Very defined and musical

Comments about Jensen C12K 100W 12" Replacement Speaker:

This speaker is very impressive. Comes OEM in my 65 Deluxe Reverb. It is my first experience with Jensens (usually, I use Eminence Speakers) and this speaker covers all of the bases with ease. From jazz to country and rock, if you like a punchy, immediate soundin speaker with nice mids and good solid bass - this is your speaker.

Excellent speaker for Fender amplifiers

By Wpgjazzman

from Winnipeg Canada

Comments about Jensen C12K 100W 12" Replacement Speaker:

This is the ultimate replacement speaker for Fender amplifiers that produced the great 50s and 60s rock and roll sound. I'm referring to the Duane Eddy, Ventures, Gene Vincent and Beach Boys eras.I put these C12K speakers in a 2-12 Bandmaster cabinet and was amazed at how the sound improved over the E*in*ce speaker that were installed to replace the original 1966 speakers.

warm and punchy

Comments about Jensen C12K 100W 12" Replacement Speaker:

Replaced a blown Eminence spkr in a Fender Twin Rvb amp. Although the Eminence is slightly brighter, with an SM57 at close proximity, the C12K has a slightly warmer, yet clear tone, and does justice to the Fender amp.

I am very pleased with this sound!!!

By Willyzapa

from Medellín, Colombia

Comments about Jensen C12K 100W 12" Replacement Speaker:

I have had a lot of amps and the speakers they come with, I bougthA Fender Super Twin Reverb 1978 and replaced the speakers with this Jensen, and I couldn't belive the tone, the fullness and the clarity these speakers did to this old amp, wheter I play with my Strat, Tele, Gibson Les Paul, Gibson ES 335 Hollow body, Rickenbacker 450, or my Squier telecaster custom ultramod, glued neck to body and seymour duncans...the sound is uncomparable!!! After playing for a wile with tube amps and this very good speakers, I have to say I would never want to go back to solid state Amps, I prefer the tone, vibe and vintage sound.... That's all...

    Comments about Jensen C12K 100W 12" Replacement Speaker:

    So if you're in doubt of your current 65 DRRI speaker, I have some experience in the matter of speaker swapping.

    I tried 7 different speakers, C12N, 12F150, P12N GA-SC64, Cannabisrex, Creamback, and of course the C12K. The only reason I ever started changing speakers is because people on forums were saying "the magic is in the speaker change", so I got on the band wagon. I went through each and every one of the above speakers, and inevitably came up dissatisfied. I owned my DRRI for less than a year in this time period, and inevitably I ended up getting a C12K after I sold the original. Once I installed the speaker it was like reversing time back to the moment when I bought the amp, and i remember just melting into the sound coming out of the amp. That was the C12K pumping out that sound, so I cannot believe I spent so much time just burning money on something I ended up not needing.

    That was my experience, the C12K was Fender, for Fender. I don't have the time to mess around with speakers, and it's a shame I wasted so much time when I could've been learning, but if nothing else I got experience, and I hope that someone else may consider this. Really, I have no idea why I changed anything on the deluxe, even though I changed the tubes and got some mods, I can't say it's any better or worse than the day I got it. If I could go back in time, I would've just left it stock, there was never an issue with the amp, including the speaker.

        Comments about Jensen C12K 100W 12" Replacement Speaker:

        Came standard in my DRRI. Great mids and very nice bass and despite the forum musicians who play mostly on their computer keyboards - this speaker does not need to be changed out.

        Yes it does appear to take quite a few hours to break in but after about 20 hours I can hear it improving still rounding out the bass and smoothing highs.

        I like it so much I,ve purchased one for my Tech 21 Trademark 60 with startling results.

        I play mostly clean or on the edge of break up so won't speak to it's ability to handle distortion.

        I've been a Vintage 30 lover for years and this beats it everywhere IMO. Better bass and not quite such a prominent mid range and it can sparkle if you want that. Great note seperation
        and definition.

        Many change this speaker out and then find it was the best choice - give it a proper try out and you won't be sorry.

        Comments about Jensen C12K 100W 12" Replacement Speaker:

        I put this in a Crate 50W combo as a replacement speaker. It takes a beating without breaking up and provides good clean or distorted ear-bleeding crunch.

          I replaced the stock Eminence Legend speaker in my Fender Blues Tweed Deluxe Reissue amp with the Jensen C12K 100watt speaker. I am very impressed with the performance of this speaker and I will now be replacing both the Eminence Legends in my Deville 212 with this Jensen performer.

              I installed this in my Fender Deluxe Reverb that I purchased new in 1973. I replaced the original speaker which I intend to have re-coned. The tone is right on the money. I re-tubed the amp as well and now it is back to its original sound. I love this amp/speaker combination.

              The clean sound you get and the warmth of the tubes through the speaker is classic Fender! Great Great sound.

              I made an excellent choice!!!!!
