Cutting-edge acoustic technology in a classic Dynaudio design

The new Special Forty anniversary speaker draws on 40 years of cutting-edge research – and brings it totally up to date with Dynaudio’s most celebrated techniques and technologies.

  • Esotar Forty

    The new Esotar Forty tweeter maximises airflow for even more refinement, while its low resonant frequency smooths the transition to the woofer

  • 17cm woofer

    Our best 17cm woofer yet. It’s based on what you’ll find in the Confidence and Evidence ranges, and uses a sophisticated hybrid magnet system for lower distortion and higher power.

  • First-order crossover

    Phase Alignment and Impedance Alignment technologies keep this classic Dynaudio crossover topology firmly on top of its game.

  • Special finishes

    The Special Forty’s exclusive Grey Birch High Gloss and Red Birch High Gloss finishes are as striking as they are beautiful – and are unique to each speaker.

The shock of the new Dynaudio Special Forty speakers

Listening to the Dynaudio Special Forty, you realize sometimes the smaller speaker is the right speaker.


Do you know about Dynaudio speakers? Designed and made in Denmark, the latest speakers from the company are understated by high-end standards. The Special Forty can fit in with any decor, with a sound that’s similarly low-key, but that’s why they’ll wear well over time. Dynaudio makes pro and consumer speakers, and I’ve certainly enjoyed my share of them in home theater and high-end stereo audio systems over the years. Speaking of years, Dynaudio is celebrating its 40th anniversary with its Special Forty speakers, so I spent some quality time with a pair at the In Living Stereo store in NYC.

I like that its trim size is so apartment friendly at 7.8 x 14.2 x 12.1 inches (198 x 360 x 307mm), and the high gloss stained grey or red birchwood finishes have a cool modern look. The Special Forty are expensive little speakers, but sound and build quality are commensurate with the price and celebration of the company’s 40th anniversary.

Dynaudio is known for its drivers, so this new speaker sports a precision-coated 1-inch (28mm) soft-dome tweeter that is unique to the Special Forty. The 6.7 inch (170mm) mid-woofer design is based on Dynaudio’s flagship Confidence and Evidence designs, and the Special Forty woofer uses a sophisticated hybrid magnet system to lower distortion and create higher power output. The tweeter and woofer both use aluminum voice-coils that are lighter than traditional copper coils, which allows Dynaudio to make larger voice-coils for a given weight, and that’s a good thing because larger coils exert better control over the dome or cone’s movement, which further lowers distortion. The company relies on extensive measurements and listening tests in the development of new designs.

For this review the Special Forty was partnered with a Naim Nait 5si integrated amp, a Naim CD5 XS CD player and a Rega PL3 turntable. I also checked out the speakers sound with the spectacularly good Line Magnetic 518 tube integrated amp.

How special is it?

The Special Forty is in step with the trend of shrinking high-end speakers size, and this speaker might be the best one yet for its size. Tonally, the Special Forty is smooth and easy, but as I continued to listen it was the speakers’ clarity and resolution that made the biggest impressions.                                                                                   READ MORE
