My .02 worth...
Send the 3 Bluetooth speakers back to the store, or wherever you got them,
then buy a home stereo system that accepts blue tooth signal (From your tablet
to the stereo), then from the home stereo, you can add a bazillion wireless
speakers wherever you want in your house.
IF you want to take the speakers with you portable, find a "hub" that will hook
via USB or Blue Tooth to the tablet and then you are set.
Just a thought, maybe you're going about this in the wrong direction,
maybe you need to re-think the hardware, not the software?
Good luck!
Peace!
