The Avior is an high-end 2 way floorstanding speaker with high quality chassis. The kit is delivered with Audaphon Neo Pro 5i ribbon tweeter and two of Wavecor WF182CU13 of high quality as midwoofer for the bass range.

Avior has been developed by Dennis Frank and Daniel Gattig.

The crossover consists of a 3rd order high-pass filter (18 dB per octave slope) for the tweeter, a parallel RCL smoothing the frequency response between 5 kHz and 20 kHz. The woofers are connected to a 2nd order low pass filter (12 dB per octave slope). Two parallel RCL soothing the frequency response at 1,2 kHz and 4,5 kHz.

The frequency response of this speaker a very linear. The decay spectrum is nearly perfect. At low volume, i.e. 85 dB at 1 m, the nonlinear distortion is lower than 0.4% above 300 Hz and doesn't exceed 0,5% at 95 dB at 1 m .

Kit with high-end crossover

The high-end kit is delivered with copper foil and 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. All capacitors are of type polypropylen (MKP) and in series to the tweeter Clarity-Cap ESA 250 V are employed.

Impedance correction

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 23,30 excl. VAT: € 19.58 / $ 17.48

universal PCBs

If you prefer to mount the crossover components on a universal PCB instead on wood
PCB 220x155 mm, order no. I-8805002, price per unit:   EUR 11,70 excl. VAT: € 9.83 / $ 8.78
We recommend two boards per kit (four boards for a speaker pair)
