FLM-18
18” Front Loaded Horn (Modified)
Compact in footprint, uncompromising in output—the BPM Audio FLM-18 is a single 18” front-loaded horn subwoofer designed for precise, musical low-frequency performance with professional-grade reliability. Featuring a modified horn architecture, the FLM-18 delivers tight, punchy bass with excellent transient response, while addressing one of the fundamental limitations of traditional front-loaded horn designs: driver cooling.
Through innovative internal airflow management, the FLM-18 ensures significantly improved thermal dissipation, allowing the driver to operate at optimal temperatures even under sustained high-output conditions. The result is enhanced reliability, reduced power compression, and consistently powerful performance throughout your event.
Tuned for maximum efficiency in the 35–120 Hz range, the FLM-18 offers the speed and articulation of a front-loaded design with the projection and dynamic impact of horn loading—perfect for touring systems, club installs, and scalable PA rigs.
