about 20-30%
800W RMS = about 1000-1100W AES |

AES power handling is perhaps one of the best defined ratings for loudspeakers.
It is simply pink noise filtered between 125Hz and 8kHz with a peak to average ratio of 6dB and applied over a period of two hours. It is one of the better indicators of both the thermal and mechanical aspects of power handling. ^ Found this on another website, hope its helpfull. |

so if i have a bass bin at 1600w aes then an amp of about 1200w rms would be about right for it?

Therefor the recommended ratio is usually 1.5 to 2 times amp power to speaker power. Nevertheless, it would be ok to use a 1200W amp on a 1600W bin, but you would probably be far from getting the most out of your speakers. Just don't let the amp clip too much (or at all), because you could easily fry the drivers like that (yes even if the drivers are 1600 and the amp "only" 1200W). Hope it helps, cheers..

what about brickwalled dubstep? playing out of a laptop with a hacked copy of ableton? there aint any peaks there, its just one squashed, badly mixed peak. 1200w rms will over heat just about any woofer over a 2hr period in situations like this.

REFLEX ALL THE WAY.... (however, im playing with horns again...) That ok Mister Valiant? :)

As I meantioned above, a 1.5 ratio between amps/speakers is a good starting point. But you don't really have to approach it in such a detail as the marketing departments of many of the amp brands/manufacturers sometimes go pretty delusional when it comes to printing numbers on the spec sheets of their products. - eg. the RMS/AES difference will be relatively negligible in comparison. |

A clipped signal is bad, regardless of wether it's origin is at the end or beggining of the signal chain.. |
