Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

2-channel (stereo) Bluetooth audio to 2 speakers possible?
connecting a bluetooth headphone to an iPad transmits 2 channels I guess. But a headphone is a single device. Is it possible to connect two identical Bluetooth speakers (JBL Eon One), one for the left channel, one for the right channel? I can connect to either one, but not both. Is there an app that can help?

Anker has an app for some of their Soundcore speakers, and I’ve been able to connect a pair of the Flare+ to do this. I don’t know of an app for any other brands though...
I believe Bluetooth V5 can support dual output but it would need to be supported on all devices, and you would need an app to support it also.
Would be very easy with the right cable but then it wouldn't be wireless...
Maybe you're looking for a so called Bluetooth splitter? Something like this: https://amazon.com/TaoTronics-Bluetooth-Transmitter-Receiver-Simultaneously/dp/B01EHSX28M/ref=sr_1_3?keywords=bluetooth+splitter&qid=1553824714&refinements=p_72%3A2661618011&rnid=2661617011&s=gateway&sr=8-3
