Attention to detail everywhere
This satisfying thoroughness – which certainly leaves its mark on the cost of production – is equally visible in the matching stands, which make their proud price of 750 Euros for the pair seem much more justified than is generally the case. After all they have a sheer mass of around 18 kilos, a very stable and at the same time multiple times decoupled base and a well-designed cable duct, so that the wires aren‘t just dangling around.
In addition to these exterior features, the 15 kilo two-way ported loudspeaker also has the technical necessities to ensure some sleepless nights for the competitors. So let‘s take a look at the ingredients that have been combined in England to make the Platinum: first there‘s the AMT tweeter, which, in this loudspeaker, plays so beautifully mild and rich in detail that you wouldn‘t recognize it for its design concept. The reasons for this include the acoustically open design of the drive at the front and rear, as well as the dimensions of the especially tightly folded foil, which have been optimized in the course of countless experiments.
This enables, first of all, a frequency response that is unusually smooth and extends downwards, while the powerful neodymium drive further achieves an efficiency of just below 95 dB. This allows the level to be adjusted to the midrange/bass driver, which is also built in-house, and to be reduced by several dB using resistors. This in turn reduces distortion and increases the dynamic range. Experiments were also carried out with the dispersion characteristics until an optimum compromise was found between still high efficiency and a dispersion and energy distribution suitable for living rooms. To prevent unwanted vibrations from irritating the tweeter during its work, it has been screwed to an internal rear panel with a fixed bolt – as can be seen on the sectional drawing.
