The CX1423SA is a professional 900W active line array subwoofer designed to provide powerful, deep, and controlled low-frequency reinforcement for professional sound reinforcement systems. It is engineered to complement compatible full-range line array speakers by extending the system’s bass response and providing the additional low-frequency energy required for music, live performances, entertainment, and large-scale events. The active configuration incorporates built-in amplification, eliminating the need for a separate external power amplifier for the subwoofer. This makes the CX1423SA a convenient solution for professional audio systems where quick deployment, simplified cabling, and efficient system configuration are important. It can be connected to compatible mixers, DSP processors, audio controllers, and line array loudspeakers as part of a complete professional sound reinforcement setup. The CX1423SA is designed to deliver strong low-frequency output with the control required for demanding professional applications. When combined with compatible full-range line array speakers, it helps create a more complete and dynamic sound field by allowing the main array to focus on mid- and high-frequency reproduction while the subwoofer handles the low-frequency spectrum.
