The C12K-2 is a step forward from the C12K. It has a different cone membrane which grants a more extended treble response to increase the detail and the shimmer of the tone, yet retains a well contoured smoothness. Equally at home with clean and mid-gain crunch tones, the C12K-2 offers an outstanding response to the player’s touch. When used with higher gain tones, it offers a powerful, rounded, organic tone that delivers a full-bodied thickness to single note lead runs.

  • Lows: Tight
  • Mids: Warm
  • Highs: Smooth
  • Overdrive: Creamy

Guitarist Description: A real workhorse, heavy on the mids with a solid, straightforward tone. Presented with overdrive distortion, it powers through with lows that are bold and heavy.

Bassist Description: Not recommended for bass.

I installed two of these C12K-2 speakers into an Orange PPC212 closed back cabinet, to use with my Orange Dual Dark 50 amplifier. They are a perfect match for both heavy metal and hard rock guitar riffs, but can turn around quickly and be equally adept at clean, intricate tones that work well with jazz and country styles as well. Tone descriptions aren't always accurate, but the ones Jensen provides for these speakers are very accurate. These speakers provide tight (not flubby at all) bass, mids that are present, but not overbearing, highs that are very smooth and not piercing, and overdrive tones that are not fizzy or harsh, but smooth and, as stated, creamy. In my opinion this is like the missing link between a Celestion Vintage 30 and Celestion G12H Anniversary. No ice pick / ear fatigue issues like with a Vintage 30, but plenty of lows and low mids, like with a G12H. The price for these speakers is very reasonable, too. I highly recommend them for closed-back 2x12 cabinets with British-style amplifiers. I would imagine they would also provide a very nice tonal alternative in Fender-style amps as well, toning down the piercing highs that sometimes result from those circuits. The Jensen C12K-2 is a contender in the field of British-style speakers, providing a very versatile tonal combination unique from other companies' speaker offerings.
