This speaker is great for speeches, it performs well outdoors, it can be heard very well in a crowd of 200-300 people. Music also sounds good, but you'll probably want a stronger speaker for music. The average power consumption for playing rock music is around 50-60W at its maximum level, and this is pure RMS power. Everyone who owns a 50W guitar amp knows that this is A LOT. The sound is very clean and it spreads pretty evenly in space. Be aware that it does NOT have a battery. I have only one negative remark: the bluetooth receiver has a pretty weak range compared to some other bluetooth speakers. You should keep your phone or PC close to it (not more than 5 meters away) to avoid drop-outs. All in all, excellent speaker.
