The all Group was formed in Hannover by H.-D. Hoffmann, H. Pabel, H. Enders and F. Hofmann in 1972. From the start it was divided into two divisions: all-electronic, concentrating on industrial production and investment and all-akustik, focusing on the import and marketing of entertainment electronics.
At the end of the 1970s´, all-akustik established its own brand of loudspeaker on the market: quadral. Within just a few years, quadral became synonymous with top-quality loudspeakers. TITAN, a giant loudspeaker conceived by Helmut Schaper, has always led the field; regularly updated over the decades, TITAN is regarded as the benchmark for all classes of speakers.
Its transmission line cabinet ensures a low, thudding, precise bass, the midrange unit developed specially for TITAN guarantees a soundstage of charming neutrality and transparency, and a ribbon tweeter provides flawless harmonics. Of course, the innovative strengths of TITAN were also passed on to the smaller models, to VULKAN, MONTAN, WOTAN, etc., names which still have a touch of magic about them.
Chief Developer Berndt Stark has been setting new trends at quadral since 1998. He promotes completely new technologies – such as those based on the pressure chamber reflex principle, not to mention quadral ALTIMA© membranes and RiCom tweeters – and favours cabinets that blend in as part of the furniture. His concepts have been rewarded with countless test successes both at home and abroad. Since then, our loudspeakers combine quadral’s traditional virtues, like neutrality of sound, balance and richness of detail, with easy and tasteful integration in the home, harmony with all types of music systems, also above-average clarity and party exuberance.
In 2000 quadral began to distribute Nakamichi and Sherwood in A/V and has completed its traditional loudspeaker-range with stylish surround-speaker-systems.
3 years later quadral launched a very new product, MAGIQUE. Each of the two satellites houses a 3-channel system which can provide a 6.1 surround sound with only each one cabinet at front and rear.
2004: “quadral goes design…” With the new SIGNO series quadral entered a new segment of the market. Ideally to be combined with Flat TV or LCD, SIGNO offers totally new selling opportunities. Our second highlight, the ARGENTUM series already walked off with awards. In the following year the biannual IFA brings a lot of novelties. We presented our wireless system ARGENTUM 02 WL which offers new possibilities of using speakers without cables. During Munich High End Show in 2006 quadral celebrated the 25th TITAN-anniversary and introduced the 7th generation of AURUM TITAN, VULKAN and MONTAN at Berlin IFA-show.
In 2007 the new AURUM generation has won a lot of test reports in Germany and other European countries. quadral launched the new PLATINUM ULTRA series developed for HiFi- and surround sound. Key-component is the exclusively designed RICOM ULTRA tweeter. The 2nd generation of shareholders, Jürgen Brinkmann and Edmond Semmelhaack, took over the quadral company from the founder generation in 2009 and started to renew the whole line-up.
During High-End show in Munich visitors could listen to the first samples of MONTAN VIII. From October on the first models of the 8th AURUM generation were shipped out to dealers.
CHROMIUM STYLE, with a new concept, was launched to the market. Slim and outstanding design combined with superb sound picture.
