Yamaha is back with the YHT-S400 sound bar which measures an impressive 31″ in length, although it stands all of just 2″ high while featuring an integrated subwoofer within the receiver to make it one of the more suitable tools for the urban warrior who retreats to his/her studio apartment den after a long, hard day at the office. With the integrated subwoofer, you no longer need to free up more premium space in your living room to enjoy quality audio. Another feature of the Yamaha YHT-S400 include UniVolume that ensures volume level remains consistent even when you go channel flipping. Expect it to retail for $599.95 each.
