Bob - The QN84A TV features 40 Watt 2.2 Channel sound. The QN84A also features Object Tracking Sound Lite which virtually tracks objects moving across screen and strategically places sound around you. The QN90A features 60 Watt 2.2.2 Channel sound as well as Object Tracking Sound Plus (OTS+) which utilizes 6 speakers to place sounds exactly where they appear on-screen and optimizes sound based on each scene. Another benefit gained when stepping up from the QN84A is Ultra Viewing Angle which makes every seat in the house a great one. Engineered to reduce glare and enhance color, this feature delivers a vibrant picture no matter where you sit. ^Gina
