Professional portable and installed plastic loudspeakers where high sound quality is required. Can be used in applications including sound reinforcement in Front of House and Foldback applications in Houses of Worship, Events, Clubs, Rehearsal Halls etc. The S Series is suitable for music and vocal reproduction in demanding applications.　The cabinet is made of high strength plastic material with excellent weather resistance. The special coating process makes the cabinet surface scratch-resistant and corrosion-resistant. The selected polyester damping material effectively absorbs cabinet standing waves. The built-in crossover circuit and different voltage outputs provide users with more options. Aiming at this special cabinet, the transducers used are optimized by our experienced engineers, who focus on the magnetic system and vibration system. To get excellent performance, the engineers take a lot of advanced technology to decrease the magnetic impedance and lower the magnetic leakage, without increasing the transducer weight.
