Presonus Active Integration Subwoofer

You can get pretty darned low—down to 35 Hz (-6 dB). Better yet, the 18sAI’s 18-inch ferrite speaker delivers those lows with an accuracy usually found only in studio monitors—except a whole lot louder (up to 135 dB SPL), thanks to a 1,000 watt (bridged), Class D power amplifier. It adds up to punchy, round-sounding lows that make kick drums, basses, and other basement-dwelling sounds come alive.

When used with a StudioLive 312AI, 315AI, or 328AI, the StudioLive 18sAI forms a true four-way system. But the StudioLive 18sAI is flexible enough to work great with other powered loudspeakers, too!

With most 4-way systems, leaving frequency content below 100 Hz in the full-range loudspeaker can introduce cancellation and reinforcement with the highest frequencies that are reproduced by the subwoofer.

StudioLive AI-series loudspeakers avoid this problem when combined with an 18sAI subwoofer. For applications where a frequency overlap at 100 Hz is beneficial, you can achieve bigger bass sound without any extra effort. For applications that require a more linear (“flat”) frequency response between the subwoofer and full-range speaker, simply engage the highpass filter on the full-range StudioLive AI-series loudspeaker. This will also readjust the phase and time-alignment to keep the full-range system in phase with the 18sAI subwoofer, enabling you to create the best four-way system for your application.
