" ... WOW, makes a monument difference especially with a sub bass ... "
" ... The bass kicks and trebel fills the room. ... "

" ... Does not work with Arc or CEC - you have to have a second controller to turn volume up/down. ... "
" ... Not only is it not as loud as the previous generation - it is actually shorter - the buttons are pressed against the TV when mounted a certain way. ... "
" ... Partially because the LED light settings being dumb but mainly because STATIC. ... "
