Description

Grundig HiFi Box 706 Audioprisma speakers. Classic Vintage. Fully revitalized.

 

Grundig was established in 1945. After the World War II, the Allies watchfully controlled the production of radio receivers in Germany. Max Grundig saw a niche and created a “Heinzelmann” i.e. a Grundig radio without tubes, which officially was not categorized as a radio and thus was not controlled. The product was so successful that the company was able to quickly build its own factory. In the early 50s, Grundig created its own model of a tape recorder and a TV set specially for the premiere of the first German TV channel. Already at that time, the company was the largest manufacturer of radio receivers in Europe.

In 1957, Grundig acquired a majority stake in typewriter manufacturers: Triumph and Adler, which enabled the creation of the biggest tape recorder factory in the world. The company introduced modular systems with separate components (radio, stereo amplifiers, vinyl record players, tape recorders, separate speakers, and even 3D audio devices) making it possible for customers to create their own hi-fi sets, according to their individual needs and interiors. In 1967 Grundig launched a compact cassette recorder, soon followed by a car cassette recorder. In 1969, it produced Europe’s first hi-fi amplifier with a built-in equalizer, which became a bestseller. Twenty years later, at the age of 81, the founder Dr. Max G. Grundig died, and in 1993, Philips, which had been buying Grundig’s stock since the 70s, took complete control of it.
At the turn of the 20th and 21st centuries, Grundig quickly recognized the enormous potential of mp3 technology and began to develop it, thus becoming one of the market leaders. Since 2007, Grundig Intermedia GmbH has been part of Arçelik A.Ş. and a producer of a variety of electronic devices, ranging from MP3 players, through TV sets to household appliances.

The 70s are unanimously regarded as a golden age for products from the Grundig family. The designs created during this time, such as the HiFi Box 706 loudspeakers, are characterized by an exceptionally high level of quality. The speakers belong to the unique Audioprisma series equipped with a distinctive acoustic lens in the upper front, placed in front of the tweeter. Grundig promoted this model under the slogan “high performance in the smallest enclosure” claiming that the listener “experiencing the amazing sound will forget everything that came before”. The idea was to achieve a fascinating sound effect resembling perfect, surrounding radiation. The speakers themselves remain, so to speak, ‘acoustically invisible’.

The sound is extremely natural and coherent. It is based on a soft, descending bass, balanced midrange and delicate treble. The rich soundstage displays all details and nuances.

The enclosures have been completely revitalized. Walnut wood adds incredible charm to the speakers. High quality finishing screws. The capacitors in the crossover have been replaced. New terminals. The fronts of the speakers and selected elements have been painted using the automotive wet painting technique. The wood finish is Chinese oil produced from natural oils, as well as turpentine-based beeswax. The wood is very pleasant to the touch. Grilles made of high quality acoustic fabric.

Included are two speaker cables with a cross section of 2 × 2.5mm and length of 2x5m.
The set is 100% functional, the speakers are in perfect condition.
