    Perfect replacement for my amp!!!

      Comments about Jensen C12K 100W 12" Replacement Speaker:

      These speakers are the perfect replacement for my 70's Randall Commander II. The amp is basically a solid state version of a twin reverb. It has a ton of power and does clean sound really well. I blew the original speakers by playing at very high volumes. With the Jensen C12K's this amp took on a new life. The clean sounds are perfect, and in combination with my ds-1 it sounds like a vintage rock beast. Buy these speakers!

            Speaker can handle massive distortion with great note seperation and clarity. Excellent speaker in high gain amps. It is a late break up speaker as opposed to early break up speakers. Late break up speakers are true to the distortion running into them and do not add or color the distortion.

                  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.

                    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!!!!!

                        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...

                        This wonderful sounding speaker brought my piece of junk laney amp to life. Thank you Jesen for the best tone always, for any amp and style. buy it over a celestion.. which is originally what came in my laney, it sounded dull & muffled.

                        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.
