The ZEPHIROS is a very compact bi-amplified active nearfield monitor system with performances comparable to much larger systems. The ZEPHIROS is a high precision device with excellent efficiency and low distortion providing a very precise stereo imaging.

ZEPHIROS contains 2 x 5” neodymium long excursion and low distortion bass cone driver (LF), a 1” fabric dome tweeter (HF) loaded by an advanced waveguide, two class A/B power amplifiers producing 120W RMS (low) and 60W RMS (high) of output power each with very low THD and IM distortion values, a DSP (Digital Signal Processing) that gives an ultra-accurate crossover and amplitude response. An optimized FIR filter (Finite Impulse Response) ensures a quasi-perfect transient response and time alignment for an amazing soundstage.
