CT 284 is a dipole speaker with drivers from Visaton.
CT 284 is a 2 Way F.A.S.T (Fullrange and subwoofer technology) floorstanding speaker.
It is home to a fullrange loudspeaker Visaton BG 13 P and two woofer Visaton W250, 8 Ohm.
CT284 is developed by Holger Barske and Thomas Schmidt .
The crossover consists of a second order high-pass filter (12 dB per octave slope) for the tweeter. A serial RCL is smoothing the frequency response in the midrange. The woofers are connected to a 2nd order low-pass filter.

The high-end kit is delivered with baked varnish air 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 foil capacitors.

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
