My partner is hard of hearing and our flat is open plan so the layout is front room > lounge > kitchen. all this is one big open space. He does a lot of office work in the kitchen.. yea I know (even though he has an office, but never mind that) he keeps saying he wants to hear the tv from any point in the room and it's hard to hear the tv past the lounge and can't hear anything in the kitchen without the tv being on full volume. would it be possible to just hook up a 4 maybe 6 speaker system to the tv so the sound is extended to cover the whole room? how would I go about this? I was thinking of getting the speaker system they have in big open venues or pubs so the music/voice can be heard in the whole room but I can't remember what the system is called. I have told him about open-loop systems and he's not keen on them.
