White Ebony is a 3 Way floorstanding speaker with drivers of high quality from Scan-Speak. The tweeter is the Scan-Speak D3004/66000. In the White Ebony kit the Scan-Speak 12MU/8731T00 is used as mids speaker.The woofers are two Scan-Speak 22W/8851T00. White Ebony has been developed by Dr. Werner Hartmann and is shown in journal Hobby HiFi as readers project .

The crossover consists of a 3rd order high-pass filter (18 dB per octave slope) for the tweeter, a bandpass filter (12 dB high - and 12 dB low-pass) for the mids. The two woofers are connected to a 3rd order low-pass filter each.

Between 40 Hz and 20000 Hz, the frequency response of this loudspeaker is linear on axis.
