Estelon engineering took many years of research and testing to find the right material that would allow the highest quality of cabinet and construction for the loudspeaker’s acoustically engineered complex shape. We developed a proprietary marble-based composite material and special moulding technology to be able to make cabinets with such advanced surface geometry, inside and out.
The unique shape of the cabinet is highly complicated and differs greatly from a classical box design. The combination of curved cabinet walls and a complex system of interior chambers make the cabinet non-resonant. Such a highly advanced and complex cabinet design and construction allows only pure and uninfluenced sound to emanate from the various high-performance driver elements.
In order to assist the loudspeaker to unveil its purest musicality, advanced internal dampening has been implemented. The dampening was designed through a long testing process to have the best effect and overall balance throughout the musical spectrum. We have chosen different natural and synthetic dampening materials. The dampening materials type, placement and amount have been chosen through calculations, measuring and rigorous listening tests.
Each loudspeaker has one woofer, one mid-woofer and one tweeter. In order for the speaker to reproduce the full spectrum of sound with the absolute highest quality, a combination of three different driver types has been carefully chosen. These high-quality drivers are designed and produced by German driver manufacturer Thiel & Partner GmbH under the brand name Accuton and are revered globally as the best.
