Our current tv is a 82 inch Sony OLED and within a few years it will grow to approx 100 inch and not necessarily a Sony.
Our current sonos eArc sound bar plus a sub, which obviously does not give much left/right separation relative to the screen width. It will be even more inadequate when ever the 100inch arrives, maybe in two 2 years time.
We are prepared to spend a few $k to upgrade the existing TV to add 2x rear speakers and 2x additional front side speakers, is this technically feasible? Could this arrangement work with larger TV.
The goal is to improve immersive quality now (with rear speakers and improved stereo front separation) and so have the audio setup established for when the larger TV arrives.
We are also prepared to scrap Sonos (ekk) and start from scratch when the larger TV arrives, but are hoping there is a reasonable Sonos solution that will bridge both TVs.
You could consider this is a home theatre setup as the room is dedicated to chilling and the tv, it is somewhat open to a living kitchen dining area and has two walls with large windows. Whacking a gazillion amps into speakers is not part of the family culture (sigh).
Current viewing distance is 3 meters, which will remain for the 100 inch. It is 3 meters behind couch to the rear wall.
I'm not convinced that any hi tech built in tv speakers can be relied upon for separation, ie the tech that identifies the position of action/voice on screen and directs sound from that section of the screen.
Cheers!
