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.

Customer Reviews of 12A125A

fantabulous speaker FOR THIS HARP PLAYER

fantabulous speaker FOR THIS HARP PLAYER

This an expressive speaker with ringy, chimmey character and holds the bottom end beautifully when I drill it down low. The colors of the tone are absolutely beautiful. It's a close second to my favorite speaker Weber's 30 watt 15" alnico speaker. I run the 12's in a 2x12 '59 Bassman. Oh sweet baby jesus it sounds good. I run the 15" alnico in a '63 pro with some BF circuit tricks, at 32 watts. People come up to say "hi", but hug my amps.
Oh, I forgot to say that I am a harmonica player.

My Search Is Over ...Fantastic!

My Search Is Over ...Fantastic!

My associates and I have been looking for a speaker that could compare to a vintage 1954 Jensen P12Q. There was nothing I tried that came close until we found this speaker by complete chance. I purchased a 1962 Fender Bassman Head & Cabinet and found out after the fact the speakers had been replaced. I was disappointed at first because I felt the price I paid for the cabinet was too high considering it had replacement speakers. However, we decided to compare it to a cabinet we has with original vintage very early 60's Jensen P12Q speakers. Bottom line ... we were all blown away by the quality of this speaker. Dare I say it actually have sounded better? . It even has a real seamed paper cone the way it should be done. Awesome Job Ted Weber! Keep it up and please do not change a thing! Highly recommended!

The best speaker for a 5E3 - period.

The best speaker for a 5E3 - period.

I built a Mission 5E3 clone and tried multiple speakers in it trying to find the right one. That search ended the moment I installed this speaker. It's even better than the vintage 1960 Jensen P12Q I had at the time. It's difficult to describe how it's different other than the 12A125a makes the amp sound "alive". If you're on the fence about whether to order trust me and do it. You will not regret the purchase!

I put this speaker in a 5e3 I built and can't even believe the difference it made. By far the best speaker I have ever heard. I never knew I could get so excited about speakers until I stumbled across Weber. Weber speakers are and will continue to be the only brand I use.

Excellent speaker.

Excellent speaker.

I have a 2 x 12 pine cabinet running two of these (30 watt speakers) with a Marshall JVM205H and the tones for both crunch and clean are fantastic. I would describe these speakers as very detailed and even; capable of covering a lot of ground. The clean tones are very musical, detailed and full. They also sound excellent with overdrive and distortion. Not always the case with alnico's. A quality speaker for sure. Would buy again.

12a125a Music to my ears

I put one of these in my Fender Deluxe II ( 1984 Rivera Fender )
Every time I play out somewhere, I get offers to buy the amp.

This is the sweetest sounding speaker to my ears.
I like a les paul with classic 57 humbuckers, a modded ts-9 and classic rock. Sounds great (crunchy) with p-90's as well.

Just perfect

Just perfect

I have 2 original Fender tweed deluxes: a 1954 wide panel and the other a 1957 narrow panel. I use this Weber speaker in both amps while keeping the originals safe in storage. In my opinion the 12A125A speakers bring out all of the glorious tones of those amps without the early farting out of the originals speakers. Really a remarkable speaker -I never wonder what it would sound like with another brand because I'm totally satisfied with this one. Thanks very much Weber!

Great speaker and service!

Great speaker and service!

Awesome speaker! It matches perfectly with my Tweed replica. Fast and efficient service as well. I would highly recommend Weber Speakers to anyone!

Was looking for a nice balanced speaker for my 5E3 build and I kept coming back to this guy. I built a head/cab for the 5E3 and when the volume is full throttle this speaker just growls. Absolutely amazing fit for anyone looking for that "tweed" tone.

Excellent choice for Princeton Reverb

Excellent choice for Princeton Reverb

I bought this to put in a Tweed Deluxe build which is an obvious choice. Just out of curiosity I tried it in my hand wired Princeton Reverb and was very pleasantly surprised. It tamed the high end and really gave it a rich warm bell like tone at low volumes then fattened up at higher volumes taking breakup/pedals well as this type of speaker is known to do. It has turned out to be the perfect choice and fits the bill for home or band situations. Highly recommend it as a great speaker but particularly for the Princeton Reverb. I play Classic Rock, Lou Reed/90's Space Rock, Jazz and Blues.
