lol... yes, it is ALWAYS better to be safe than sorry... 
but just in case it does decide to send flames up through the vent holes, make sure you videotape it and put it on youtube for the rest of us to see...
however, i feel safe in saying it won't... the avr will handle it... the thx certification (even though it's "bought") tells "us" a few things, one of which is that it will safely drive "reasonably low" impedance loads... even ignoring that, there's boatloads of anecdotal evidence that says you'll be ok...
well... "more powerful" speakers aren't necessarily lower in resistance... you can't make an equation there...
if you think the mcacc stuff is a lot to learn (and there's no doubt that it is, i certainly haven't mastered it and i've been using it on pio avr's for a long time), just wait until you start investigating speaker design/theory...
