I have connected a Bose soundbar. Works tip top

The speakers are matched to the original soundbar from LG. It says: Compatible with the SK10Y, SK9Y and 2019 SL series soundbars.

But on the other hand, they are w-lan speakers and if they recognise TVs, linking is possible.

I don't think so, because originally they were only suitable for pairing with the Meridian SLP 8-9 and 10 soundbars.
