PreSonus 18sAI overview

  • 1Description

The PreSonus 18sAI 1,000W Powered 18" Subwoofer with Active Integration features a ferrite driver and a 32-bit/96 kHz DSP chip. Because of all the onboard technology, the 18sAI is able to deliver wired and wireless control of all setup, tuning, and monitoring functions using the free SL Room Control software for Mac, Windows, and iPad.

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

The 18sAI subwoofer has a stereo pair of XLR/TRS combo line inputs and a stereo pair of XLR full-range line outputs. The line outputs can also be switched to sum mono. The lightweight plywood enclosure includes ergonomic side handles, an integrated pole insert and interlocking stacking provisions.

Active Integration
PreSonus Active Integration employs an OMAP 5 multi-core ARM 2GHz Cortex-A processor. This 32-bit/96 kHz DSP system includes an operating system, wireless and 100Mb Ethernet communications, USB 2.0 and 532 MHz LPDDR2 SD RAM.

The included USB Wi-Fi LAN adapter enables wireless networking. Wired communications are provided via an installed option card with an Ethercon port that connects to your Ethernet-based LAN network.
Onboard TQ Temporal Equalization by Fulcrum Acoustics
The 18sAI's DSP chip also powers Fulcrum Acoustic's TQ algorithms. The TQ algorithms use fully addressable Finite Impulse Response (FIR) filters to eliminate horn reflections and to correct linear time and amplitude anomalies. Loudspeakers tuned with TQ provide a crisper stereo image, greater soundstage depth, more separation between the elements of a complex mix, increased resistance to feedback, more seamless transitions between distributed loudspeakers, and a less fatiguing listening experience.
SL Room Control Software
The master control center resides in SL Room Control, an easy-to-use system configuration app for Mac, Windows, and iPad that offers individual or group control of StudioLive AI-series speakers on the network. A Network Setup Wizard automatically detects each speaker and allows you to quickly connect to your wired or wireless network. Once connected, you can create, edit, save, and recall speaker-setup parameters. Additionally, Operation Modes allow you to choose between optimized settings for different applications.
