Orchestra Monitor 4 is a two way compact speaker.
Orchestra Monitor 4 is a bass-reflex cabinet loudspeaker with drivers of Eton .
There is also a bass extension Orchestra TT 8.
The kit is delivered with the following drivers:
- a Eton 29 HD 2 tweeter
- a Eton 4-612/C8/25RP midrange / bass driver
The loudspeaker 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 3rd order low-pass filter (18 dB per octave slope) for the woofer.
The frequency response of this speaker is nearly linear.
The decay spectrum is nearly perfect.
At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,6% above 300 Hz and doesn't exceed 1,5% at 95 dB at 1 m between 300 and 15000 Hz.

Kit without cabinet, price per speaker EUR 317,00 excl. VAT: € 266.39 / $ 298.35
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 tweeter are of type polypropylen (MKP) Clarity-Cap CSA 630 V.

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 universal PCB instead on wood

We recommend one board per kit (2 boards per speaker pair)
