Bluetooth speakers for Raspberry Pi?

Question

Bluetooth

I want to buy a raspberry pi B + to build a "home theater". R-Pi will take movie from a network drive via Wi-Fi and send a video signal to the projector via HDMI. Actually, the question is: I need to transmit sound to the soundbar using bluetooth, is it possible to do this? Of course, I will purchase both a dongle and a wifi adapter, but is it possible to make all this work without sophisticated dances with a tambourine, because with Linux I'm on "Oh, look, is that you?"
PS The projector will be in a "mobile" box, along with Raspberry, and not bolted to one place. That's why I want to get rid of all the wires except for the power wire.

I think this article should help you . Unfortunately, I can not check due to the lack of an adapter. Can you tell me which adapter you have?
