Acoustic Sound Design via Amazon offers the Denon 7.2-Channel 4K Ultra HD Network Receiver bundled with the Harman Kardon HKTS 15 5.1-Channel Home Theater Speaker System for $449 with free shipping. That's $235 under the lowest price we could find for these items sold separately elsewhere. (Most retailers charge this price for the receiver alone.)

The receiver uses the Audyssey MultEQ XT automatic room acoustic measurement and correction system and the supplied microphone to match your speakers to your room's acoustics. Features include 95 watts of power per channel, 4K and 3D pass-through, Dolby Atmos and DTS:X support, 802.11n wireless, Bluetooth 2.1, AM/FM tuner, USB, and eight HDMI inputs. The speaker system inlcudes four satellite speakers, a center-channel speaker, and a 10" subwoofer.
