[Discontinued] PreSonus StudioLive 18sAI 1000W 18" Powered Subwoofer Active Integration Stage Subwoofer PA System

PreSonus StudioLive 18sAI 1000W 18" Powered Subwoofer Active Integration Stage Subwoofer PA System

Tight, clean, natural bass.

Designed to complement full-range systems, without overshadowing them, the StudioLive 18sAI active subwoofer naturally extends the reach of your full-range systems’ low end to deliver studio monitor accuracy throughout its range. 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. The net result is a musical approach to sub-bass frequency reproduction that affords a natural listening experience on a large scale.

A four-way PA that works as one.

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.

You’re in control—here, there, and everywhere.

The StudioLive 18sAI subwoofer features a robust onboard loudspeaker processor that can be accessed and controlled over a standard LAN network. PreSonus’® SL Room Control software makes customizing your speaker system as simple as connecting an Ethernet cable to a wireless router. Creating a cardioid subwoofer array is as easy a pressing two buttons, thanks to onboard polarity reverse and three alignment-delay presets.
