I am in the same boat as OP. I just moved into a new house and I will setup a home theater in the basement. In my family room, my wife wants a clean look. I have a cabinet and the TV sits on top. Under the TV, there is a slot (5" high) for a STB or soundbar. We are streaming everything so I don't have to worry about a STB. I'd like to place a soundbar inside. Therefore, directional sound won't be possible, but it's okay since the basic idea is to amplify and add some depth to the poor sound from TV during broadcasts and a few movies. I'm not looking for miracles, but I would like to add volume and depth. The wife couldn't care less about sound quality, only aesthetics. I care about sound quality, but I know we will be limited by aesthetics. So I'm looking for a good sounding soundbar without a sub and with no concern for directional audio. I saw some suggestions for the Q Acoustics M4 Soundbar. It might do the trick, but I'm willing to look/listen to anything at any price. I just think the price might be wasted by limiting my placement requirements. Any guidance from this group would be appreciated.
