@newtoncr,
You seem pretty tight with ASC, how about posing the question to them?
I would hesitate to start messing w/cables and tweaks for this stuff until you've maximized the placement & setup and convinced yourself this gear is definitely a keeper.
FWIW, I've only heard a couple of horn setups that do any of what you're after, although they certainly have plenty of immediacy and other strengths....tradeoffs...always tradeoffs. Since the designer setup the rig, did he comment that HE thought is was sounding like it should? If yes, oh no!
Hate to ask but is seeking a refund or selling them on the table? Sorry to poke my head down the darkened hallway! Cheers,
Spencer
