Quadral Montan VII

The one dough er box for Ribbon lovers: cultivated, balanced and accurate bass.

  1. Quadral Montan VII
  2. Data sheet

The Roman written “VII” Herald at Quadral indeed the generation number of Aurum series. Where it counts VII Montan in 25 years existing series to the most compact boxes, construction and tuning templates whether even the previous Quadral developer Berndt Stark.

The bass must be behind bars

Here he used state of the art chassis material with slight retro-chic, for the silver glimmer of low and midrange, “Altima” draws a mixture of aluminium, titanium and magnesium responsible. It will the Physical combine the advantages of all three metals and from the outset prevent characteristic resonances, which is said to especially the magnesium. By 26 centimeters the bass has a stately measure, which plays in a pretty unusual environment: he is indeed not sharp as a razor, yet he must be behind bars. Quadral calls this construction somewhat misleading “Hyperbaric chamber”, it has however nothing to do with a band-pass filter: the air in front of the membrane resonates not as its own mass, but is coupled to only gentle different pressure conditions close to membrane and free-field, which aims to improve efficiency and thus distortion.

The shining star of the chassis team is of course the tweeter which is called “Ribbon” in the Quadral brochures. This is not a classic Ribbon, which swings a live metal foil in a strong magnetic field, but actually a Magnetostaten: a non-conductive foil, on the multiple traces are glued, what considerably increases the efficiency of compared to the classic Ribbon and problems with low impedance from the outset avoids. However, Quadral has some tricks up its sleeve: the horizontal dispersion angle to increase the slots of the massive grille were relatively long and narrow; vertical angle of radiation not grown so however. And scoffers like away to remember the shape of the box on a headstone. Had said, however, that both the acoustic purposes of the beveled edges and the superb quality of real wood completely beyond doubt are.

Hearing test

Those who had expected a biased notion given the Visual dominance of bass and tweeter, was the Montan disabused: timbre true and discreetly, with never presumptuous heights she played up by the fairly bright mixed “fire magic” (Wagner, “Valkyrie”, Karajan, DG), it combined the detail of a Ribbon with the homogeneous style of play in a dome. Thus, she quickly won the sympathies of the AUDIO Mr Bernhard Rietschel, who praised their impulsive, crunchy bass as well as the balance even borderline recorded CDs (Lyn Leon, “Private Pop”). The dynamic test with “Let there be light” (Haydn, “Creation”, Amber) mastered the chassis team with flying colors, even in FORTISSIMO’s did not lack of overview and clarity. Because the editors had to access very far above on the shelf, to capture the Quadral: the Revel Performa F-52 in a similar tonal vote offered the other room, the drier bass, the better imaging, but she trumped the round and detailed performance of the Quadral only in more subtle disciplines of speech punished. The Geithain ME 150 offered as a steeper and more brilliant idea, had to give in but small the Quadral given quantitative superior power.

The establishment of

When verifying various installation variants the massive box with the wide chassis had however proved to be a cat: who stops above the height of your Ribbon – or even standing -, experienced a rather musty, lackluster transducer. Who prepares the VII with their backs to the wall, its bass precision will remain probably hidden behind an imprecise thunderstorm rumbling.
