CT 285-SHT is a floorstanding speaker with full range driver and tweeter.
CT285 is developed by Holger Barske and Thomas Schmidt.
The cabinet contains two full range loudspeakers: the small Visaton FRS 5X and the bigger Visaton BG 20. With both there are three different variants:
The crossover consists of a third order high-pass filter (18 dB per octave slope) for the tweeter and a 2nd order low-pass filter for the woofer.
The frequency response of this speaker is linear. The decay spectrum is good. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are mostly not higher than 0.5% between 300 Hz and 10 000 Hz and doesn't exceed 1% at 95 dB at 1 m.

Kit without cabinet, price per speaker EUR 98,00 excl. VAT: € 82.35 / $ 96.35
Important: The costomised ring for the Visaton FRS 5X is not included in our kit.
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 MKP (polypropylen). In series to the tweeter a high quality Clarity-Cap capacitor of type ESA is delivered.

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 140 x 102 mm universal PCB instead on wood:
Universal PCB RA140, order no.. I-2765, price per unit: EUR 3,70 excl. VAT: € 3.11 / $ 3.64
We recommend one board per kit (two boards for a speaker pair)
