those QS8 can take much more power than your receiver puts out.
first guess is you overdrove (to clipping) the amps feeding the QS8's.
if your system is well setup with no bass/treble boost, and if you listen to music or movies at realistic levels, then you should not be overdriving the amps/speakers.
when you overdrive an amp, the output power can be much more than what the specs say, but this overdriving produces distortion in the sound, and it can blow up speakers very easily.
As soon as you hear some distortion, that indicates you're overdriving the amp; you should then lower the volume enough that there is no distortion at all.
If you hear speaker bottoming, that's even worse.
What's the size of your AV room? If it's a very large room, then maybe you don't have enough power to get realistic levels without clipping the amps.
I've never used "absolute", so i can't comment on that.
