Ti Monitor is a 3 way monitor with mid and highrange adjustment. The kit provides the titan dome tweeter Visaton DSM 25 FFL and the titan dome midrange Visaton DSM 50 FFL. Viston W 250 S 4 Ohm is used for the bassrange .

Ti Monitor has been developed by Thomas Schmidt.

The crossover consists of a 3rd order high-pass filter (18 dB per octave slope) for the tweeter. A Visaton LC-57 is used for the sound adjustment. The midrange is connected to a 2nd order band-pass filter (12 dB per octave slope). A Visaton LC-57 is used for the sound adjustment of the midrange. The woofer is connected to a 2nd order low-pass filter (12 dB per octave slope).

Between 80 Hz and 20000 Hz, the frequency response of this loudspeaker is nearly linear on axis. The decay spectrum is nearly perfect. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are lower than 0.7 % above 300 Hz and below 1 % at 95 dB at 1 m .

Instead of Damping 30, we deliver the cheaper Bondum 800 with similar damping properties.

Kit with high-end crossover

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. All capacitors are of type polypropylen (MKP) and in series to the tweeter Clarity-Cap ESA 250 V are employed.

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 26,00 excl. VAT: € 21.85 / $ 26.87

universal PCBs

If you prefer to mount the crossover components on a universal PCB instead on wood
PCB 220x155 mm, order no. I-8805002, price per unit:   EUR 11,70 excl. VAT: € 9.83 / $ 12.09
We recommend one board per kit (two boards for a speaker pair)
