Funniest thing is I went to a small office and it sounded good. I asked what they are using.
It was a JBL portable $99 (? - maybe less) thing. It was sitting on a shelf.
These days if you mount a few $10 shelves and sync up a few of these $60 portable speakers it gets the job done.
They simply put it to charge at night and run it all day. It sounds perfect for the space. Mostly bass emphasized and rolled off highs. Just the right balance and people can comfortably converse.
No wiring, no power point, no contractor needed.
Isn’t modern technology great?
