Dynaudio Special Forty – A Timeless Classic, Reimagined

Laurels Aren’t for Resting On

After 40 years of innovation, we’re not slowing down. The Dynaudio Special Forty is a tribute to our legacy—bringing together decades of craftsmanship, cutting-edge technology, and a vision for the future. This isn’t just a nostalgic look back; it’s a leap forward in high-fidelity sound.

Greatest Hits, Remastered

Drawing inspiration from our legendary compact speakers—like the Special One, Special Twenty-Five, Craft, and Contour 1.3SE—the Special Forty stays true to its roots while incorporating groundbreaking advancements. Its expertly tuned crossover ensures seamless signal distribution, while phase and impedance alignment technologies optimize performance for an immersive listening experience.

Precision Engineering for Unmatched Sound

Esotar Forty Tweeter

  • The new Esotar Forty tweeter maximizes airflow for refined, crystal-clear highs.
  • Its low resonant frequency smooths the transition between tweeter and woofer for natural sound reproduction.

17cm MSP Woofer

  • Engineered with a hybrid magnet system, this woofer minimizes distortion while handling higher power effortlessly.
  • Based on our acclaimed Confidence and Evidence ranges, it delivers deep, accurate bass with remarkable detail.

First-Order Crossover

  • Utilizes Phase Alignment and Impedance Alignment technologies for exceptional audio clarity.
  • Ensures precise frequency separation between drivers, optimizing overall balance.

Innovative Airflow Optimization

The Special Forty’s AirFlow Basket minimizes internal reflections and enhances airflow for a purer sound. Behind the woofer, our pressure conduit and aero-coupled pressure-release system reduce unwanted resonance, allowing for an incredibly detailed and dynamic performance.

Flux Optimization & Beam Control

By placing the magnet system behind the woofer, we ensure optimal energy transfer to the voice coil—improving efficiency while reducing internal sound reflections. The result? A more natural, distortion-free listening experience.

New 2020 Finishes – Black Vine & Ebony Wave

The Special Forty now features two stunning new finishes:

  • Black Vine – A deep, dark veneer highlighted with vivid orange streaks.
  • Ebony Wave – A luxurious, sinuous take on classic hardwood.

Both finishes are meticulously crafted to ensure consistency between pairs and a smooth, high-gloss finish that radiates elegance.
