Hotan is a 2 way high-end pa speaker with hifi sound. The very linear driver-horn combination Faital Pro HF 200 and P-Audio PH-2380 is employed as tweeter. Two woofers Celestion FTR15-3070C are for the bass. Each of the loudspeakers feature two 15 inch woofers Celestion FTR15-3070C.
Hotan 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. Two RCL circuits in parallel and one in series to the tweeter are smoothing the frequency response. The woofers are connected to a 1st order low-pass filter (6 dB per octave slope). An RCL circuit in parallel to the woofer is smoothing the frequency response. The Midwoofer is connected to a 2nd order low pass filter (12 dB per octave slope).
Between 50 Hz and 15000 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 0.5% above 200 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 ESA 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 PCB 220x155 mm, order no. I-8805002, price per unit: EUR 11,80 excl. VAT: € 9.92 / $ 10.21 We recommend two boards per kit (four boards for a speaker pair)
