I recently bought an 8SC for my old silverface champ. What a difference. The original speaker was missing when I got the amp. It had a perfectly decent sounding Eminence in it. But the 8SC made the amp louder, cleaner, and just plain bigger sounding. The speaker could easily be mistaken for a 10. I can't remember another time a new speaker made such a dramatic difference. I would recommend this speaker to anybody who wants to get more out of an old champ. Mine is now loud enough to keep up with a light touch drummer for small venue gigs. I'm super pleased!

I can’t be happier with this speaker. It sounded amazing right out of the box. More companies should offer speaker break-in. It makes a world of difference. This is my third speaker from them. I put a midnight ceramic 12 inch and a midnight AlNiCo 12 inch in my vintage 1966 Pro Reverb and it instantly changed the sound for the best. Jupiter‘s are the best American voiced speakers in my opinion!

The Jupiter 8SC sounds absolutely stellar. It arrived pre-broken-in and sounded great from the first note. I’m very happy with it.

Heard this in a YouTube comparison with a Alejandro GA sc64 12" by Eminence and it had a little something extra.Truly an amazing speaker.The Eminence is excellent but the Jupiter lc12 is magical.Will be buying another for my 65 Princeton Reverb Limited Edition amp.Great job Jupiter!

I already wrote a review on the speaker I received, but am adding here that to my ears there is a noticeable smoothness around the edges when compared to speakers of comparable design when new. I imagine it will smooth out even more, especially playing dimed, as I always do for a least a little while whenever I use the amp this Alnico 8" is in. It can take a while to settle a speaker as much as this one felt straight out of the box. I believe the service is well worth price.
