The Adhara is an high-end 2 way floorstanding speaker with high quality chassis. The kit is delivered with air motion transformer Audaphon AMT-1i and
with Wavecor WF182CU13 of high quality as midwoofer for the bass range.
Adhara has been developed by Daniel Gattig and Dennis Frank.
The crossover consists of a 3rd order high-pass filter (18 dB per octave slope) for the tweeter,
a RCL circuit in parallel is smoothing the frequency response between 3 kHz and 8 kHz and a parallel RCL circuit in series to the loudspeaker
is smoothing the frequency response between 15 kHz and 25 kHz. The woofers are connected to a 3rd order low pass filter (18 dB per octave slope).
A RCL circuit in parallel to the woofer is smoothing the frequency response between 600 Hz and 1,5 kHz.
The frequency response of this speaker is outstanding linear. The decay spectrum is nearly perfect. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are lower than 0.4% above 300 Hz and doesn't exceed 1% at 95 dB at 1 m .

The high-end kit is delivered with baked varnish air core coils 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.

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).
If you prefer to mount the crossover components on a universal PCB instead on wood

We recommend two boards per kit (4 boards per speaker pair)
