The real issue with those speakers is that they are made to break up much earlier than we would like as loud and clean Jerry players. A mutron will make the speakers fart like a well fed trucker. If I were trying to upgrade my twin with new stuff on the cheap, I would consider the eminence Commonwealths for the twin, especially if $200+ a piece JBL speakers are tough to get. Actually, it seems like a 70/30 gamble to find good JBL's anymore, especially a pair. Yes the commonwealths are from the same speaker maker, but totally different speakers. They charge you for the quality they put into them, they're not $30 speakers. According to them, the E120 was the inspiration/tone palate for the speaker. They are made to give you clean headroom, have the hi-fi aluminum dome thang/look and are db sensitive like the JBL's.
I am not sure about the neo's and warmth, the reviews tend to say otherwise, though I have yet to try them. Altec's, EV's and other vintage higher wattage speakers can possibly yeild similar results too.
