The only reason I "disagree" with Todd above is...
1. In your Denon you are going to have to set the crossover of your center/surrounds at 200hz. If those HTiB sats will even handle 200hz.
2. Provided they can work on 200hz, the Deon, should...for a while, be able to withstand the 3ohm load...because it isn't 3ohm on all 5.
Also, keeping in mind what I said prior about PMPO power. Those speakers(no I haven't tried to find them online...and I'm not going to bother) probably only handle a "real" 15 watts.
15 watts is probably not all that loud, considering how low the efficiency is of them. Put it another way...
Those AJ(last I checked and if memory serves) are 87db efficient. I would be shocked if those Panny HTiB speakers are any higher than 75db efficient.
Meaning, if you are feeding 1 watt to those AJ, the center/surround need 15-18 watts.
In other words, you won't be able to turn it up much.
