Nothing was wrong with the OEM 12-65 ROLA but I have always wanted to try this 12LA Jupiter .. I was very impressed with the build quality .. I had this bunt in .. sounds fantastic very articulate upper mods and tight bottom .. highly recommend Jupiter .. very responsive customer service as well ! 5 stars !

Decided to upgrade from original 8” speaker in my old Gregory “widow maker” type amp (made safe with isolation transformer). While it only outputs about 2 watts., there aren’t a lot of options for 4 ohm 10” guitar speakers. I really like the Jupiter caps I’ve purchased, heard good things about the speakers so took a chance. And guess what? My little amp sounds glorious - bigger, louder and with way better note definition when amp is cranked all the way for saturated overdrive at bedroom levels.
PS The Jupiter break up in service was also a big plus - no way 2 watts were ever going to break that speaker in.
PPS Have to admit that green finish is mighty handsome.

The Jupiter speaker sounds great in my 70s silverface Fender VibroChamp, much better than stock! More headroom, the low end is tight, and tons of tubey character. I don’t know how much the break-in service adds, but for $12, why not?

Fabulous speakers!

Great speaker, great shipping, great packaging, excellent break in service. Could not have asked for more.
