JBL introduces the new Commercial Series affordable loudspeakers that provide excellent performance for paging and background music applications including retail stores, restaurants, schools and other public facilities. High sensitivity ceiling speakers provides maximum sound level even at low tap settings, and wide dispersion ensures excellent coverage. Triple voltage transformers (100V, 70V and 25V) are compatible with any distributed speaker system, and the Commercial Series meets UL1480 and UL2043 requirements for use in plenum ceiling spaces. The drivers all feature a full 25 mm (1 in) diameter voice coil with a Kapton™ coil-former and high-temperature wire for superior power dissipation and long-term reliability. The driver, grille and transformer come pre-assembled for ease of installation. Accessories include matching Commercial Series pre-install back cans and tile rails. The surface-mount speaker is versatile, able to operate with 100V or 70V distributed speakers systems or in 8 ohm direct mode. It produces full-range sound quality for foreground or background music applications.
