How do I multicast my Bluetooth speakers on my iPad. I have two speakers which I would like to play simultaneously Is there a way ?

There are some brands of speakers that provide an app that will let you work around this limitation. However, both speakers generally have to be the same. And, of course, they have to be a brand that supports this. UE is one that I know of.

Bluetooth allows only one pairing to a sound output at a time.
