About the Aerius
The Martin Logan Aerius is a hybrid electrostatic loudspeaker system that combines the clarity of electrostatic technology with the dynamic range of a traditional woofer. It features a 38-inch (96.5 cm) CLS (Curvilinear Line Source) electrostatic transducer for high frequencies and an 8-inch woofer with a sealed enclosure for low frequencies. The system is designed to provide an uncompromised listening experience with a frequency response of 40 Hz to 20 kHz ±3 dB. It is compatible with amplifiers rated for 4, 6, or 8 ohms and has a sensitivity of 89 dB/W/m (2.83V). The recommended amplifier power is between 20 and 400 watts per channel.
