Dynaudio Special Forty Bookshelf Speakers (Ex Demo) Description Laurels aren’t for resting on We still surprise ourselves. Some people might be content to sit back and be complacent about their successes after 40 years of constant innovation. We aren’t. In fact, we only get hungrier for new techniques and technologies. That’s why we developed the Special Forty: we wanted to revisit those innovations and see what we’d do differently this time. What you won’t find here is anything revolutionary. Instead, you’ll discover a look at our past – along with some special sneak-previews of the future. The Special Forty is classic Dynaudio: all the craftsmanship, attention to detail and total love of authentic sound you’ve come to expect. It’s the connoisseur’s choice – a simple pair of passive hi-fi speakers. But it isn’t about looking back, misty-eyed, at past glories and leaving it at that. It’s about using those glories as a platform from which to launch our next set of breakthroughs. Greatest hits… reimagined We do compact speakers really well. We always have. So, as a nod back to classics including the Special One, the Special Twenty-Five, the Crafft and the Contour 1.3SE, we kept the Special Forty pure – if incredibly advanced. Of course, it wouldn’t be an anniversary speaker if it didn’t include some of our greatest hits. But we haven’t just got the old band back together to trot out the same old stuff, unchanged. We’ve remixed, remastered and rearranged things to bring those old favourites into 2017 – and beyond. That’s why it has one of our 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 our 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.  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. Take the new pressure conduit. It’s a shaped vent in the back of the hybrid magnet system that allows more space in the rear chamber. That space lets us pack in more damping material and reduces back-pressure, while the shape itself optimises airflow coming backwards from the rear of the dome. Then there’s the outlet; the aero-coupled pressure-release system. It sits underneath the voice-coil and reduces unwanted pressure build-up that could affect its movement.  Flux optimisation and beam control We love playing with the laws of physics. Physics wins in the end, of course (usually), but we almost always manage to bend it to our will along the way. Just like we have with our magnet systems. The magnet turns electrical energy that flows from your amplifier into the voice-coil, into the physical back-and-forth movement of the driver diaphragm. These movements are very small and very fast (especially in the tweeter), so they need a lot of finesse if you want to hear all that luscious detail and emotion in your music. Behind the woofer Other manufacturers typically put it around the outside edge, leaving the voice-coil hollow. Putting the magnet inside keeps the magnetic energy (or flux) in the optimum position for getting itself wrapped around the voice-coil – where it should be. That means we can use more of its power for a given weight. It also reduces internal reflections because there’s less material for sound to bounce off inside the driver. Second, we use a hybrid magnet for even greater control over the flux and voice-coil movement. An incredibly powerful neodymium rare-earth magnet provides the muscle and flings flux around with abandon, while a ferrite magnet tempers that enthusiasm by gently moving the flux back to exactly where it’s needed most. The result? Symmetrical excursion, a reduction in second-harmonics, and an even more accurate, authentic sound.
