Pair of Dynaudio Special 40 Monitor Speakers in Ebony Wave Finish

DYNAUDIO SPECIAL 40TH ANNIVERSARY?LOUDSPEAKER

CUTTING-EDGE ACOUSTIC TECHNOLOGY IN A CLASSIC DYNAUDIO DESIGN

Dynaudio just unveiled its?brand-new?40th?anniversary loudspeaker – the Special Forty?– at?the 2017?High End?Show?in Munich. The team in Dynaudio Labs used?the anniversary edition project?as an opportunity to?study and improve some of Dynaudio’s most celebrated technologies?– making new steps in?tweeter, woofer and crossover?design in the process.

?THE DYNAUDIO SPECIAL FORTY FEATURES:

• A brand-new tweeter: the Esotar Forty, exclusive to this model
• A specially optimized?all-new?17cm woofer
• Classic Dynaudio first-order crossover topology
• Two unique?high-gloss?finishes:?Ebony Wave

The Special Forty’s new?tweeter and woofer?both utilize extended frequency ranges?to improve the integration between the drivers. The technologies of the Esotar Forty tweeter are based on the venerable Esotar2, and its robust design allows it to effectively play down to?the upper midrange –?around 1000Hz?–?without adverse effects. The Esotar Forty tweeter includes a precision-coated soft-dome diaphragm, a new, ultra-powerful high-grade neodymium magnet, a new magnet system with optimized airflow, a new reflection-absorbing felt ring, and Dynaudio’s signature ferrofluid-damped aluminum voice-coil. Performance is highlighted by a significantly lower resonance frequency and further minimized distortion.

The woofer?– Dynaudio’s best?17cm model?yet?–?can easily handle?frequencies up to?4000Hz?thanks to Dynaudio’s proprietary Magnesium Silicate Polymer (MSP) diaphragm material and the geometrically optimized?one-piece moulded cone design.?This?uses the centre of the cone to reproduce midrange frequencies by coupling it directly to the voice-coil. The woofer features a new, higher-grade neodymium magnet utilized in an updated hybrid magnet system, a new fiberglass voice coil former, a new Nomex spider suspension, and optimized mechanical symmetry to minimize distortion and maximize power handling.

Dynaudio’s engineers have taken great care to ensure that the frequency?overlap happens in the drivers themselves, rather than correcting or tweaking the signal in the crossover. The phase-aligned and impedance-linearized crossover is derived from classic Dynaudio?first-order?topology –?something the company has been?continuously?refining for decades.?Select?high-grade?components and?Dynaudio’s?40 years?of design?experience have made it incredibly refined. Internal wiring is high-quality OFC copper wire sourced from van den Hul.

OTHER INNOVATIONS:

The?AirFlow Basket?(which holds the driver motor securely in place in the cabinet?without transferring unwanted vibration): Its?specially?shaped?aerodynamic?ribs reduce internal reflections and?help?improve?airflow behind the cone?without compromising the basket’s stiffness or stability

The woofer’s?hybrid?magnet?system: This sits inside the voice-coil rather than outside in order to better?immerse?the voice-coil’s aluminium wire in?magnetic flux?for more power and better efficiency.?The?magnetic energy is supplied by the powerful neodymium magnet, while a gentler ferrite magnet controls its direction to where it’s needed most:?around?the coil. The?two?exclusive?finishes: The Special Forty takes?Dynaudio’s?celebrated?anniversary-model?finishes to a new level with?high-gloss lacquered Grey Birch and Red Birch cross-cut sandwich veneers. Both vividly highlight?the wood grain for a truly striking appearance

Otto J?rgensen,?Dynaudio?Product Manager, says:?“We didn’t want to rest on our laurels with the Special Forty. We’ve studied the techniques and technologies that brought Dynaudio so much success in the past, and brought them up to date in our new Dynaudio Labs facility. We wanted to?revisit those innovations and see what we’d do differently this time?– and Dynaudio’s 40th?birthday was the perfect time?for it.”
