WVL One is a two way compact speaker.

WVL One is available

WVL One is a loudspeaker with drivers of Wolf von Langa . Passive radiators provide deep bass.

The kit is delivered with the following drivers:
- a Wolf von Langa Beryllium (Made by Scan Speak) tweeter
- a Wolf von Langa AX-2676Be woofer

The loudspeaker has been developed by Dennis Frank, Daniel Gattig and Wolf von Langa.

The crossover consists of:
- a 3rd order high-pass filter (18 dB per octave slope) for the tweeter.
- a 3rd order low-pass filter (18 dB per octave slope) for the woofer.

The frequency response of this speaker is nearly linear.

The decay spectrum is nearly perfect.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,5% above 600 Hz and doesn't exceed 0,9% at 95 dB at 1 m between 300 and 15000 Hz.
