StudioLive AI-series speakers incorporate Fulcrum Acoustics’ TQ Temporal Equalization algorithms that supposedly eliminate horn reflections and to correct linear time and amplitude anomalies in coaxial systems. 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.
Each full-range, powered, three-way loudspeaker relies on a custom-designed, CoActual 8-inch coaxial speaker with a 1.75-inch titanium compression driver to reproduce the mid and high frequencies. Triamplified, Class D power amplifiers in each model deliver a combined spec’d 2,000 watts of power.
The StudioLive 312AI includes a 12-inch ferrite speaker to handle low-frequency reproduction, while the 315AI employs a 15-inch woofer, and the StudioLive 328AI has dual 8-inch ferrite speakers.
Each full-range system has a combo XLR/TRS line input and an XLR microphone input with an XMAX Class A mic preamplifier and 12V phantom power, as well as an XLR audio throughput. The full-range speaker systems are pole-mountable and have side handles, interlocking stacking, and M10 fly points. All enclosures are of plywood construction.
Three operation modes allow the user to choose DSP presets for their application, such as MP3 playback, live performance or stage monitoring. Users can also create a custom preset using SL Room Control and store it onboard for use later.
The 1000-watt StudioLive 18sAI is a powered, 18-inch ferrite subwoofer designed to match the full-range StudioLive AI speakers. It includes stereo line inputs (XLR/¼-inch combo) and full-range stereo line outputs (XLR) with a switchable, low-cut crossover.
