Manger – Zerobox 107 IIeNature of sound.When as a loudspeaker manufacturer youhave a product in your range that is repeatedlyreferred to with the greatest respect as a classicby experts, journalists of the specialist press, professionalsin recording studios and music loversthen you can be satisfied and just a bit proud. Becausehere “classic” certainly doesn’t meanrelying on the “traditional”. Because standstill isalways a step backwards, we insist in the designof the new Zerobox 107 on the retention of thetried-and-tested, while improving on this usingthe latest knowledge.To be exact the new Zerobox 107 is a 1.5 waysystem in the guise of a two-way system, as theManger sound transducer is essentially responsiblefor reproducing the music as authenticallyas possible. Only below 160 Hz do the twowoofers specially designed for the Zerobox 107kick in to support the sound transducer in itsdemanding task. Only the lowest octave between80 Hz and 40 Hz is reserved for the woofers ontheir own. And this constellation also ensures theideal of a punctiform sound source.The demands placed on the crossover are particularlystrict to ensure that the woofers can continuethe transient of the Manger sound transducerfor a natural reproduction with absolute temporalprecision. A 3rd order filter with a precise time delaypreceding the woofer driver provides optimum interactionof the sound components. A closed cabinet also supports thiseffect and allows the woofers to decay in a controlled and idealway. And to ensure that not a trace of the musicality is lost alongthe way, only top-quality state-of-the-art componentsare used in the Manger sound transducer.New findings in the field of physics and materialstechnology have meant that the Manger developercan’t rest on his laurels. The Zerobox 107 hasalso been sensibly overhauled in other areas. Thespecific use of the latest high-tech dampingmaterials from the automotive industry, in additionto the continuously optimised internalstruts, means that the cabinet remains unmovedeven when subjected to extreme pressure.Tried-and-tested technology is however notcompletely forgotten. Three sound transducersare used in every Zerobox 107. This speciallydesigned Manger arrangement does not serve,as is often believed, to achieve surround sound,but to simulate a quasi infinitely large soundbaffle. In this way effects that would otherwisebe caused by a narrow cabinet front are totallysuppressed, and instead it exclusively serves theundisturbed sound propagation of the frontsound transducer.The Zerobox 107 was singled out for thehighest praise and declared a “Reference Speaker”by the German magazine “Stereoplay” as earlyas 1999. That the new version will continue thesuccess of our classic model and not only maintainits qualities but also improve on them is a certainty.Because neutrality will continue to find an evergrowing circle of listeners. Music in its most natural form, just asthe musicians played it, without any artificial technical additives, movesus and fascinates us, because we can feel the music directly.
