The Mackie Showbox is a versatile portable PA with an impressive list of features that comes at an approachable price, making it another great pick for buskers who need portability plus versatility. If you’re in the market for the Goliath of portable PA systems, the Electro Voice Evolve 50 may be the PA system for you. This is mainly because I think portability is a more heavily weighted factor here than power—and what the S1 Pro+ lacks in power, it makes up for in portability, features, and affordability.
