The Atlas A-Line ELW110A-B low frequency speaker system is ideally suited for use in speech and music reproduction applications when used in conjunction with an EL1503-B full range line array speaker system. The ELW110A-B includes a single 10" low frequency driver in an optimally designed and constructed enclosure. The ELW110A-B includes 200W RMS class D amplifier that includes onboard DSP. The ELW110A-B is designed to provide power to an EL1503-B in a single ELI line array system and includes all necessary hardware to make this connection. The ELW110A-B will also power a second passive low frequency speaker, model ELW110X-A, and second EL1503-B in a dual line array application.
