PA speakers are not designed for production and mastering. They’re designed to go loud. If bass is important to you then a sub is needed. 100 people absorb alot of sound.
That’s why you want quality jbl loudspeakers with easy to get parts when broken. Behringer has horrible service, so buy from a good dealership. Behringer have reasonable sound but can die on you anytime. Parts are hard to get. If you push these speakers a bit, there’s a audible hiss, but it won’t get better. 50-60 people you can manage with these speakers as long as you don’t push them too hard.
i have the JBL EON 615 1000 Watt Powered 15″ Two-way Loudspeaker System with Bluetooth Control . I love ’em. They’re the ones that are top sellers. Never had any complaints, except from the neighbors.
