Accuton Tigris Floorstanding Speakers as in K+T
Kit without cabinet, price per speaker
.
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.
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 . .
