If you can direct me to a resource that already covers this, please do.

I have a dumb TV, namely LG 5900. No Bluetooth. Optical audio output. I need more speakerage. I'd like a soundbar and wireless sub of moderate price. But I don't understand this part ....

Does the sound bar have the Bluetooth transmitter for the sub, or must the Bluetooth signal come from the TV? Am I making sense? Can I have a Bluetooth sub if I have a dumb TV? Will the sound bar provide the bass signal to the sub?

Thanks for any help!
