The Sub218L is a low profile, dual 18 inch vented subwoofer that is designed to provide extended low frequency support in a wide variety of installations. Its premium, high power transducers are physically engaging, yet are musically articulate enough to reproduce the subtlety and harmonic nuance of an upright bass or the low strings of a piano.

The Sub218L requires digital signal processing, and many platforms are supported. The Sub218L is an excellent option any time a subwoofer with robust SPL capability is required to fit under a short stage or similar structure. This makes it the perfect choice for large houses of worship or theatres, live reinforcement or dance systems, high intensity DJ monitors, A/V screening rooms, and distributed low frequency reinforcement in nightclubs and theme parks.
