Yeah, I'd like to look into the 4ohm rating thing! Still, experience suggests to me, that even with the BIG "MUSCLE RECEIVERS"(if there's such a thing), like the Denon 5800's and the likes, I've found from first hand experience that the power from them can't compete with even modest(often lesser wattage) dedicated power amps! But even if the power in these receivers was competetive with separate power amps, I still find that running power through a passive speaker usually has it's limitations, and the designs dictate cutting em off as "small" or at least "smaller"! Powered active subs have far more control over the bass drivers, and proper bass management offers TREMENDOUS dynamic advantages(unless using powered speakers that crossover internally to ACTIVE DRIVERS!).
So, for me, with most passive speakers, I'm going to always recommend people enlist the help of bass managment and powered woofers, etc...even if they're using dedicated separates.
Good luck
