I recently bought an onn. 24# Class 720P HD LED Roku Smart TV (model - 100012590). This is my first Smart TV and I need to purchase the Roku Speakers, since they are the only ones compatible with the Roku TV. I am used to connecting audio through AV cables - but I noticed the Roku speakers do not have AV cable. My TV does not indicate that it has Bluetooth technology, so how would the Wireless Roku speakers connect to my TV?? I apologize if I sound naive... Is the wireless technology built into the TV? And is the wireless tech different than the Bluetooth tech?
