I don't see much about the 2430H (3" neo al comp driver w 1.5" throat) or the evo lf-8 (14" neo differential drive woofers). They both seem to be rather higher-end JBL drivers, has anyone worked with them? I understand the EVOI 324 was unreliable (overheating amps and cheap caps), but they seem to have used top-line drive units and some clever driver-level heat management. The tweeters were heatsinked to the aluminum horns (which seem to have had cooling vents that look like synergy horn midrange entrances) and the woofers are structurally integrated to the baffle segments (again, presumably heatsinking).
There's an interesting listing for just the guts- drivers, horns, baffle segments, though the asking price seems a steep for questionable condition.
