Hi Nick.2003,

unfortunately, that's impossible.

Sony Support EN

Not to my knowledge; the subwoofer is wireless and is connected directly to a system (soundbar, etc.).
It is not found via my Sony TV. But why you only want the subwoofer makes no sense to me, sorry.
a bit senseless. The whole thing only makes sense with a soundbar or surround system.
If you want sound that's better than a soundbar, I recommend the Sony HT-A9 surround system.
(4 speakers and a control unit that is connected to the TV via eARC). Here you can also integrate the subwoofer.
subwoofer. It sounds HAMMER... I am not an employee of digitec.ch, but a private customer. I clearly speak a
recommendation for the SA-SW5 and the Sony HT-A9. I wouldn't want anything else.
I also bought the HT-A9 here.
Best regards from Bern.
