Yamaha on Monday announced the availability of four new home theater systems, including the flagship 7.1-channel YHT-791BL. It includes a 90W-per-channel HTR-6250BL receiver. The receiver has four 1080p-compatible HDMI inputs, HD Audio internal decoding and Bluetooth compatibility. There is also a pair of front speakers with 6.5-inch woofers and 0.75-inch tweeters, a center channel with two 3-inch woofers and 0.75-inch tweeter as well as four satellite surround speakers, each packing a 3-inch driver and 0.5-inch tweeter. A 100W, 10-inch subwoofer provides the low bass, and the company's iPod dock, the YDS-11SL, is included with the $850 system.

Next up, the 5.1-channel Yamaha YHT-591BL is powered by the company's HTR-6240BL AV receiver with a 105W-per-channel amplifier and otherwise similar functions and connections to the HTR-6250BL receiver from the flagship system. Each of the three front and center speakers includes four 2.25-inch woofer and a 0.75-inch tweeter in each of them. The two rear satellite speakers have two 2.25-inch woofers each and a 0.75-inch tweeter. A 100W, 10-inch subwoofer completes the $650 package.

The YHT-491BL has a HTR-6230BL receiver that supplies 100W to each of the five speakers as well as the 8-inch subwoofer. Included in the $550 bundle is the company's NS-SP7800M speaker package without the subwoofer that comprises of two front tower speakers and smaller components that house two 2.25-inch woofers and a 0.75-inch silk dome tweeter.

Last and technically the least, Yamaha's YHT-391BL system uses the same receiver as above, though pairs them with two-way satellite speakers, each packing a 2.5-inch woofer and 0.5-inch tweeter, with the center channel adding an extra 2.5-inch driver.
