PreSonus StudioLive 315AI 15" 3-Way Powered PA Speaker Studio monitors are designed to accurately reproduce music across a broad spectrum without signal loss or distortion but they can’t handle the SPL demands of a live show.

Conventional PA speakers can deliver plenty of volume, but except for very high-end systems, they can’t deliver the extremely clear, accurate sound one expects in a studio. As a result, an affordable PA speaker that delivers studio-monitor quality for live shows has remained an unfulfilled fantasy—until now.

This fantasy has, at last, become reality thanks to a partnership between PreSonus and Fulcrum Acoustic’s legendary engineer David Gunness (formerly of EAW and Electro-Voice). Rather than take the usual brute-force approach to PA-speaker design, the team designed a coaxial loudspeaker that would employ Fulcrum’s unique DSP-based approach.

The result is PreSonus StudioLive™ AI-series Active Integration Loudspeakers, the first affordable, active PA speaker systems that deliver studio-monitor accuracy on stage—exceptionally clear, coherent sound—while supplying the features and protection systems required to mix a live show that sounds great in a wide variety of venues, and with virtually any musical genre. These features include wireless and wired control of all setup, tuning, and monitoring functions, using an iPad® or laptop.

Coaxial designs offer the advantages of a single point source for a consistent acoustic centre and a symmetrical dispersion pattern. But designing coaxial systems without acoustic anomalies has been extremely expensive—until now.

Each StudioLive AI-series loudspeaker contains a DSP chip that enables the use of Fulcrum Acoustic’s TQ algorithms. The result is speakers that deliver the full benefits of coaxial design. Products that sense each other, interact and work together via wireless and wired communication, are seamlessly integrated with software, and run on CPUs far more powerful than competitors’ current audio products—PreSonus® has realised this dream with its new Active Integration technology.

The StudioLive 315AI features a 15-inch woofer and an 8-inch midrange driver and 1.75-inch titanium compression driver that are configured in a unique coaxial design and are driven by 2,000 watts of tri-amped, Class D amplification (1,000W for the woofer, 500W for the midrange driver, and 500W for the tweeter). This unit is the best choice if you are not using a subwoofer, though of course adding a StudioLive 18sAI subwoofer will give you even more bottom.

Using your PA speakers shouldn’t be a hassle—and with StudioLive AI-series PA speakers, it isn’t! PreSonus made the StudioLive 18sAI subwoofer easy to connect, easy to move, and easy to set up.
