"Man! It's almost like there is a really slight tremolo or vibrato, or some pedal that someone would use to subtly "pretty up" the tone a little bit, on all the time with these speakers. I just got the 212 cab completed with the Jupiters that arrived today. As soon as I plugged in, it scared me because it had that really harsh top end that I'm trying to get away from. It's kinda weird because after like 20 to 30 minutes the harshness disappeared. Maybe they just loosened up a little bit? I can't imagine how they will sound after about 40 or 50 hours. I've always had good luck with the eminence line and the webers, but these blow them out of the water. I still can't figure out why there is absolutely zero info on the web??? Maybe I should do a Harmony Central review or something. Any suggestions? I would also love to A/B these against the really high end speakers like the EJ eminence or the celestion gold (I think that's it???). I can't see how it's possible to get any better. I played a blackface princeton, a radically modded silverface champ and a rebuilt Blues junior that is actually over 20 watts and 4 different strats, a Paul, a 335 and a hot rodded Esquire and all combos completely blew me away! I'm wondering what makes these so different than everything else that's out there? Thanks a million!" Andy C.
