re: the Athenas - Yes, even their manual says they need about 40 hours to
get them settled in (see sticky above on discussion of if there is such a thing as Speaker Burn-in)
re:BICs I just bought a pair of the DV62LCLRss to use in my 2.1, and am quite happy w/ them so far. Lots of ppl rush right out to Ed Frias' mods to "fix it", but I say let them play for a week or two first , then decide.
re:Onix ELTs, they have been discontinued, but are being replaced by the new REF .05s, coming in December, with bigger cabs (gorgeous rosewood)updated crossovers, & slightly different woofer. I have an order in on a pair, can't wait to hear them.
I owned Athena B2 + ASC-1 center & liked them, but found they got trounced
by the Infinity Primus 150/C-25 set up easily, with cleaner mids & highs.
YMMV
