The Dynaudio Special Forty anniversary speaker is classic Dynaudio: all the craftsmanship, attention to detail and love of authentic sound you’ve come to expect – plus some cutting-edge innovation.
This wouldn’t be an anniversary speaker if it didn’t include some of Dynaudio's greatest hits.
The Esotar Forty tweeter
Totally new, totally exclusive to the Special Forty… and totally amazing. In the Esotar Forty soft-dome tweeter, the team in Dynaudio Labs have tweaked airflow, lowered the resonant frequency and minimised distortion. Meanwhile, the DSR (Dynaudio Secret Recipe) precision coating finesses the diaphragm’s performance without letting its transient response waver or compress.
Dynaudio's best-ever 17cm woofer
Dynaudio has been making great 17cm woofers for years – but that’s no reason not to tinker, so they decided to see if they could do even better. The Special Forty driver has an improved spider, optimised symmetry and a new, highergrade neodymium magnet for an even clearer, more honest performance.
Seamless driver overlap
Dynaudio used their classic first-order crossover techniques and ramped-up unique Phase Alignment and Impedance Alignment technologies. Specifically selected components handle the impedance optimisation and, because both drivers have extended frequency ranges for even better overlap and integration, their performance borders on the mesmerising.
The woofer and Esotar Forty tweeter both take airflow to another level with new pressure conduits, shaped vents, optimised baskets and more – all serving to reduce unwanted pressure build-up and resonances. The woofer’s hybrid motor system, meanwhile, carefully manipulates magnetic flux for more power, less weight and far more controlled sound.
