@decryption ah thanks, I missed that second post. Your comment about going for a TV instead of a projector is interesting - my room is the same width as yours, but only 4m deep, so I didn't think I would want a big enough screen to warrant a projector, so had been looking at OLED/QLED TVs 85" or up instead, plus a Sonos system. Then I went to a hifi shop today and the guy reckoned this package (Epson TW-7100, 115" screen, same Polk speakers as you) would suit me fine... 🤔 https://www.westcoasthifi.com.au/packages/impress-home-theatre-package/
