Ok, ok, I'm not expecting any miracles. I'm fine with there being a hole there. My main concern was if the receiver auto-picks a crossover above 80 and I cross them at 80 anyway, then Audyssey filters won't be applied to anything below the auto-chosen crossover, but if the speakers cannot reproduce within that range anyway then I suppose it doesn't matter.
In any event, I will likely use RC10s if I decide to have heights.
Also, I defer to batpig's judgement on Energy honoring the warranty. He know what he's talking about.
So, batpig, what do you think? As you know, I've now made the full journey from dumpster speakers all the way to three RC-70s as my front soundstage...
Gosh, I love those 70s so much!!!
