What Speakers to use in a bar/restaurant environment

I'm looking for advice as to what speakers I can install on the walls or suspend from the ceiling of a bar/restaurant. The current ones sound lousy, not clear at all, compared to what I would like. There are many 70/100 Volt systems on the market, and I assume they make quality speakers at a sane price level.
I'm looking for mainly background music, but I need the ability to get suitable volume for events like a UFC.

Would it be worth considering smaller home audio speakers for this type of environment, or do I need to install "commercial" ones such as those made by JBL, etc?

And advice or direction will be helpful.

The rooms are ~3000sq ft, with a 14 foot ceiling.
Want to get a very nice quality of sound with low /moderate volume .
