Been searching for the best speaker for a BF Deluxe Reverb for years. Tried lots of speakers and this is the best. Has more high end and low end than the original gold standard Oxford 12K5 but has the same vibe to it. Very crisp and clear. Very pleased.

Something about Jupiter speakers, they are bright and clear without being harsh/piercing. I have the 10sc, m10c-p and now the 12sc and they all have that in common.

The 12sc offers brilliant shimmers without being harsh, I use it with a BJ tweed and the 65 Princeton reissue, very good for both those amps and it's not even broken in properly.

I’ve never heard speakers like these. They make my ‘71 Bassman & Granger Plexi sound like they took acid (a simultaneously absurd and very real observation).

The speakers have a bold, slithery tone to them - more scooped than a Fat Jimmy, but they don’t lack warmth. Super smooth, no ice pick screeches, hold together well when pushed. They make me want to rake double stop bends over a P-Funk vamp for 6 hours at a time.

My guess is these probably aren’t the best for true Tweed-aholics or tight bros running a 40-pedal board, but if you like your Blackface / Silverface tones ear-bleeding loud and ringing clean bends out for 30 seconds at a time, these are your jam.

I've had this speaker in a great 5E3 Fender deluxe for years. Sounds amazing in that amp, really compliments the sound in a vintage way. Got another for a Mojotone Blackout 5E3 recently and same thing, sounds amazing. The Mojotone amp is a more refined 5E3, but still like a 5E3. The speaker really keeps and compliments the vintage character. Great speaker.

This speaker is in a lightweight American style Mojo extension cabinet. The head is a custom half power 15W Milkman Dairy Air. The only effect is a SurfyBear Classic v3.0 reverb pedal. Overall, the combination is excellent in an instrumental surf guitar band. The speaker is sensitive to the amount of treble dialed in; on 6 there is some breakup, but on 5 it’s clean and surfy. I use the 50W Jupiter ceramic for higher power gigs and this 25W for lower power ones. The 25W has the tonal spirit of the 50W, with a bit more breakup potential.
