I am deciding between 2 H/K receivers. one plays 120 watts per channel, the other 80. the room for this receiver is about 13 x 20. what does this statement mean and how should it affect my decision
"80 Watts per channel, 20Hz – 20kHz @ both Channels driven into 8 Ohms OR 100 Watts per channel, 20Hz – 20kHz @ both channels driven into 4 ohms "
