Nope. That's not the spec you're looking for. What you highlighted just tells you the impedance of your high-level inputs (the RCA jacks). There isn't really a spec you can turn to about the capability of driving 4 Ohm speakers unless they tell you outright, with a spec like:
Continuous Average Power (FTC) per Channel : 180 Watts per channel, 20Hz – 20kHz, @ <0.07% THD, both channels driven into 4 ohms
Since the specs for 4 Ohm speakers aren't listed, it seems as though H/K doens't officially rate this amp to drive a 4 Ohm load. This doesn't mean it cannot do it, though.
