CT 282 is a low-cost kit. CT 282 has been developed by Thomas Schmidt.

CT 282 is a FAST system (Fullrange and subwoofer technology) with Mivoc fullrange speaker FR358 and Mivoc subwoofer SWM 68.

The crossover consists of a first order high-pass filter (6 dB per octave slope) for the fullrange loudspeaker. In addition two serial wave traps are used to smooth the frequency response. A second order low-pass filter (6 dB per octave slope) is used for the woofer.

Our kit consists of

  • Tweeter Mivoc FR 358 N
  • Woofer Mivoc SWM 68
  • PE sealing tape, 5x2 mm
  • Damping Sonofil 100 x 35 cm for 20 litres
