12-inch Three-way Coverage with the CoActual Difference

The StudioLive® 312AI delivers 3-way coverage, with a 12-inch low-frequency driver and our proprietary 8-inch, CoActual® coaxial speaker for mid- and high-frequency reproduction. These transducers are driven by a hefty 2,000W RMS of triamplified, Class D power, all housed in a compact enclosure. The 312AI is time- and phase-aligned to form a true 4-way system when paired with the StudioLive 18sAI subwoofer. And it’s fully controllable with SL Room Control for iPad®, Mac®, and Windows®.

The proprietary CoActual 8-inch, horn-loaded coaxial speaker offers a consistent acoustic center—a single point source that offers unique advantages, thanks to the driver’s symmetrical response. The net result is exceptional 3D imaging and a natural listening experience that reveals the subtlest details.

A Unique Design with Studio Monitor Fidelity.

The StudioLive 312AI is equipped for wireless and wired communications over an Ethernet or Wi-Fi LAN for monitoring and control. Better yet, add the SL-Dante-SPK option card to create a Dante network and ditch your analog cables in favor of lightweight CAT5 cables.
