CT 310 is a two way compact speaker.
CT 310 is a bass-reflex cabinet loudspeaker with drivers of Visaton .
The kit is delivered with the following drivers:
- a Visaton FRS 5 X 8 Ohm full range driver
- a Visaton W 130 S 8 Ohm woofer
The loudspeaker has been developed by Holger Barske and Thomas Schmidt.
The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the full range driver.
- a 2nd order low-pass filter (12 dB per octave slope) for the woofer.
The frequency response of this speaker is nearly linear.
The decay spectrum (waterfall spectrum) shows a decelerated swing-out behaviour in the mid-range.
At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,6% above 300 Hz and doesn't exceed 0,8% at 95 dB at 1 m between 300 and 15000 Hz.

Kit without cabinet, price per speaker EUR 82,86 excl. VAT: € 69.63 / $ 80.00
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. The capacitors for the Visaton FRS 5 X 8 Ohm are of type polypropylen (MKP) Audaphon 400 V.
