The Grundig 3012 is a very special device called friendly "The bufferfly" because the loudspeakers position. The classification of Grundig devices is as follows:

Serie 1 xxx – Economic Class (ie.1060)
Serie 2 xxx – Economic - Medium Class (ie.2035)
Serie 3 xxx – Average Class (ie.3012)
Serie 4 xxx – Medium – High Class (ie.4035)
Serie 5 xxx - High Class (ie.5010)
Serie 6 xxx – Very High Class (ie.6099)

The Grundig 3012 belongs to the Medium Class but it has some features of the Upper Class.
Firstly, the final tube is a powerful EL12, normally used on Serie 5 devices.

The EL12 is a large pentode that delivers until 8W in A- Class.
The output transformer is a very large, almost like the power transformers in a normal radio, so it hardly goes into saturation.

Another important feature is the two elliptical loudspeakers.
Together, they can reproduce very low notes. Being smaller, they are faster and for this reason the bass is very limited, pleasant and modern.

Finally, the central tweeter and the symmetrical arrangement of the two broadband loudspeakers simulate a sound emitting point source. In this way, it is possible to get a remarkable “soundstage” effect and great depth of environment.

The cabinet of the radio is very beautiful and contains a surprise.
The clear frames that you can see on the sides are not painted, but they are inlaid.
All of these architectural choices do not belong to a Medium Class device, in fact Grundig 3012 is not a device of that class.

The tones control system is very efficient. Above the large tone control knobs there is a band that lights up gradually indicating the emphasis on the band on which it acts.
Interesting the high-tone control knob linked to two thin ropes. One of them is for the position indicator of the control itself, whereas the other changes the position of the ferrite in the MF transformers modifying the inclination of the transformer’s curve.
By doing so high tones were attenuated/accentuated even before getting to the BF stage. Tone control was usually put into effect with the potentiometer on the voltage amplifier stage

There are three speakers, but what matters most about this unit is their arrangement.
They are arranged to reproduce the sound as if it came from a point source, like in a single speaker.
The acoustic result is extremely enjoyable, and the rebuilding of the scene is realistic. You find the depth and the space.
The bass is very deep and fast, and the acute are balanced, thanks to the help of the central electrostatic tweeter.
I do not understand why this configuration was not re-proposed even in the most expensive models. Maybe just to keep costs down.
