#3 Can you can pair two thump 12bsts together without using the app?
You can connect them together right from the control panel on the speaker as well as decide if you want dedicated left and right speakers, HOWEVER, only a Bluetooth source can then be shared between the two in this config...the inputs on one speaker do NOT go to the other over wireless in my experience...which I would LOVE for that to be the case. As the previous answer noted you can simply take the output of one speaker and use an XLR cable to put it to an input of the other.....but that also eliminates L/R and give you 1 channel basically...same as if you put the speaker into wireless zone mode using a Bluetooth source.
