PreSonus StudioLive 18sAI
18" Active Integration Subwoofer with 1000W Power Amplifier


PreSonus' StudioLive™ AI-series Active Integration Loudspeakers are the first active loudspeakers that deliver studio-monitor accuracy onstage and are equipped with complete wireless or wired remote control and monitoring using an iPad® or laptop.

All StudioLive AI-series speakers incorporate Fulcrum Acoustics' TQ™ Temporal Equalization algorithms.  TQ employs multiple, fully addressable Finite Impulse Response (FIR) filters to eliminate horn reflections and to correct linear time and amplitude anomalies.  Collaborating with Fulcrum Acoustics' co-founder, Dave Gunness, PreSonus software designers incorporated custom TQ algorithms with dynamics processing, FFT tools, and performance monitoring into the onboard DSP—quite possibly the most powerful suite of tools ever available in a loudspeaker system.  The result is a PA system with remarkably clear, coherent, studio-quality sound: Studio…Live!

Another key component of the StudioLive AI's distinctive design is its use of Active Integration technology.  Active Integration combines wireless and wired networking and communications with the aforementioned powerful DSP to create a unified working environment.

All StudioLive AI-series loudspeakers include a USB Wi-Fi module to connect to SL Room Control software over a wireless network.  SL Room Control is an impressive system-configuration application for Mac OS X®, Windows®, and iPad that provides both individual and grouped speaker control and includes a 31-band graphic EQ and an 8-band parametric EQ, muting, soloing, and level control, in addition to performance monitoring (over temperature, click detection, and excursions).  A network-setup wizard is also included to quickly connect each speaker to your wireless network via the optional Dante card (separate purchase).

The PreSonus StudioLive 18sAI is a powered, 18-inch, ferrite subwoofer designed to complement the full-range StudioLive AI speakers while still being flexible enough to work with other powered loudspeakers.  A 1,000W amplifier powers the subwoofer.  The StudioLive 18sAI offers stereo line inputs (XLR/1/4" combo) and full-range stereo line outputs (XLR) with a switchable, low-cut crossover.

Custom accessories for the AI-series speakers include a mountable Sub Dolly to make hauling the 18sAI subwoofer easy and a pull-tested Sub Pole to mount a full-range system atop the 18sAI. An M10 Kit, which contains four M10 eyebolts, lets you fly any full-range model in a permanent installation. A protective covers for the18sAI is also available (sold separately).
