Another item worth noting is the effects that high power have on your listening experience. Higher power to your speakers translates to more heat that must be dissipated. Speakers are not heatsinks and they are not terribly efficient at cooling themselves. The sinister aspect to this is that as the voicecoil temperature rises, its resistance increases. As its resistance increases, the power to the speaker goes down. As power to the speaker goes down, SPL decreases. So now a "portion" of your high powered amplifier is acting as a heater . The question of course is to what degree? If you are putting 300W into a speaker, is 150W going into heating? I'd need to work the math out on this one.

And now something even more sinister. Ever wonder what happens to the speaker's passive cross-over design with these heating effects? Very simply, the cross-over frequencies will shift with volume.




I wonder if Ian knew this when he designed the M80s
