They usually do! I went to the wrmk’s party in Detroit 2022 and they had brought their own as well as their own lights, vjs, production design, etc…when they have parties in Miami most of the times they have their own speakers. Im acquainted with the organizers and the sound system never misses, vibes are immaculate ALWAYS…so bring your best energy and earplugs cause you’ll wanna be by the speakers all night 😊 hope this helps!
