For optimum sound quality across all channels, the AVR-X4100W features a sophisticated power amplifier section with all 7 channels configured identically employing discrete high-current-capable power output devices. Each channel is rated at 125 watts (8 ohms, 20Hz to 20kHz, .05%THD), and all channels are able to safely drive lower impedance speakers down to 4 ohms. The advanced Eco amplifier mode adjusts power consumption according to signal level, and there's an on-screen Eco Mode display that lets you see the power consumption reduction in real time.

With the AVR-X4100W's dual subwoofer outputs, you can connect two subwoofers, and place them in different parts of the room, and enjoy smooth and accurate deep bass response.
