HW-S61D

I listen to the similar stuff. S60d. Excellent sound. I think it's 200 watts I also have a subwoofer SWA510 and 9200s. But not necessary.

Don't buy a soundbar just because it's the same brand as the TV, I tried Samsung's Q-symphony and it's ass. I also switched to a Sony TV while keeping the Samsung soundbar.

Yes can, i know people with have the same situation and have All In One soundbar, which is not probably the best from Samsung, but working good. Samsung Q-Symphony on TV working in this perfect too. Sound can be around you, effect is amazing. Just add soundbar from TV about 1 metre distance and have to be cool effect with specific material of video. Humans which have this situation have smaller room than 12 squares metres. You probably will be need better soundbar as S class 60 models.

Buy samsung q-symphony soundbar so you will have the option to combine internal speakers with soundbar, which is awesome.
