The best of two worlds.

Each type of power amplifier has advantages and disadvantages. By employing different amplifier types for each driver, AIR12 loudspeakers use the respective strengths of Class D and Class A/B amplifiers to provide optimal response throughout the speaker’s frequency range. A 500W (continuous), Class D amplifier powers the 12-inch low-frequency driver, providing efficient, clean power for gut-shaking low end when you need it. A 200W (continuous), Class AB amplifier powers the 1.35-inch high-frequency driver, delivering a natural sounding, "AIR-y" high end. The combination can deliver up to 123 dB SPL of sweet, clear sound between 51 Hz and 20 kHz.

Versatile mounting for a variety of applications.

The AIR12’s molded plastic cabinet can be mounted in several ways, providing tremendous versatility. The multi-angle enclosure sports nonskid rubber feet on the bottom for upright front-of-house use and nonskid rubber feet on one side for stage monitor applications. Rig the speaker using M10 fly points or ground-stack it for portable applications. Mount it on a tripod or atop an AIR-series subwoofer using an optional sub pole. The integrated dual-position pole mount lets you aim the speaker level or at a 7.5˚ downward tilt. And the AIR12 is easy to transport, thanks to its top-mounted handle.

You’ll be floored.

If you place a loudspeaker against a hard surface such as a wall or floor, the low frequencies emitted from the rear of the enclosure propagate back into the room. This effect, called “half-space loading,” can increase the output of bass frequencies by as much as 6 dB, and it is an unavoidable issue with floor monitors. Most PA speakers in this class simply roll off excess low frequencies with a highpass filter—a half-baked compensation for half-space loading. In contrast, AIR-series full-range loudspeakers offer a Monitor preset that uses DSP to retune the speaker to both compensate for bass buildup and maintain a tight mid-bass response, while suppressing problematic frequencies to reduce feedback.

Flexible inputs.

AIR-series full-range loudspeakers offer a choice of inputs so you can use them with a variety of sources. You get two combo XLR mic/TRS line inputs, each with a Class A microphone preamplifier and independent gain control. A stereo 1/8” connection admits signals from smartphones, tablets, and other consumer audio devices. These signals can be combined with the AIR12’s internal mixer, and a balanced XLR Mix output lets you send pass the signals to other AIR-series loudspeakers.

A sweet-sounding solution.

With their “best of both worlds” power-amp configuration, carefully programmed DSP presets, versatile mounting options, flexible inputs with onboard mixing, and other professional features, PreSonus AIR-series loudspeakers are an excellent choice for both mobile and installed sound. You’ll love their easy transportability and their affordability. But the best thing about AIR-series loudspeakers is their clear, natural, “AIR-y” sound. Don’t just take our word for it, though.
