Product Highlights

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 Esotar Forty tweeter

This DSR precision-coated 28mm soft-dome tweeter is unique to the Special Forty.

Our best 17cm woofer yet

The ultimate incarnation of our legendary 17W75 MSP woofer, with an AirFlow Basket and hybrid magnet system.

Classic Dynaudio crossover

This is a variant of the first-order crossover used in our other classic two-way speakers – and its performance borders on the mesmerising.

Special finishes

Striking Grey Birch or vivid Red Birch? Either way, your eyes are in for a treat.

Aluminium terminal plate

Five-way binding posts and the 40th anniversary logo: we care for the bits you don't see too much, too.
