Tigris is a 2 way high-end floorstanding speaker. The kit provides an air motion tranformer (AMT) and two woofers of highest quality. The AMT is the very linear Air Motion Transformer Audaphon AMT-1i with very low distorsion. The woofers are Accuton C173-6-191E. This Accuton woofers you can find in a lot of high quality speakers in the five digit price range.
Tigris has been developed by Daniel Gattig and Dennis Frank.
The crossover consists of a 1st order high-pass filter (6 dB per octave slope) for the tweeter. An RCL circuit in parallel to the tweeter is smoothing the frequency response of the tweeter between 100 Hz and 2500 Hz. The woofers are connected to a 1st order low-pass filter (6 dB per octave slope). An RCL circuit in parallel to the woofers smoothing the membran resonances of the hard ceramic membran of the woofers.
Between 40 Hz and 21000 Hz, the frequency response of this loudspeaker is very linear on axis. 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 500 Hz and below 0.5% at 95 dB at 1 m .

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 DTAC 630 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
