Each type of power amplifier has advantages and disadvantages. By employing different amplifier types for each driver, AIR15 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 15-inch low-frequency driver, providing efficient, clean power for gut-shaking low end when you need it. A 200W (continuous), Class A/B amplifier powers the 1.35-inch high-frequency driver, delivering a natural sounding, “AIR-y” high end.

The combination can deliver up to 132 dB SPL of sweet, clear sound between 40 Hz and 20 kHz.
