Plexi.

Edit - 12/4/24 - I've posted the full extent of the impulse response capture of the 12A125A and the Silver Bell.

I find that almost all the mic positions could be useful with the Silver Bell. The IRs towards the cone, up to about 4.5" off the cap are probably at the limit of what I like in terms of high end rolloff.
