CT 332 is a two way floorstanding speaker.

CT 332 is a dipole loudspeaker with drivers of Dynavox .

The kit is delivered with the following drivers:
- a Dynavox LY401F full range driver
- eight woofers Dynavox DY166-9A, 4 Ohm

The loudspeaker has been developed by Olaf Schauer.

The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the full range driver.
- a first order low-pass filter (6 dB per octave slope) for the woofer.

The frequency response of this speaker is nearly linear.

The decay spectrum is nearly perfect.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,5% above 300 Hz and doesn't exceed 1% at 95 dB at 1 m between 300 and 15000 Hz.

Kit with high-end crossover

The high-end kit is delivered with 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. The capacitors for the Dynavox LY401F are of type polypropylen (MKP) Clarity-Cap PWA 400 V.
