The PreSonus StudioLive 18sAI Active PA Subwoofer is a high-quality and versatile 18” subwoofer offering remarkable audio precision and punch in a sleek unit. When used with a StudioLive 312AI, 315AI, or 328AI, the StudioLive 18sAI subwoofer forms a true four-way system. But the StudioLive 18sAI is flexible enough to work great with other powered loudspeakers too.
How low can you go? With the StudioLive 18sAI active PA 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.
