FR10 TL is a slim floorstanding speaker that employs a Visaton FR10 8 Ohm woofer and a Visaton DTW 72 8 Ohm tweeter.
FR10 TL has been developed by Bernd Timmermanns.
Its transmission line cabinet ensures a punchy bass and precise bass.
The crossover consists of a 2nd order high-pass filter (12 dB per octave slope) for the tweeter. A RCL curcuit in parallel to the tweeter is smoothing the frequency response of the tweeter. The woofer is connected to a 3rd order low-pass filter (18 dB per octave slope).
Between 60 Hz and 20 kHz, the frequency response of this loudspeaker is nearly linear on axis. The decay spectrum is without fault. At low volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 1% above 300 Hz.

The high-end kit comes with MKP capacitors for the tweeter. All inductances are baked varnished 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.

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 159 x 127 mm universal PCB instead on wood:

We recommend one board per kit (two boards for a speaker pair)
