Passive subwoofers are designed to reproduce low frequency bass within live sound systems and require an external amplifier for operation. They enhance the overall impact of music and performance audio by delivering the deep bass that full range loudspeakers cannot produce alone.

Commonly used for DJs, live music, events and performance venues, passive subwoofers work alongside main speakers to create a fuller and more powerful sound system.

If you need assistance selecting the right passive subwoofer for your system, contact our team and we will be happy to help.
