Presonus STUDIOLIVE 18SAI 18" Powered Subwoofer

The StudioLive 18sAI is the powered 18" subwoofer in the StudioLive AI-series loudspeaker line. It is designed to compliment full-range StudioLive AI-series speakers while being flexible enough to work with other powered loudspeakers.

Interestingly, it incorporates more digital signal processing than any competitive full-range speaker on the market. This allows it to function as the final component of a true 4-way system when used with StudioLive AI full-range models.

The StudioLive 18sAI utilizes the same 2x500-watt bridged power amplifier distribution that powers the low-frequency woofer in the StudioLive 312AI, 328AI, and 315AI. It also features stereo inputs that, with analog pass-thru, can be summed mono.

The 18sAI features two DSP contours optimized for live performance and enhanced low end. It also offers three delay presets: 0m for use with a full-range speaker atop the sub; 1m for use with a full-range speaker on a separate speaker stand; and 2m for use with a full-range speaker on stage.

Advanced 24-bit floating-point digital signal processing.

Like the StudioLive AI-Series full-range models, the SL18sAI was tuned by master speaker designer Dave Gunness using Fulcrum Acoustic's proprietary algorithms.

This results in a truly "smart" subwoofer capable of DSP control of:

  • True 4-way integration with full-range StudioLive AI models
  • DSP-monitored temperature, over-voltage and excursion limiting
  • Multiple onboard delay setting to optimize the 18sAI with three common subwoofer positions
  • Three DSP contours

The robust onboard CPU in the StudioLive 18sAI makes possible an extensive set of control features for customizing and optimizing the system and for monitoring and fine-tuning performance in real time.

SL Room Control software provides the StudioLive 18sAl with wired and wireless remote control of:

  • Speaker delay
  • Mute and solo
  • Polarity invert
  • Output level

Output-level performance monitoring constantly provides information for:

  • Excursion limiting
  • Over-temperature
  • ADC clip detection

Other SL Room Control features include:

  • Network setup wizard and network scanning to automatically detect all speakers
  • Network browser
  • Group speaker management with mute, solo, and group graphic EQ
  • External Sub mode
  • Custom labels for each speaker
  • Preset save and load

All these DSP features are wirelessly controllable from SL Room Control for iPad, OS X, and Windows.
