Newegg offers the Yamaha 7.2-Channel 3D Network Home Theater Receiver with AirPlay (pictured), model no. RX-V677, bundled with the Polk Audio 300-watt 12" Powered Subwoofer, model no. PSW505, for $599.95 with free shipping. (The subwoofer will add to your cart automatically.) That's $40 under the lowest total price we could find for these items purchased separately elsewhere. (For further comparison, we saw this receiver bundled with a pair of floor speakers for the same price in September.) The receiver features 105 watts per channel into seven channels, Dolby TrueHD and DTS-HD Master Audio, 4K passthrough and upscaling, USB, WiFi, six HDMI inputs, and one HDMI output. The subwoofer features a frequency response of 23Hz to 160Hz, automatic on/off switch, magnetic shielding, adjustable crossover, phase switch, and volume control.
