Warm, well balanced tone with low end focus. It responds to overdrive distortion with a rich smooth crunch and bright lead-voice fuzz.
I just want to say that the pair of 12" MODS I bought and installed in an older Kustom cabinet sound fantastic. I have used many Jensen products over the years and they have always been my first choice. The reason is simply - they are the best. In my opinion anyhow. I have never been dissapointed with any Jensen speaker I have ever had. You can hand them a hefty beating and they hold up well. They will remain my first choice.
I purchased two Mod 12-50 's, one Mod 10-35 , and one C10R . I have them in a birch, slant back cab with the two 12" diagonal to one another and the two 10" diagonal to each other . I love the dynamics of this combination of speakers when playing through a tube amp head. I think it sounds better with the EL-84 head than with the 6V6 head.
I've used the Mods. Love the 12 incher. Hope to be able to use more in the future.
Great speakers. Liked them so much I picked up a C12N, P12Q and MOD 12-50 to re-do three respective new amps to give them a more vintage tone.
