Subito-TL is a floorstanding loudspeaker with a full range driver.

Subito-TL is a transmission-line loudspeaker with drivers of Visaton .

The kit is delivered with a Visaton B 100 full range driver

The loudspeaker has been developed by Bernd Timmermanns.

The crossover consists of:

The frequency response of this speaker is nearly linear.

The decay spectrum is perfect.

At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 1% above 400 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 Visaton B 100 are of type polypropylen (MKP) Audaphon 400 V.

Impedance correction

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).


Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 6,30 excl. VAT: € 5.29 / $ 5.88

universal PCB

If you prefer to mount the crossover components on a 140 x 102 mm universal PCB instead on wood:
Universal PCB RA140, order no.. I-2765, price per unit:   EUR 3,70 excl. VAT: € 3.11 / $ 3.45
We recommend one board per kit (two boards for a speaker pair)
