I just purchased the M10Cpaper vc speaker in my new build princeton reverb. I repair vintage amps and have heard many princeton reverbs. This new Jupitor speaker is exactly what I had hoped for. Balanced with enough bass but not overwhealming and crystal highs not strident in any way. Out of the box it sounds perfect. Highly recommend as a C10N modern replacement speaker for a princeton reverb. Very impressed

I knew I needed a Jupiter after listening to Chicago Blues Box Amps. I upgraded my fender combo and did a fair side by side. This speaker is crystal clear. So good Im about to buy another for the other Fender combo

I am loving this speaker. I paired it with a Tone King Gremlin. Sounds great! I have rolled several speakers paired with my Gremlin including a Cajun, V30, WGS ET(nice speaker by the way),others,, and ended up with the 10LC-P 10" 25W Vintage American Ceramic as the keeper. It’s a little bright but I like it that way. I plan to try the 10LC 10" 50W Vintage American Ceramic in the future as seems it would be a little less bright and potentially “bigger” sounding but I am in no hurry to replace the 10LC-P. Truth is I will probably never swap out the 10LC-P. It sounds good so why mess with it..
The bass is nice and tight, good mids, and sweet highs. I highly recommend it for a Fender type amps. I was a little concerned that the tweed/overdrive/pushed mode might be harsh/shrill but nope it sounds good to me and is nice and compressed like I like it. Great speaker! I highly recommend it.
