The Stage 12 is a 2 way speaker with coaxial driver from Monacor. The kit is delivered with the Monacor SP-312CX.
The crossover consists of a 1st order high-pass filter (6 dB per octave slope) for the tweeter, a acceptor circuit is smoothing the resonance frequency of the tweeter. The woofer is connected to a 3rd order low pass filter (18 dB per octave slope).
The frequency response of this speaker is nearly linear. The decay spectrum is without extreme resonances. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are lower than 1% above 500 Hz and stays below 1% at 95 dB at 1 m (if f<5kHz).

The high-end kit is delivered complete 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 polypropylen (MKP) capacitors; for the tweeter even high quality Clarity-Cap CSA 630 V capacitors are employed.

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).
