Product Details
Speaker, Jensen® Vintage Ceramic, 12", C12R, 25W, 8Ω
- P-A-C12R-8
- Sold individually
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
