CT 305 is a floorstanding loudspeaker with a full range driver.
CT 305 is a horn loudspeaker with drivers of Visaton .
The kit is delivered with a Visaton B 100 full range driver
The loudspeaker has been developed by Thomas Schmidt.
The crossover consists of one RC curcuit in series to the loudspeaker.
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 0.7% above 400 Hz and doesn't exceed 1.6% at 95 dB at 1 m between 300 and 15000 Hz.

Kit without cabinet, price per speaker EUR 109,00 excl. VAT: € 91.60 / $ 108.08
The high-end kit is delivered with a baked varnish air core coil 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 capacitor for the Visaton B 100 is of type polypropylen (MKP) Clarity-Cap ESA 630 V.

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.. str-RA140, price per unit: EUR 4,20 excl. VAT: € 3.53 / $ 4.16
We recommend one board per kit (two boards for a speaker pair)
