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.
Cutting-edge acoustic technology in a classic Dynaudio design
The 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.
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.

The principle behind a Dynaudio tweeter
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.
