The wireless link is usually just for the model bar and rarely is used on a new model. Even more so after a decade.
Now a good technician could convert it into just a sub to be driven with some amp or receiver but I do not expect a new sound bar to talk to this old wireless sub.
So my lg hlb54s sound bar died after 10 years, the amp board is buggered, my question is the wireless sub woofer that paired with it, can it be used with any other LG soundbar? I would hate to toss it so just seeing if these subs are compatible with anything else
