PreSonus StudioLive 18sAI 18-inch Active Subwoofer w/Active Integration Technology

Although the StudioLive 18sAI is flexible enough to work great with other powered loudspeakers, when used with a StudioLive 312AI, 315AI, or 328AI, the StudioLive 18sAI forms a true four-way system. 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. Need a little more bump? Leave the highpass filter off and enjoy the perfectly phase- and time-aligned overlap at 100 Hz between your full-range system and your subwoofer.
Whether out on tour or installed in a venue, the StudioLive 18sAI subwoofer mates perfectly with StudioLive AI full-range loudspeakers to deliver studio-monitor accuracy at incredibly high SPLs. With extensive software control and wired and wireless networking, it offers advance capabilities that go well beyond conventional point-source loudspeakers, yet its easy to set up and use. Check out the StudioLive 18sAI at your favorite PreSonus dealer.
