The extreme care paid to the design of the Mylar – Titanium alloy transducer enabled us to combine rigidity, lightness and high damping properties to preserve the dynamics of the audio signal and to provide remarkably neutral sound without any distortion. The highly accurate reproduction of bass frequencies will reveal
the smallest defects in the mix, while avoiding acoustic constraints of the workspace. Spirit Professional offers excellent acoustic insulation to address the constraints of the often noisy environments specific to Broadcasting and Home Studios.
