Quadral

Philosophy Are all loudspeakers fully interchangeable or are there fine differences between them? We believe there are indeed major differences with regard to engineering, design and, above all, the sound! But what distinguishes quadral loudspeakers from the others? Engineering: quadral loudspeakers are conceived in such a way that they can handle even difficult amplifiers with ease, which means that you can combine them with virtually any music system. In the forefront of product development is not only the perfection of individual details but also the minimization of any weaknesses relevant to the sound - graded according to price category. Our aim is not only to harmonize our loudspeakers with diverse music systems, but also with diverse music styles. In doing so, the quality and durability of the materials are crucial factors influencing our choice of components. Furthermore, not only higher-priced models benefit from quadral technologies which are only available as standard in quadral products: quadral ribbon and RiCom tweeters, quadral-ALTIMA© and graphite-coated laminated membranes, pressure chamber reflex cabinets, BTC and runtime correction circuits, etc. Design: Loudspeakers must harmonize with a huge variety of surroundings. Therefore, almost all quadral products are available with a neutral black finish. However, models higher up the range are also available in other colours or real wood finishes. Our styling prefers mainstream to avant-garde - hence the classic, timeless lines and finishes to the cabinets, carefully manufactured using the very best quality materials and much attention to detail. Sound: quadral's No. 1 development objective is not maximum volume when switching over between different loudspeakers, but rather maximum resolution combined with maximum compatibility with all conceivable amplifiers. Therefore, in terms of sound neutrality, precision and attention to detail, quadral loudspeakers always provide maximum listening enjoyment from all normal listening positions. Although the acoustics of many sales outlets reflect a different philosophy, we at quadral intentionally tune our loudspeakers to match the acoustic characteristics of typical homes. In other words, for rectangular rooms ranging from 15 to 50 m2 in size, 2.2 to 3 m high and including the usual items like carpets, curtains, wooden furniture, upholstery, etc. Our aim is for you to be able to enjoy quadral loudspeakers in your home for a long time.. HISTORY: 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. 2010: At the High End show in Munich quadral presented AURUM VULKAN VIII the first time - with very good success. Quality Guide AURUM and quadral – two names, one maxim: Pure quality for the very best of listening pleasure Flexibility means freedom – freedom to enjoy any style of music in the very best of quality There are lots of loudspeakers capable of high-quality music reproduction. Some know how to put over the sheer energy and power of rock music in a superb way. Others have an aboveaverage talent for handling the demanding subtleties of classical music. And there are others that give disco music an authentic sheen or lend contemporary film soundtracks the right audio flair. In short: a lot of the speakers on the market are specialists – but not universalists. You enjoy listening to Mozart but also love the Rolling Stones? You go for the charisma of a saxophone solo played with emotion but also like listening to 80s pop? Then what you need is a loudspeaker that delivers homogeneous, harmonious and at the same time clear and exciting sound – regardless of which style of music you’re listening to. And if you enjoy the sound of complex, effect-laden films your “dream partner” is a speaker unit that has all the necessary qualities for an atmospherically intense film soundtrack reading. Your wishes are our motivation – to develop and build loudspeakers that leave a lastingly stunning impression is our priority maxim. Loudspeakers that impress with clarity and multifacetedness equally as much as with vigour and power. High quality down to the very last detail – the secret behind boundless listening pleasure Designing a loudspeaker that takes any type of sound and turns it into a homogeneously coherent, energy and emotion-laden overall experience is no easy undertaking. The most important bit: behind every speaker there has to be an intrinsically logical concept– a master plan, so to speak. And that, as we see it, means: high quality down to the very last detail, coupled with large portions of engineering spirit and painstaking commitment. Just take a close look at a quadral or AU speaker – let your eyes wander over the precision-fitted chassis, the meticulously finished RUM edges of the cabinet, or the secure connection terminal. Each and every one of our speakers is as good as it is because we have no time for trivialities. Built to the highest standards of craftsmanship and equipped with sophisticated technology, each and every quadral or AURUM louds is designed and configured to give you literally decades of musical and movie soundtrack peaker listening pleasure. We believe innovations have to make sense – and serve the purposes of optimal sound for you at home Not infrequently you can read about new materials and brilliant technical innovations that supposedly lend a loudspeaker unprecedented acoustic verve. In practice, however, disillusionment soon sets in, for these new heights of sound quality are only achieved on paper. Which is why we have this explicit message for AURUM and quadral enthusiasts – and all those who would like to be: We always see each innovation from one single point of view – it should make for perceptible improvement of the sound and not merely make it appear better in the technical data. Examples of this credo can be found in many of our speaker models, for instance “ALTIMA”, a diaphragm we developed and built using the high-tech light metals aluminium, titanium and magnesium and which is already legendary for its superb response in the low/middle frequency range. Our exclu sive materials mix ensures enormous pulse fidelity – and thus authentic and honest reproduction of music and film soundtracks. The working principle used for obtaining optimum bass response in various models in the AURUM range lies in the combination of ALTIMA diaphragm plus pres sure chamber and bass reflex system, and facilitates consistently deep-down, distortion-free basses