4ohm 12 inch low wattage ceramic for an external cab running a tweed champ or a 70s reissue champ depending on my mood. Exactly what I needed for these amps. Sounds killer pushing these amps on 10 and working the volume control to get tones. So deep and warm with the Jupiter speaker. I am getting EXACTLY what I had hoped for and I could not be happier!

I purchased this speaker for a Victoria 5112 amp, a 57 tweed champ clone with a 12-inch speaker. The stock speaker worked great, but it did not deliver the champ tones I was looking for, which was the reason why I purchased the amp. Out of the box, the 12SC speaker added the vintage crunchy tone I have been looking for and at a lower volume. I mostly play at home or mic the amp when I play live. So, this speaker not only sounds great, but it looks vintage and makes the amp significantly lighter when I need to venture out. I highly recommend this speaker if you want that tweed champ tone in a bigger box.

I'm a big fan of the Jupiter SC series speakers. I also have had the 8SC in a tweed Champ (where it was a tad dark) and in a '78 Vibro-Champ (where it's perfect). I had tried a bunch of speakers in my Clark 5E3 tweed Deluxe. Large magnet ceramics were plenty loud enough but lost the tweed Deluxe signature sound we know and love. I also tried a Weber Signature alnico, but it fell apart too quickly when pushed. After weighing my options, I decided to try the Jupiter 12-SC. Shipping was fast and reasonable (glad Jupiter fixed that problem!). Right out of the box the Jupiter 12-SC sounded better than the speakers I had tried previously. When pushed it compresses and distorts nicely without falling apart. There is ample high end, but the treble register is not distracting or harsh. One thing that surprised me was that the sonic signature could be mistaken for an alnico speaker. The speaker is not fully broken in yet, but I'm noticing further improvements as I continue to play it. All in all, a good purchase!

Using it with a '65 Vibro Champ in a MusicMaster cabinet. Hasn't broken in yet, but so far, so good.
