Hitachi’s HSB32B26 Bluetooth Sound Bar fulfills both of these purposes. It is totally self-contained in that there is no subwoofer accompanying it (although there is an output for connecting one, should the home owner have it already). Wiring is also kept to a minimum, since the sound bar has built-in Bluetooth capabilities for streaming audio from sources such as mobile devices. Physical connections are kept to a minimum, as other than a power supply input, there is only the choice between coaxial, digital optical and analog L/R RCA audio inputs.
The Hitachi HSB32B26 Bluetooth Sound Bar also has a sleek and non-intrusive appearance (piano black) that can compliment its placement beneath a wall-mounted display or placed in front of it if the TV is on a cabinet. There are two brackets attached to the bottom that serve as feet. These can be removed and screwed onto the back to serve as wall mounts. The sound bar’s lightweight nature (6-1/2 pounds) means that very little difficulty will be had in wall mounting on drywall/plasterboard (but care must always be taken as regards electrical wiring that could be inside the wall).
