Keith E.
Great sound right out of the box.

This speaker is truly amazing. It has more bottom end than I expected out of a 10" speaker, it is clear on the top end without sounding harsh and seems to be able to take a beating without bottoming out. Somehow it is clear and bright, tight in the lows, with a midrange that is up front but not overbearing. It just sounds right.


Sounds great!!! Smooths out just the right amount of sizzle with a vintage Princeton.

Featured in ToneQuest Report.

The M10C has a slightly smoother sound that retains headroom. Similar to the 10LC but with less output but a more balanced sound with more presence and sparkle on the top end.   Initially intended for studio or home use, musicians claim it to be the closest to the original C10N from 4 and 5 decades ago.  The standard voice coil gives a more 3D presence when compared to a paper voice coil.

"Through the Princeton Reverb, thanks to the 50-watts, it gave the amp a sweet and crystalline shimmer, and a bit more headroom, which is a good thing. The Jupiter 10 seems to somehow meld the best qualities of a ceramic and alnico into one sublime, strong and smooth pureness of fidelity that is inspiring. The top end is nice and pleasing, and not as punchy bright as our 1959 C10N. The vintage alnico Jensen P10N is lower powered, sultrier and smokier. We love this Jupiter 10. It sounds old, too. What a fascinating blend of clarity and roundness. Good lawd they got it right."
