Live sound speakers are a cornerstone of live audio setups, used to amplify sound for audiences at concerts, theaters, and events. They have evolved from simple loudspeakers to highly specialized, robust devices designed to deliver clear, powerful sound at high volumes. Significant brands include JBL (SRX series), QSC (K series), Yamaha (DXR series), and Electro-Voice (ZLX series). These speakers are used for a variety of live performances, from small club shows to large outdoor festivals, and are often paired with mixers, amplifiers, and other audio equipment. They are engineered to handle the demands of live sound, with features like durability, high output, and wide frequency response.
