Was ich damals auch nicht wußte, daß es ja insgesamt nur etwas weniger als 50 von den SS1 Systemen hier in Europa gegeben hatte. Die Seriennummern täuschen da ganz gewaltig. Nehmen Sie mal nur meine beiden letzten Ziffern der Seriennummern, also Panele Nr. 71 und Nr. 68.

Für Amerika und für die Masse der Amerikaner war das SS1 System mit deutlich über 3000.- Dollar fast so teuer wie eine große Blech-Karosse von Oldsmobile, denn die Verstärker und der Rest der Anlage kamen ja auch noch dazu. Die Amerikaner sind da weitaus preissensibler als wir hier in Deutschland. Ich vermute, daß es weltweit nur etwa 200 Infinity SS1 Systeme gegeben hatte. Von dem Nachfolger - der größeren und verbesserten Infinity SS1a - fanden nur 2 einsame Systeme den Weg nach Europa. Eines davon steht heute noch in Bonames.

The Servo-Statik I System represents a no-compromise music recreation standard which takes full advantage of advanced acoustic and electronic principles derived from computer science and aerospace technology. This unique sound system totally and without question eclipses any and all other music reproduction systems now commercially available, regardless of size or complexity.

The Servo-Statik I concept has completely eliminated the problems of all conventional electrostatic screens by using them in the range where they truly excel (midrange and treble) while using a dynamic speaker in the range where it excels (bass frequencies).

The dynamic speaker used for the bass frequencies can be no ordinary loudspeaker if it is to match the exceptionally low distortion and extended frequency characteristics of the electrostatic screens. For this formidable task, a new type of dynamic loudspeaker had to be designed -one which is actually incorporated in the feedback loop of the driving amplifier.
.

In addition, the bass system is placed in a decorative commode of moderate proportions which can be placed almost anywhere in the listening room due to the non-directional characteristics of bass frequencies of 100Hz and below. Thus, for the first time, it is possible to hear/feel the mighty 16Hz organ pedal note and on the same system experience the delicate bowing of strings and the spectacular transients of plucked strings of chamber music.

• Anmerkung : Das war natürlich (von uns damals geglaubter) Schwachsinn, weil physikalisch völliger Unsinn. Nach der glaubwürdigen Aussage von Herrn Brüggemann wurde auf keine Schallplatte dieser Welt eine 16Hz Frequenz drauf geschrieben, kein Tonbandgerät konnte 16Hz speichern und kein UKW Sender konnte 16Hz senden. Alleine die Obertöne hätte man hören können. Weiterhin ist die Wellenlänge von 20 Hz über 18 Meter, also in einem normalen Wohnraum gar nicht zu realisieren. - Und wir hatten das dennoch staunend geglaubt !

.

This is enough power at 35Hz to fill an enormous living room if not a small auditorium. The speaker is housed in a four cubic foot box of extremely sturdy construction and is filled with sound absorbing material. The amplifier which drives the bass system is a 110 watt RMS DC amplifier capable of peak powers in excess of 200 watts. It utilizes all-silicon transistors and computer grade components including an integrated circuit operational amplifier at the front end and advanced complementary symmetry circuitry throughout. The amplifier also has contained within it an electronic crossover which correctly feeds the bass system and screens with the proper frequency spectrum.

The peerless sound quality of the electrostatic transducer arises principally because of three factors:

• 1) the extremely low mass of the moving system;
• 2) the driving force is distributed uniformly over the moving diaphragm area, and;
• 3) constant energy output as a function of frequency.

.

The diaphragm of an electrostatic reproducer is of low mass because it is extremely thin, approximately .0005" in thickness. The low mass gives the screen excellent transient response since the diaphragm can be accelerated very rapidly (due to the small inertial mass) while the resistance of the air load damps out any overshoot.

Moreover, the low mass of the tweeter diaphragm (.00025" in thickness) can give flat frequency response up to and beyond 30KHz. High frequency rolloff occurs when the mass of the diaphragm is equal to the mass reactance of the air load in front of the diaphragm. This occurs at about 30KHz in the Servo-Statik I System, after which the response drops off at 6db per octave.

The fact that the electrostatic screen utilizes a uniform electric driving force over its entire radiating area serves to virtually eliminate what is called "cone-breakup" (one of the principal factors which produce distortion in conventional loudspeakers, caused by the cone being driven only at its center). In most instances, distortion in screens never exceeds 0.5%.

The Infinity systems' electrostatic speakers differ in design from most conventional units.
.

• First, they are designed for exceptionally high-power handling capacity and therefore can handle most amplifiers fed into them (there are no fuses in series with the speaker line).
• Second, the grids on either side of the diaphragm are highly conductive rather than highly resistive; thereby giving constant power output at all frequencies and exceptional articulation.

.

Finally, the dispersion characteristics of the screens are vastly different than most electrostatics. The Servo-Statik I System has eliminated the dispersion problems of conventional units by utilizing narrow strip tweeters and compound angled midrange modules which results in flat frequency response on or off axis. Additionally, the screens radiate 50% of their energy in the rear direction, adding the correct amount of reflected sound in the room and resulting in concert hall realism and smoothness.
