Cobra-Horn RBT is huge speaker with Monacor fullrange loudspeaker SP-200X and magnetostat Monacor RBT-95SR. It has been developed by Bernd Timmermanns.
The crossover consists of a 2nd order low-pass filter (12 dB per octave slope) for the fullrange speaker and a 2rd order high-pass filter for the magnetostat
The frequency response of this loudspeaker is suitably flat.

The high-end kit comes with Mundorf MCAP capacitors. The 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 140 x 102 mm universal PCB instead on wood:

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