even when handling dramatic dynamic leaps. We’re well prepared where treble response is concerned too: we don’t confuse clarity with aural aggressiveness nor brilliance with sharpness. Finding the right balance is of importance at all times in everyday life: our speakers already have it built in. Our development engineers are particularly proud of the high-performance ribbon tweeter as used in the top-of-the-range AURUM models TITAN, VULKAN and MONTAN. A superbly homogeneous sonic spread, effervescent brilliance which remains consistent even at higher volume levels, and a wide angle of radiation create the best basis for optimal listening pleasure. Frequency distribution done properly – for a complete, inherently coherent sonic picture Even the very best diaphragm and chassis technology can only then fully unfold its acoustic charisma if a cleanly designed, well thought-out crossover network prepares the way. Our credo here is: Nothing but the best components, as few as possible, as many as necessary. Put into practice, this already ensures the best basis in terms of frequency distribution, and the high-quality chassis units can process the sound in the working range for which they are designed. Fine, gentle, coherent transitions and a mature, complete sonic picture are the audible advantages arising from the painstaking care and finesse we put into our design. The orders for parts such as capacitors or coils for our crossover network systems are placed only with the best suppliers – after all, good sound already starts with the selection of the smallest components. The loudspeaker should make music sound – and not itself Ensuring consistently excellent sound reproduction of all music genres means ensuring that the cabinet itself doesn’t bring itself into play, in other words it should be absolutely rigid and free of vibration. It should also not generate intrinsic sound and instead should serve one purpose only, namely the acoustically authentic reproduction of incoming signals. For this reason our cabinets are not avant-garde design sculptures that are subject to short-lived trends and bring with them dubious acoustic characteristics. We believe in building cabinets featuring timeless design true to the principle of form follows function and the elegantly sober lines of which correspond optimally with absolute acoustic functionality. Also a secret of our success – the effective deployment of incoming power Maybe you know the problem: Here a top-of-the-range loudspeaker, there a premium-class amplifier, yet the sonic picture they produce together just won’t come over as a coherent whole because – seeing as it’s designed solely for optimal fidelity but not for maximum power yield – the amp can’t work with a loudspeaker which for its part is power-hungry and weak in terms of effici ency. This is a problem you certainly won’t encounter with our products. Our speakers are desig ned to offer excellent efficiency, which means you have an absolutely free choice and don’t have to make any type of compromise where signal-generating electronic equipment is concerned. High-quality AURUM or quadral speakers have no problem whatsoever in working with highly sophisticated class AA amp units and guarantee a harmonious, detailed sonic picture. The right partner for all tasks – our multi-channel “experts” Blu-rays, DVDs or SACD and DVD audio discs in most cases have multi-channel sound tracks which in their entirety are translated into sound; this sound is delivered to the listener via a set of loudspeakers generally comprising two front speakers, a centre unit and two surround speakers as well as an active subwoofer. This is why we regard it as matter of course to offer complete, perfectly intermatched multi-channel configurations. Our large and our compact centre speakers too impress with optimal harmonization with the front units and above-average angles of radiation – the result of which is that music, voices and effects come over with equally high degrees of clarity and intensity. Our high-performance active subwoofers are equal to virtually any challenge in the low-frequency range, and thus give modern film productions the right audio foundation. Equipped for the new age: with AURUM into the acoustic HD era Blu-ray has now been established as sole successor to the DVD format, and this means changes to both the visual as well as acoustic preconditions. Drastically increased sampling frequency levels and a significantly greater bit depth as against the DVD enable previously undreamt-of re sults in terms of sound. In the form of Dolby TrueHD and DTS-HD Master Audio there are two HD sound formats available which ensure loss-free compression of the audio data. The result: sound with precisely the radiance intended by the sound engineers when doing the mixing. Greatest possible dynamics, outstanding transparency and incredible acoustic precision are the stunning characteristics of the new HD sound formats. With our AURUM loudspeakers we offer you the right instruments for getting the very most out these formats. Their tremendous frequency response characteristics, superb high-tech chassis units, painstakingly built cabinets and incredibly high power-handing capacity make each and every one of our AURUM sound system components the right companion for entering the acoustic HD age. The bottom line as we see it: Only those who know how to put quality into every last detail can impress and enthuse the true music and film sound con-noisseur in the long term. Loudspeakers stand out agreeably from many other electronic devices. They’re not disposed of after a relatively short period of usage, and can instead develop into a “loyal friend” that provides the user with in some cases even decades of listening pleasure. This makes purchasing loudspeakers something that should be approached carefully and with deliberation. We have no doubts whatsoever that our products will stand up to the closest scrutiny in terms of both looks and sound – after all, our AURUM and quadral loudspeakers are exactly what you’re looking for: loyal, reliable companions that make for daily listening pleasure based on outstanding harmony, acoustic radiance, power and clarity. Irrespective of whether you’re having an intensive listen to Wagner’s Ring cycle or enjoying lounge music in the background during dinner – AURUM or quadral speakers are your guarantee for never failing to find precisely the right combination of homo geneity..
