this review may be premature as I have be use this product only for a week . however , some thing immediately stand out : 1 . it do NOT produce surround sound and it be not mean to . so do not be fool by the `` Air surround extreme '' kinda jargon . you will clearly hear sound come out of the speaker bar and that be about it . do not expect sound to bounce off the wall and come at you from the side or from behind you . I be use a optical cable to connect the tv to the receiver . not sure hdmus would make any difference . 2 . the receiver be simple and the build in subwoofer have solid bass performance . I have to bring the bass volumne down to 1 to keep it manageable . this be where you will feel it when watch a movie . it do a excellent job of amplify low frequency without distortion . 3 . unit work with tha harmony 700 remote . 4 . you will have to run setup and crank up the center speaker volume to be able to hear human voice , else they get subdue by the music . out of the box , I could hardly hear actor speak . change to the center column to a 5 or 6 -lrb- max -rrb- do the trick . I be impressed by the sub , but let down by the bar speaker - they sound exactly like desktop speaker . it be a $ 300 system and sound like one . if you be on a budget , I would recommend it . if not , keep look .
