1968

First patent application

Josef Manger returned from a 3 year stay in Australia to take over the family business at home in Germany. He decided to start importing PA systems from famous US brands like Marshall, Fender, Klipsch for the classic radio and TV shop.
While mainly selling these products to bands and musicians he got introduced to the sound of instruments and its reproduction through audio systems. He soon realized that the reproduction of music through state-of-the-art technology was not the same experience that you could have during a live concert.
Wondering why, he began his meticulous research by measuring the frequency response of various speakers. When compared it became obvious that they are technically all quite similar, even though the sound is quite different. Josef W. Manger started to drill down on his idea to investigate the time behaviour and step response. He quickly noticed huge differences between the tested speakers.
In his relentless pursuit for better solutions, Josef W. Manger started to look for alternative setups for electroacoustics and materials. The easy part was to figure out that conventional drivers work like mass-spring systems, swinging after excitation. This problem led him to his first solution and patent: a woofer with a free air resonance of 7 Hz.

Push-pull moving coil loudspeaker having electromagnetic centering means

An electrodynamic acoustic transducer such as a loudspeaker or a microphone in which the datum or center position of the diaphragm is determined by two voice coils. The coils are fixed to one another and to the diaphragm and cut magnetic fields. Datum currents are provided for the coils and the coilds are of non-uniform density of winding and/or the magnetic fields are nun-uniform. The coils and the datum currents are arranged to proved the balanced forces on the coils only when the diaphragm is in the datum position.

 

1972

2nd patent - Membrane

After being granted his first patent, Josf W. Manger soon realized that the main limit to natural audio reproduction cannot be found in the slow motion movements of the low end, but in the fast movements of the tweeter. His reasearch took him to a paper from the inventors of the piston driver: Rice and Kellogg. In their paper, the two described the idea of a mechanical resistor being the prime principle for sound reproduction. Since “no” has never been an option for the entrepreneur Josef W Manger, his vision was now supported by a clear aim which led him to his second patent:

Abstract

An electro-acoustic transducer has a diaphragm with a moving coil. The diaphragm consists of a flat textile carrier impregnated with a highly attenuating filling material and is highly elastic in its plane but inelastic in bending.

First publication

The German special interest magazine "Funkschau" features the fully functional Manger Sound Transducer W02 along with detailled theoretical background information.

1974

47th AES Convention, Copenhagen

First technical presentation of the Manger® sound transducer during the 47th AES (Audio Engineering Society) Convention in Copenhagen, Denmark

"AN IMPULSEXACT TRANSDUCER WITH ELECTRODYNAMIC DRIVING UNIT"

In this paper the principals of a new transducer system are given. This new idea is governed by the rules, that ther must be no time delaying energy storaging during the transformation of the electrical form of energy into the mechanical form of energy as fa as the audio range is concerned. How this is achieved is described in details and measured results are represented and compared with conventional loudspeakers.

1975

First international presentation

Presentation at the IEE (The Institution of Electrical Engineers) in London by Josef W. Manger

1976

W02 - the next Generation

The unique and remarkable time behaviour of the bending wave principle is demonstrated by the W02.

1978

Continued development & international patents

Further developments on the diaphragm: Three layer sandwich diaphragm - This leads to considerable improvements of the bending wave behaviour and already at this time a frequency range up to 30 kHz. The Manger Sound Transducer W03 reached a considerable sensitivity of appr. 84 dB/1 W/1 m - Further worldwide patent applications.

S05 further improved

S05 - the flying disc with its extraordinary look creates a lot of attention

and from the beginning it was one of the quality criteria of the Manger sound system: " You can listen at low levels without missing nothing."

First full active monitor system

Presentation of the Manger Sound System MSS, a fully active floorstanding studio monitor at the 15th Tonmeistertagung (Conference of Sound Engineers) in Munich. The talk "Transient behaviour of microphones and loudspeakers" by Josef W. Manger, was widely discussed.

The Manger Sound System MSS is the ancestor of the Zeroboxes and was soon used at many studios and institutes in Germany, Austria and Switzerland as a reference monitor system.

Introducing a new line: the Zerobox

Development of the Zeroboxes - Zerobox 103, Zerobox 107 and Zerobox 109

Zerobox means: "There is no cabinet footprint, by the pressure change. Side-mounted drivers support pneumatically the front driver and create an infinite baffle."


 

1991

Introducing even stronger Neodymium magnets

The induction in the 0,95 mm small air gap reaches 1,3 Tesla through the new Neodymium magnet. This new rare earth magnet material finally pushes the sensititvity up to 91 dB (1 W/ 1m).

Neodymium

Another chief use of neodymium is as the free pure element. It is used as a component in the alloys used to make high-strength neodymium magnets—powerful permanent magnets. These magnets are widely used in such products as microphones, professional loudspeakers, in-ear headphones, and computer hard disks, where low magnet mass or volume, or strong magnetic fields are required. Larger neodymium magnets are used in high power versus weight electric motors (for example in hybrid cars) and generators (for example aircraft and wind turbine electric generators).

Manger hits the clubs

Never say no! This was our conviction for the very first sound reinforcement project for a club in Berlin. With the precision of the Manger sound transducer we were aware that there happens no hearing threshold shift and ringing on high sound pressure levels. So with custom-made speakers we equipped the first club in Berlin.

Manger technology in demand for public locations

Manger planned and installed a complete sound reinforcement system for a market and event hall in Nuremberg-Fuerth.

i1 - the first in-wall speaker

i1 - in-wall speaker
An innovative solution of an in-wall cabinet and
the Manger Sound Transducer. As it is predicted by its
bandwidth and the low depth for in-wall. In 2015 we
decided to start with a design of an in-wall speaker.

The in-wall cabinet is a dedcated sandwich
construction, which combines materials for
a high sound reduction.
A clever mounting mechanism let adjust the depth
of the Manger driver with our without cover.




 

The explosion graphiques below visualize all the
details of this innovative cabinet construction.
