What do trade magazines say about this product?

Reduced design – acoustically to the point

You won´t find any extravagance, decorative elements or embellishments here! Instead, the Edelstein is convincing with simple elegance, high-quality craftsmanship and a touch of noblesse.

Stylish aluminium front for optimum acoustics

The targeted mechanical coupling of the silk dome tweeter to the solid aluminium front panel ensures optimum dispersion characteristics with low inherent vibrations.

Perfect looks even from behind

The milled aluminium connecting terminal with gold-plated, totally insulated screw terminals also allows the use of larger-gauge cables.

Perfect acoustic decoupling

The silk dome of the tweeter is perfectly balanced acoustically. The especially wide surround offers optimum dispersion characteristics in combination with the special sound guide in the aluminium front panel.
