I've been playing guitar for nearly 50 years and designing and building speakers systems for musicians for more then 40 years. I bought a new Trace Elliot Bass amp a few years back that had a Jensen MOD12-70. It ended up in my Fender Deluxe, exactly the sound I've been searching for for years. Now I've got another MOD12-70 and P12Q, they make all other speakers sound muddy (no not Mr. Waters). All my amps are being changed to Jensen. If it ain't broke don't fix it.

The MOD12-70 is loud, dynamic, and well defined. It has a defined warm crunch response to overdrive distortion.
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've used the Mods. Love the 12 incher. Hope to be able to use more in the future.
