I bought the midnight 10" for my current BF Princeton build (from scratch, not a kit) but I wanted to hear the speaker. I have a generic 2 x 10 cab, so I disconnected one of the 10's and installed Jupiter's Midnight. I built an all octal Fender Super 5F4 (if memory serves) head and so far, it sounds best with my 4 x 12 cab loaded w/greenbacks, largely for there high end. Tried this head with the now 1 x 10 cab and it's magical. The best this amp ever has ever sounded. I tried a bunch of speakers, including a Celestion Creamback 90w alnico. I love that speaker for lots of things, but the match of this circuit and that speaker...chef's kiss. Modern Vintage meets Modern Vintage. Can't wait to try it with the Princeton Reverb build. Thank you, Jupiter!

Great speaker, sounds wonderful in my vintage 1964 Princeton Reverb !! Thank you!

Amazing replacement speaker for my print and style amp.

I bought three 10” 4-ohm speakers during a sale to try in the Vibro Champ, an amp I record and rehearse with regularly. The M-10C was the winner for retaining volume, clean headroom and best breakup. The other two speakers were Alnico magnets. They all sounded great but the 15W Alnico seemed inefficient. It was noticeably not as loud The 25W paper Alnico was a little too creamy when it was overdriven. It would probably sound better with an EL84 type amp. The Ceramic M-10C is staying in the Vibro Champ as the best if the Fender style shootout - but you do have to lose the tube cage as the magnet on the M-10C is ginormous in comparison to the stick Celestion. That’s probably why it sounds so good!

This speaker brought new life to my Princeton Reverb - it’s balanced and sweet. A huge upgrade over the stock Jensen!
