We have a through lounge diner, dining room was completely updated earlier in the year with bi-folds to the garden fitted, currently doing the lounge and hope to have it all finished in time for Christmas. I've installed two Sonance TL622R speakers in the dining room ceiling and two more in the lounge ceiling. These speakers were left over from my cinema build and this seemed like a great use. The lounge will have a 5.1.2 speaker set up, which I'm sorry to say I'm just going to use the existing speakers which are Sony MS535. They fit in well, they've been there for a number of years so the wife won't complain, I'd could do without the expense of a new set and frankly the wife/daughters won't appreciate the difference - I have the cinema room I'd like to use all four ceiling speakers when we are playing music, and the Sony's and the two lounge ceiling speakers for Atmos. The system is pretty much used for TV viewing, so any Atmos will be upscaled (if that's the right word). What options are there at the cheaper end of the market that will cope with the above speaker connections and the way I want to use them? I'd prefer a system that could handle 4K for future proofing although not essential.
