I am looking to wall mount my LG B8 65" OLED at eye level with a glass cabinet below housing my Sky Q box, Amplifier and Blu Ray player. My existing centre speaker works fine but if I sit it on top of the cabinet, or wall mount it below the TV, I would have to have the TV a bit higher than I would prefer. I only have a maximum height gap of 11 cm to play with, otherwise the TV would have to be mounted higher. I can't find any centre speakers to fit. Ironically, most sound bars would look perfect in the space available but I already have a 5.1 system. I don't know much about sound bars but I am assuming they cannot be used as a stand alone speaker to replace a centre speaker. If they can be used in this way then that would be the perfect solution! Otherwise are there any centre speakers with similar dimensions to a sound bar? Any suggestions would be very welcome.
