Characteristics and sound properties

The Lisboa is a 2-way bass-reflex cabinet loudspeaker with drivers of Visaton .
The kit is delivered with the following drivers:

  • a Visaton B 100 full range driver
  • a Visaton PAW 25 woofer
    The crossover consists of:
  • a 2nd order high-pass filter (12 dB per octave slope) for the full range driver.
  • a 2nd order low-pass filter (12 dB per octave slope) for the woofer.
    The frequency response of this speaker is nearly linear.
    The decay spectrum is perfect.
    At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 1% above 200 Hz and doesn't exceed 1% at 95 dB at 1 m between 300 and 15000 Hz.
