I tried several speakers with my vintage Fender Deluxe non-Reverb amp. Weber, Fat Jimmy, and Eminence all worked well, but the goldilocks speaker was the M12C. As good as it sounds, it also feels good under the fingers, which is just as important. It responds very well to adjustments in guitar volume and tone, which players don't think about until they experience it. It has just the right volume as well, don't let the lower sensitivity fool you into thinking it's home use only.

I have a Jupiter 12LC in my '74 Fender Musicmaster Bass amp.
Just 12 watts but the tone is fabulous. I could not be happier.

Bought a pair of the M12c speakers to replace the original speakers in a 70's SF Pro Reverb. I couldn't be happier w/ the purchase. Great full, warm, clean sound I was after, no harsh breakup I was experiencing w/ the stock Fender's . The Amp was recently serviced and between that and the speakers completely turned the amp around. Classic Fender Jensen sound !

Great sounding speaker! I installed it in my VHT Special 6 Ultra and started dialing in my tone. I have to say that I am very happy with the result!

Replaced the stock 12", "Hemp" Speaker in a new Fender Princeton Reverb. Great, full tonal range in comparison. I am very happy with my purchase and absolutely recommended.
