About to meet owners of a new Yoga studio to talk about sound. I imagine they are going to want to teach a class and be able to talk on a microphone to participants.

So far I think they will need a wireless mic, mixer and a couple of speakers. Room is about 20' x 30'.

Looking for suggestions on equipment and speaker placement. What I had in mind.

-Shure wireless headset system
-Small mixer
- 2 JBL powered speakers on wall

Is there a simple powered single line array speaker that can be placed high in the room that might create more clarity and better coverage in a room. What about one of those JBL line array column/subwoofer systems that street buskers use? That could be an easy solution that includes a mixer with bluetooth. I've heard that these line array columns are less prone to feedback, which would be a bonus.
