I am sure this WiSA Ready solution would be fine as a 2.0 channel setup (with the right speakers, that do not need a subwoofer for a better sound....whatever that would mean).
However this solution is meant for a tv!
IMO any external speaker solution for tv/movie listening should include a center channel (unless you are one person sitting perfectly in the phantom center spot).
That will not be possible - you will have to add the 2 surround speakers in order to add a center speaker.
My questions have revealed what I have heard from other sources = the setup of the 5.1 constallation is very basic.
When you know about the handles to taylor your setup you have with a multichannel processor (especially in a BSys4-based tv), you will miss something.....at least I will!
Furthermore you will have no possibility to easily swap between the different speaker constallations (like on e.g. a BV11 or Eclipse...).
It will not be possible to assign specific sources to a specific ‘speaker group’ - like 2.0/2.2 for a netradio source or 3.0/3.1 for regular tv viewing or 5.1 for movie/bluray content.
And you will not have the options that the True Image processing gives you for up- or down-mixing of the incoming sound material for adjusting to your specific speaker setup.
Or the automatic changing of Sound Modes depending on the content,, that you have there.
You will not have the option of making different speaker group for adjusting the sound to different seating positions (one person in one chair or a family in a bigger sofa.....).
Just to name some of what I’d miss.
If you can live without this (and more) you might be ok with what the WiSA Ready sw in the LG provides, it’s fine....
.....but you should at leadt think about it first - and don’t mistake it for a fully fletched B&O sound processor (or any other decent sound processor).
