It will drive them all day, years in, years out. As with any receiver, just make sure to give it proper ventilation.
Joseph, Not only is Paul correct, but the H/K will probably run your 4ohm speakers better than almost anything out there at it's price point. You have no worries.
but the sound is too clear i dunno maybe i have to try onkyo or denon my hk avr120 sometimes isnt to my liking i dunno why!! Maybe cuz it gets too damn hot.
I contacted HK support about driving 4 ohm speakers with my avr 210 and they said do it only temporary and it would decrease the life of the receiver. But in their FAQ on the site it says you can use it for 4 ohm. BOb
As the 210 has 50Wx2 and 40Wx5 @ 8 ohms, the expectation that it will double down for 4 Ohms is on the fringe. So I am not surprised by the H/K tech answer. I did not have this expectation even with my 310 (60Wx2, 50Wx5 @ 8 Ohms). The 510 I now use is expected to do this, however (80Wx2, 70Wx5 @ 8 Ohms)) without breaking a sweat. As the 520 has even more power, it's capabilities are not in question.
