Powered Sub with Active Integration from PreSonus!

    Big, powerful low end with the accuracy only found in recording studio monitors. That's what you get with the PreSonus® StudioLive® 18sAI Active Integration Subwoofer. Powered by an 1,000 Watt Class D power amplifier, the StudioLive 18sAI is housed in a rugged Baltic birch wood box, ready for road use or permenent instalations. It uses 32-bit floating point DSP for the variable crossover, dynamic limiting, and excursion limiting to create its powerful output and studio-quality sound. Its Active Integration means it delivers wireless and wired control of all setup, tuning, and monitoring functions, using free SL Room Control software for Mac®, Windows®, and iPad® and it works in concert with other PreSonus Active Integration products.

    Although it is designed to complement the full-range StudioLive AI speakers, the StudioLive 18sAI is flexible enough to work with other powered loudspeakers. An adjustable (0, 2, or 4 feet) alignment delay allows the subwoofer to be placed in different positions relative to a full-range speaker system and correctly combine with them. When used with a StudioLive 312AI, 315AI, or 328AI, the StudioLive 18sAI forms a true four-way system.

    Features:

  • 18-inch transducer with 1,000 watt, Class D amplifier
  • Active Integration 32-bit, 96 kHz DSP with variable crossover, dynamic limiting, and excursion limiting
  • Wireless networking with free SL Room Control software for Mac®, Windows®, and iPad® enables complete setup, tuning, and monitoring
  • Stereo line inputs (XLR-¼" combo) and switchable stereo/summed-mono line outputs (XLR)
  • Alignment delay (switchable: 0, 2, or 4 feet) enables subwoofer to be placed in different positions relative to a full-range speaker system
  • Integrated pole insert and interlocking stacking provisions
  • Active Integration 32-bit, 96 kHz DSP with more processing power than three rack speaker processors
  • Universal Switch mode power supply with power-factor correction
  • Comfortable, ergonomic handles
  • Ships with Ethernet connection for wired control; optional Dante card
  • Optional mountable Sub Dolly and pull-tested Sub Pole to mount a full-range system atop the 18sAI
