Speaker - Jensen® Vintage Ceramic, 12", C12R, 25W, 8Ω
Typically used in the lower powered 12” amps for studio or practice, the C12R is a clear sounding, sparkling speaker, very sensitive to the character of amplifier. When paired with a stout, rich and warm electronic design it can do wonders. Ampeg® Jets and Reverberockets are just some of the most revered amps that carried C12R as their factory choice.
Guitarist Description: Warm low and mid response with smooth/bright highs. When presented with overdrive distortion, it presents smooth crunch with low-end focus.
- Lows: Tight
- Mids: Firm
- Highs: Bright
- Overdrive: Crunchy

Product Reviews
Very happy with these speakers. Sounds fantastic in my 412 guitar cabinet build. I’m glad I made the right choice.
I also have a 5E3 clone from Mojotone. I first had a wrong speaker in there made for a deluxe reverb. It was ok but the low end was super flubby and lifeless. Once I added this speaker, the amp came to life and now has a sweet tone. This was made for single coils. Humbuckers still sound a little on the muddy side. A bridge pickup HB sounds okay but this is made for singles. Great speaker.
I used this in a 5E3 clone, and wow! What a great Tweed sound this speaker yields! With sparkling highs, authoritative mids, and tight lows, it makes my Strat spank and quack, and turns my ES-150 into a throaty monster archtop.
