Greatest hits… reimagined

Dynaudio is heel goed in het ontwerpen van  compacte luidsprekers. Dat hebben e altijd gedaan. Dus, als een knipoog naar klassiekers zoals de Special One, de Special Twenty-Five, de Crafft en de Contour 1.3SE, hield Dynaudio de Special Forty puur – zij het ongelooflijk geavanceerd.

Natuurlijk zou het geen jubileumspreker zijn als het niet enkele van Dynaudio’s grootste hits bevatte. Maar zij hebben niet alleen de oude band weer bij elkaar gekregen om hetzelfde oude spul uit te draven, onveranderd. Dynaudio heeft dingen geremixt, geremasterd en herschikt om die oude favorieten naar het heden te brengen – en daarna.

That’s why it has one of dynaudio’s classic first-order crossover designs, incorporating our unique Phase Alignment and Impedance Alignment technologies. The crossover expertly marshals the input signal between the woofer and the tweeter – so each driver gets only the frequencies it’s supposed to, and can perform at its very best. Its specially selected components handle the impedance optimisation and, because both drivers have extended frequency ranges for even better overlap and integration, that performance borders on the mesmerising.

The song remains the same

The Special Forty uses Dynaudio’s proprietary MSP (Magnesium Silicate Polymer) material for its main driver. MSP delivers precisely the right combination of rigidity, damping and stability for the most faithful sound reproduction. And, unlike other cone materials, it doesn’t change over time – so your Special Forty speakers will still be singing just as sweetly come our next anniversary.

The cone itself uses a painstakingly developed symmetrical excursion for even better midrange performance. Behind it sits our asymmetrical spider – our passive harmonic rectifier. It minimises upper harmonics to further tighten the performance and make it possible not only to pick out individual parts in a piece of music, but even individual instruments in an orchestra. (So now, finally, the Third Violin section can have its day in the sun.) And, like all our other MSP cones, it’s a one-piece design (you can tell by the special balance ribs around the central dust-cap). This gives it an incredibly solid connection to the voice-coil, as well as stabilising its form – which is crucial when you decide to turn it up to 11.

It all sits in our special AirFlow Basket – the bit that holds the whole driver motor securely in place in the cabinet. Its development was one of those ‘Eureka!’ moments our engineers seem to get a few times a week in Dynaudio Labs (you can often hear them cheering from across the road in our factory). We asked them to reduce internal reflections and increase air movement without compromising the basket’s stiffness or stability, and this genius design is what they came up with.

Airflow is king

The new Esotar Forty tweeter takes air-movement to another level. It moves the air in typically sweet fashion in front of the DSR (Dynaudio Secret Recipe) precision-coated soft-dome, of course, but there’s a lot of engineering going on behind it as well.
