Voice Horn is a two way compact speaker.
Voice Horn is a closed-cabinet loudspeaker with drivers/horns of Celestion, Visaton and Scan Speak.
The kit is delivered with the following drivers:
- a Celestion CDX1-1445 + Visaton HT 21 horn with driver
- a Scan Speak 22W-4534G00 woofer
The loudspeaker has been developed by Wolfgang Graßhoff.
The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the tweeter.
- 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 nearly perfect.
At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,5% above 300 Hz and doesn't exceed 0,8% at 95 dB at 1 m between 300 and 15000 Hz.

Kit without cabinet, price per speaker EUR 311,00 excl. VAT: € 261.34 / $ 261.34
The high-end kit is delivered with baked varnish air core coils on important parts of the crossover for minimizing microphonic effects. - The current flow through the coil creates a magnetic field which sets the reel of wire in motion. This motion induces a voltage in the coil which adds itself to the signal. The stiffer the reel of wire is, the less the signal will be altered. The capacitors for the Celestion CDX1-1445 + Visaton HT 21 are of type polypropylen (MKP) Clarity-Cap CSA 250 V.

If you want to use a valve amplifier with this speaker an impedance correction should be employed. In this case the component quality is less important; therefore, we offer only one kit (upon request higher quality components are available).
Price per impedance correction for one speaker, to be mounted on a small wooden board. EUR 9,00 excl. VAT: € 7.56 / $ 7.56
If you prefer to mount the crossover components on a 159 x 127 mm universal PCB instead on wood:
Universal PCB RA160, order no.. str-RA160, price per unit: EUR 5,90 excl. VAT: € 4.96 / $ 4.96
We recommend one board per kit (two boards for a speaker pair)
