PreSonus StudioLive 18sAI

18-inch Active Integration subwoofer
MFR# StudioLive 18sAI

Product Description

PreSonus StudioLive 18sAI Active Integration subwoofers deliver studio-monitor accuracy onstage with unprecedented onboard processing and networking features. PreSonus® Active Integration technology enables wireless and wired networking control for setup, tuning, and monitoring functions, using an iPad®, a Mac or Windows laptop, or both. Powerful and musical, the StudioLive 18sAI naturally extends low-frequencies with a fast and accurate transient response and is a perfect mate for StudioLive 312AI, 315AI, and 328AI full-range loudspeakers, making it an ideal choice for installations and mobile applications where fidelity matters.

Tight, clean, natural bass

Designed to complement full-range systems, without overshadowing them, the StudioLive™ 18sAI active subwoofer naturally extends the reach of your full-range systems’ low end to deliver studio monitor accuracy throughout its range. Driven by 1,000W RMS of Class D amplification, the 18sAI’s 18-inch ferrite speaker delivers exceptional low-end performance down to 35 Hz. The net result is a musical approach to sub-bass frequency reproduction that affords a natural listening experience on a large scale.

A four-way PA that works as one

Although the StudioLive 18sAI is flexible enough to work great with other powered loudspeakers, when used with a StudioLive 312AI, 315AI, or 328AI, the StudioLive 18sAI forms a true four-way system. For applications that require a more linear (“flat”) frequency response between the subwoofer and full-range speaker, engage the highpass filter on the full-range StudioLive AI-series loudspeaker to readjust the phase and time-alignment, keeping the full-range system in phase with the 18sAI subwoofer. Need a little more bump? Leave the highpass filter off and enjoy the perfectly phase- and time-aligned overlap at 100 Hz between your full-range system and your subwoofer.

​Networkable with Wi-Fi, Ethernet, or Dante

The StudioLive 318sAI comes equipped for wireless and wired communications over an Ethernet or Wi-Fi local area network for monitoring and control over custom tuning settings. Better yet, add the SL-Dante-SPK option card to create a Dante network and ditch your analog cables in favor of lightweight CAT5e or CAT6 cables.\

You’re in control—here, there, and everywhere

The StudioLive 18sAI subwoofer features a robust onboard loudspeaker processor that can be accessed and controlled over a standard LAN network. PreSonus’ SL Room Control software makes customizing your speaker system as simple as connecting an Ethernet cable to a wireless router. Creating a cardioid subwoofer array is as easy a pressing two buttons, thanks to onboard polarity reverse and three alignment-delay presets. ​

Flexible connections and mounting capabilities

The rear of the StudioLive 18sAI reveals stereo line inputs (XLR/¼-inch combo) and full-range, switchable stereo/summed-mono line outputs (XLR). An optional, pull-tested Sub Pole lets you safely and securely mount a StudioLive AI full-range system atop the 18sAI. An optional, mountable, heavy duty Sub Dolly lets you roll your StudioLive 18sAI in and out with minimal stress, and the lightweight plywood enclosure includes ergonomic side handles.

Clear, accurate, powerful—and available now

Whether out on tour or installed in a venue, the StudioLive 18sAI subwoofer mates perfectly with StudioLive AI full-range loudspeakers to deliver studio-monitor accuracy at incredibly high SPLs. With extensive software control and wired and wireless networking, it offers advance capabilities that go well beyond conventional point-source loudspeakers, yet it’s easy to set up and use.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
