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. But that’s just the start!
