User Reviews

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 four Mod 12-35's to replace the cheap Chinese drivers in an old cab I had. The Chinese speakers were great for bass guitar but were awful for electric guitar. These babies ROCK! Great bass response, nice chimy highs, not too much breakup with distortion. The lower SPL lets me run my amp at a higher output for more power tube saturation without being overly loud. They sound like greenbacks only better! The best thing is, they are light! My 50 year old back loves them, as do my 50 year old ears! Did I mention the price is right, too? I am now a Mod convert! Thanks, guys (and gals)!

I've used the Mods. Love the 12 incher. Hope to be able to use more in the future.


I ended up purchasing a vintage Mod 35. I love the speaker’s sound, response, and slight tone coloration, and will be ordering 4 more shortly for my 4x12.
