Drum beats do not hit 200-300 watts or a watt number. Most all "good" amps have significant reserves to reach loud peaks. The only advantage to high watt amps is volume capability. It takes 10 times the power to get a perceived doubling of the volume to the human ear. Thus a 100 watt amplifier will make a speaker that can handle 100 watts twice as loud as a 10 watt amp. On the other hand if you run a 100 watt amp on an 83db sensitive speaker and I run a 10 watt amp on a 95db senstive speaker (all else being equal) then my system will play louder than yours and have more headroom than yours.
Well, our friend RGA got this one wrong, that is for sure. Smoke was right. Depending on how loud you are listening to the music, and bass drum whack can make a short term demand of 200-300 watts. That means his 100 watt amp even with a 95db sensitive speaker will compress when pushed to that volume.

Once you get below 80hz, these signals put huge demands on a amp. That is why powered subwoofers now come with mostly 500 watts and above plate amps to drive them.

I was watching the Fifth Element last night, and watched the needles on my amps hit 250 watts on several occasions. Most of the power usage was most certainly in the bass and deep bass.

All of my systems are what most folks would consider overpowered. Why do it do this? It is because a amp with plenty of headroom presents a more relaxed presentation, and when called to deliver a short power burst, it can do it without compression or overloading.

I am with Smoke on this one.
