[QUOTE="eharri3, post: 5685427, member: 591579"] There was more to it than mismatched rms ratings for someone to blow 70 watt components with an 80 watt amp. Like maybe that person does not know wtf they're doing. Whatever the amp's rms rating is, it will only see it for a few brief seconds in the song if the gain is set properly. The rest of the time it's putting out considerably less as the song changes in pitch and volume. You can connect a 70 watt speaker to an 80 watt amp but if it's set up right that 80 wattts comes once in a blue moon, the rest of the time its much less. If OTOH you send a speaker every bit of its RMS rating and then you clip it alot it's bound to go over its thermal limits and fry in short order. This often happens when people buy into that crap and focus way too much on matching numbers. And then they wonder why they're feeding a speaker every bit of its rms rating but no more and it's still not loud enough in normal listening so they fix it with 'gain overlap', basically a crutch for people not running enough power. RMS power relationships do not blow speakers, and there is really no such thing as a speaker that only 'likes' to be connected to an amp that produces less than it's rms power rating. This is a myth perpetuated by people who don't know how to control an amp's power delivery and be nice to their equipment while getting the most out of it. It is designed as a general rule of thumb to prevent people who don't know anything from blowing up one speaker set after another because they have more power than they know what to do with.
