Any active speaker of any make can accept a signal from this device via Aux out. The MAA2-AW from Appaudio streams audio from line level audio sources to smart phones and tablets over Wi-Fi.
Does Bose have anything that can do something similar?
I'm thinking Bose earphones connected to a smartphone at a live venue for example.

Ok. I did a bit more research and found that although the Appaudio approach sounds like a good idea streaming from line level audio sources to smartphones is very difficult to support. This is probably one reason manufactures are tending to remove the 3.5 mm audio jack from newer versions of smartphones. 
Comparing reviews for Bose SoundTouch (https://play.google.com/store/...ndtouch&hl=en_AU) and AppAudio (https://play.google.com/store/...ppaudio&hl=en_AU) gives you an idea of what I'm talking about.   

Hi Uncle John,

I'm sorry you haven't received a response sooner.

Bose doesn't currently have a product that has this functionality.

That's an interesting idea for delivering audio through a different means.

So I bought a SoundTouch Wireless Link Adapter and two SoundTouch 10 speakers. The adapter (LecternR001) takes an "aux in" signal and transmits it to both SoundTouch 10 speakers (Cry Room and Foyer).
This setup works well except for one problem, the two speakers lag the adapter by about 3 seconds.
How can this be remedied?

I just set up a SoundTouch Wireless Adapter and some remote speakers to replicate your set up.

Unfortunately, using the Bose SoundTouch Wireless Link Adapter Aux input introduces the lag (latency) between the sound source presented to Aux input and loudspeakers connected locally or in your case remotely. This happens as the signal sent to the SoundTouch Wireless Link Adapter audio output is synchronized with the external loudspeakers connected over the wireless network.

This latency is not noticeable for recorded music (this is the intended purpose of the Aux Input). 

For live sound applications, you will notice the latency when you can hear both the live sound source (e.g., a talker at the lectern) immediately, and the remote sound (e.g., Cry Room and Foyer).  You probably won't notice the latency if you can't see or hear the talker at the lectern. If you can isolate the rooms (close the doors), the latency should be less noticeable.

I'm sorry there isn't an all Bose solution for the latency. Any other approach that comes to mind would likely be more expensive.

For example:

Bose S1 Pro systems for the Cry Room and Foyer
You would also need low-latency receivers

Instead of using the Bose SoundLink Wireless Adapter, you would need a different kind of transmitter to connect to the low-latency receivers in the Cry Room and Foyer.

The kinds of transmitters and receivers I'm thinking of here are relatively new in the market (last year or two) that operate in the 2.4 GHz frequency range. Some people are pleased. See Wireless transmitter/receiver to use with two S1 pro speakers. Others have reported latency issues.

Another approach is to use different wireless broadcast technologies with greater range and more channels. Here is a link to some systems from Shure

Thank-you for your explanation. We'd really like a system that would also cater for the hearing impaired sitting in the main auditorium. This would require a low latency system. Thankfully Bose devices hold their valued very well. I bought used devices and can reasonably expect to sell them for the same price I paid.
With the latency issue in mind I did a little more searching and found a product from Listen Technologies that uses smartphones in the way I described in my OP. The two channel server appears to be excellent value (latency: 40ms-120ms) and ideally suited to meet all of our requirements:

I noticed that the embedded images for my 2/8/20 post are missing and thought readers might benefit from seeing them.
Here they are:

A SoundTouch 10 speaker would accept an Aux IN signal from an smartphone connected to the Listen Everywhere (LE) system referred to in my 2/9/20 post.
Of course a much neater solution could be achieved if Listen Technologies had an API which could enable a SoundTouch speaker to wirelessly connect directly to LE without the need for a smartphone to be permanently connected.
Would such an API ever be provided? I suppose only time will tell.....

Thanks for coming back to tell us you found a solution for your requirements.
