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

Many of the older Deluxe's had Oxford's and not Jensen's. Either speaker will work and the C12Q is 10 watts louder at 35 watts.

Typically you want to have a speaker that is higher in wattage than your amp. With that in mind, I would recommend the C12N.
