Real Sound MS-18B18 Inch PassiveSubwoofer

Real Sound MS-18B 18 Inch Passive Subwoofer - an 18-inch passive subwoofer for large PA systems, providing powerful low-frequency reinforcement when driven from a suitable external amplifier.

The MS-18B houses an 18-inch driver in a vented bass-reflex cabinet designed for high-output subwoofer performance in live PA systems. As a passive subwoofer it requires an external amplifier - a dedicated subwoofer amplifier or a separate amplifier channel in a biamplified system. The 18-inch driver delivers the deep, authoritative bass needed for live music events, clubs, outdoor concerts, and venues where strong low-frequency presence is required.
