Hans German Loudspeaker

The developments of the Austrian "acoustics researcher" Hans Deutsch were offered over time by different companies and under different brands.

After some single pieces, in the sixties, Hans Deutsch started to have his own developments mass-produced for his own company in the seventies.
After the takeover of the Salzburg company by the Offenbach-based JWS, Hans Deutsch limited himself to the development of loudspeaker boxes and looked for a partner for the production and marketing in the Munich-based Light&Sound. For this purpose, the Munich-based Atlantic Lautsprecher GmbH sales company was founded.
In 1982, the previous sales manager of Atlantic founded his own company, ATL Lautsprecher GmbH Vertriebsgesellschaft, which from now on should realize and market the developments of Hans Deutsch.
The separation from ATL took place in 1989. From now on, the creations developed at HD-Akustikforschung were offered by Hans Deutsch Lautsprecher GmbH in Surheim.
As the last partner in the Federal Republic, since the early nineties, SMG acts as licensee of Hans Deutsch and continues to offer for sale a part of the series developed in the eighties. At the same time, Hans Deutsch began to design entirely new boxes, which were initially built and marketed by the company Bösendorfer Klavierfabrik GmbH. When the manufacturer was bought out by Yamaha, the Joseph Brodman Group took over the developer's loudspeaker boxes.


Design principles[edit]

Hans Deutsch loudspeaker cabinets are exceptional reproduction instruments, distinguished by the use of a series of inventions by the "acoustic researcher" which, in this form, have not been used by any other developer.
These inventions, most of them patented, have always been the cause of controversy. However, the survival of his ideas, as well as countless successful test reports and positive reactions of, partly professional, users, prove the success of his constructions, through which, as his office describes it, "'.... exceptionally natural, spatial and clear sound reproduction is achieved.

These special sound characteristics of Hans Deutsch loudspeakers are based primarily on the following design principles, which have been applied in different ways in the various generations of loudspeaker boxes developed by him:

1. the horn resonator[edit]

2. the acoustic-active crossover[edit]

3. The B&S system[edit]

4. the spatial reproduction[edit]

At the German Patenamt you can download this document DE000008123890U1_all_pages.pdf, in which the spatial reproduction by the lateral radiation of the midrange driver is explained. The principle of the lateral radiating midrange driver was especially used in the Atlantic Series 001-005.

5. the FT system[edit]

6. the Acoustic Sound Boards[edit]

Loudspeakers by Hans Deutsch[edit]

Original models[edit]

The original series models were made for Hans Deutsch GmbH & Co. KG in Salzburg and were offered in the Federal Republic by the J.W. Audio representations. Soon the distributor Josef Wetz took a share in the developer's company and the now High Fidelity Lautsprecherbau Hans Deutsch GmbH & Co. KG was exclusively represented by the now JWS Audio System (Waldstr. 122, 6050 Offenbach).
After the final takeover of the Salbzug company by JWS, Hans Deutsch began a collaboration with Munich-based Atlantic, while JWS continued to offer the Poseidon models on its own.

JWS models[edit]

After the separation of Hans Deutsch from the German distribution and new owner of his former Salzburg company, the JWS offered models, respectively the further developments of the models of the Salzburg creations of Hans Deutsch, until the eighties

Atlantic series[edit]

Around 1976, Hans Deutsch began collaborating with Munich-based Light & Sound, which led to the founding of Atlantic, a company that took over the manufacture and distribution of speakers designed by Hans Deutsch.
After a few successful years, the brand was changed to ATL on the advice of an advertising agency, and the company was also initially renamed ATL Atlantic Lautsprecher GmbH Vertriebsgesellschaft in 1982. At the same time, the largest and most expensive model, the Skyline, disappeared from the range. Admittedly, a successor for the top model was already in development.
The company Atlantic ended its activities in 1982, which also marked the end of the speaker series.

1st generation from 1976-81[edit]

2nd generation from 1982[edit]

HD series[edit]

With the introduction of the new HD series, Hans Deutsch also responded to the now changed, more straightforward style in box design. In particular the horn resonator became now also the determining formative characteristic. Simultaneously with the introduction of the HD-series a new brand ATL was invented, which led to the foundation of the ATL Lautsprecher GmbH Vertriebsgesellschaft in 1982, which was to offer the HD-series until the beginning of 1989.
In succession to ATL, as manufacturer and distributor of its speakers, Hans Deutsch Lautsprecher GmbH, in Surheim, was formed in the spring of 1989, under the management of the developer's daughter, to continue the HD series. With the dissolution of the Surheim company, the HD series also ended; at least Sound Magic GmbH continues to offer two revised models.

light-style series[edit]

To complement the basic HD series, Hans Deutsch Lautsprecher GmbH in Surheim, registered in May 1989, began to introduce new models from the HD acoustic research. With the dissolution of the Surheim company, the Light Style series ended; at least Sound Magic GmbH continues to offer three revised models.

M-series[edit]

As a further development of the previous top model Dell'Arte, the introduction of the new M series already started at ATL, with the M6 still as Antares. The M models remained available until the dissolution of Hans Deutsch Lautsprecher GmbH, which was incorporated in May 1989.

FT series[edit]

The Fundamental Töner are a series of adjustable subwoofer boxes, each matched to a specific model of the M series, and which in combination are supposed to improve their sound even more noticeably.
The FT models will remain available until the dissolution of Hans Deutsch Lautsprecher GmbH.

Others[edit]

These loudspeaker boxes are conventionally designed entry-level models made by Hans Deutsch Lautsprecher GmbH in Surheim.


Sound Magic distribution[edit]

After the termination of Hans Deutsch Lautsprecher GmbH, SMG took over some selected models under license. The distribution was discontinued at the end of 2020.
