Jury of Red Dot 2017

The Experience

The Model YB is yet another unrivaled sonic masterpiece from Estelon delivering the finest sound placing the listeners at the heart of the audio landscape. The asymmetrically designed speakers are a true marvel of sophisticated engineering providing a profound and unparalleled experience in the most exquisite venues.


The Preparation

Alfred and his team follow a meticulous approach ingraining the uncompromising Estelon exclusivity in each of the products. The process involves a scrupulous matching phase where the drivers are paired together depending on the parameters of extensive tests they undergo, where subsequently the integrated system is subject to thorough fine tuning. Finally, the system components are installed into freshly painted cabinets and comprehensively scrutinized to ensure each product is the ‘Estelon sonic masterpiece’.

The Technology

The 8-inch woofer with an extremely stiff aluminum cone, gives tremendous bass precision delivering deep natural bass while a 5.25-inch mid-woofer, known for its sliced paper cone technology where the slices are filled with damping glue, dramatically reduces breakup modes in the diaphragm. Finally, the beryllium membrane 1-inch tweeter characterized by its colossal rigidity, light weight and high damping, allows for negligible distortion and distinct clarity, delivering incredibly powerful sound
