High Powered Speakers?

"Don't playback the telarc digital cannons at full tilt into a set of mini-monitors with a 1000watt Krell."

Ohhh, can't we do that just once? Just to see the fire and smoke? Pleeze? Slappy will let us use his ghetto system...

You can lay the speakers down on their backs and take bets on how high the woofer can launch a tennis ball.
It'll work at least once.

With MG 1.6 speakers there is no doubt that a 350 watt Adcom amp sounds much better than a 100 watt Adcom amp with similar specs (except for power), even though the power drawn (even peaks) is well within the 100 watt amp range. I think that there are other amplifier characteristics that come along with high power, and these, rather than the high power capability, make the difference.

JBL loudspeakers are probably the best choice for you. Or you can refer to some great speaker models for wedding here.
