One Soundbar + Two Surrounds + Subwoofer

On this website, 3.1 home theater systems include one long soundbar speaker (instead of three separate front left, center channel, and front right speakers) that goes beneath your television screen, two side/rear surround effects speakers, and a subwoofer to handle the lowest frequency bass.

• The Yamaha YHT-494 home theater audio system pictured to the right includes an HTR-3063BL receiver with four 3D-ready HDMI repeater inputs and A/V switching, although it doesn't upscale non-HDMI sources via HDMI output.

• The Sharp BD-MPC41U system pictured to the bottom right features an integrated non-3D-ready Blu-ray Disc player, but lacks A/V switching.
