ESTELON X DIAMOND

Unrivalled musicality,
superior precision.

The Experience

“The Estelon X Diamonds get my highest and most enthusiastic recommendation,” Jonathan Valin, The Absolute Sound

The graceful exterior of the new X Diamond Mk II boasts the same sweeping silhouette as its predecessor; however, its soaring cabinet houses a host of technological developments resulting in one of the most sophisticated full-range speakers on the market.

The X Diamond Mk II system’s engineering advancements include a new ultra-hard diamond tweeter and a new crossover network with improved components for a wider dynamic range and transparency. The X Diamond Mk II incorporates new cabling that contributes to an exhilarating audio experience.

  • All Estelon products are produced in a similar fashion using the same general design and construction principles. In the design and construction process, Through advanced and innovative engineering concepts, our loudspeakers form a synergy with the room and its acoustics to re-create an emotionally involving listening experience that exposes the soundstage and musical details of the recording, as it was meant to be heard.

    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 combination of the high-density, solid mass of the moulded marble-based composite and the purposeful shapes, and various internal chambers, results in characteristics that allow for close to perfect acoustical properties. The cabinet is extremely rigid, highly dense, resonant-free, and with exceptional internal dampening and acoustical control.

  • The unique shape of the cabinet is highly complicated and differs greatly from a classical box design. There are no parallel walls, almost every surface inside is curved. 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. The 86 kg (190 lbs.) weight of each speaker gives it static and dynamic stability. This provides a solid foundation for the explosive acceleration of the driver membranes. There is no compression effect in macro dynamics and no confusion or uncertainty in subtle micro-dynamics of the sound.

    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.

    The crossover components have been chosen from among the absolute best available, and the synergy of the end result has been a significant deciding factor. Every component is measured to yield perfect pairs. The crossover filters are in their own isolated chamber to reduce the microphonic effects and vibration influence. The crossover filter slopes between woofer and mid-woofer are third-order, and second-order between mid-woofer and tweeter. Each crossover construction process involves careful attention from our engineers and designers, where every process is carefully thought out and each component tested to make sure that the final result is perfect. After passing technical measurement tests, the finished speaker is put through extensive critical listening tests.
