i heard one of those in a record store a while ago, two of 'em mounted high on a wall, didn't notice how much space there was behind 'em. but i was struck in that they didn't have the forward bright sound i'd heard in every other Klipsch product [aside from their Heresy] i'd heard up to that point. they were decidedly mellow. i don't know what kinda amp the store was using to power them with. but i decided then that if they all sounded like that, that i'd like a pair or two.
