I'm not sure how to answer that. I bought two for a party in a room I rented in a restaurant. There were about 60 people in the room, talking, visiting, and eating. The music was loud enough to be heard but not so loud it drowned out conversation. When I use them at home, I don't turn them up all the way. You can link up to 10 through the Bluetooth feature to get more sound. We are thoroughly pleased with the purchase.
