StudioLive® 18sAI Active Integration subwoofers from PreSonus are designed to complement full-range systems without overshadowing them. Driven by 1,000W RMS of Class D amplification, the 18sAI’s 18-inch ferrite speaker delivers exceptional low-end performance down to 35 Hz (-6 dB). With studio-monitor accuracy onstage and unprecedented onboard processing and networking features, the net result is a musical approach to sub-bass frequency reproduction that affords a natural listening experience on a large scale.

Powerful and musical, the 18sAI naturally extends low-frequencies with a fast and accurate transient response. This sub is a perfect mate for StudioLive 312AI, 315AI, and 328AI full-range loudspeakers, making it an ideal choice for installations and mobile applications where fidelity matters. For applications that require a more linear (“flat”) frequency response between the subwoofer and full-range speaker, engage the highpass filter on the full-range StudioLive AI-series loudspeaker to readjust the phase and time-alignment, keeping the full-range system in phase with the 18sAI subwoofer.
