DESIGN STATEMENT, SONIC ELEGANCE
The new XB Diamond Mk II is the closest alternative to the X Diamond Mk II, which performs outstandingly in smaller listening spaces. The new XB Diamond Mk II combines the best in sound and design, which is the hallmark of Estelon products.

The XB Diamond Mk II features a 1" diamond tweeter, along with new cabling and a top-of-the-line crossover, that deliver extended high frequencies for a smooth and a resonant-free acoustic experience. The XB Diamond Mk II will intensify the fidelity through its transparency, precision, and the unprecedented detailed reproduction.

Through Estelon’s advanced and innovative engineering concepts, the 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.

The combination of curved cabinet walls and a complex system of interior chambers make the cabinet completely “dead” and non-resonant. Furthermore, the enclosure of each driver system has optimized enclosure geometry to suit specifically for the driver to perform its best. 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.

Room dimensions and characteristics have a significant effect on the listening experience. The pressure at these frequencies changes equally in every position, similar to pressing on a balloon. In these conditions, it is impossible to localize the exact position of the bass driver. This situation allows the placement of the low-frequency driver to be separate from other drivers.

The Estelon XB Diamond’s woofer is positioned close to the floor so that the woofer couple acoustically with the surface of the floor maximizing its efficiency and output. The placement of the woofer close to the floor assists in bass coherency and a more even distribution of room standing waves. This makes it easier to find a suitable listening position in the room, with fewer compromises in bass accuracy.

In frequencies over 100 Hz, there are numerous sound reflections created between the loudspeakers and the walls, ceiling, floor, and furniture/décor. In these higher than low bass frequencies where the wavelength of the sound is short enough for human hearing to be able to detect where the sound originates and to produce localized peaks and valleys in the room due to standing waves, the placement of the driver in relation to other drives becomes significant.

The drivers that reproduce sounds over 100 Hz (mid-woofer and tweeter) are grouped together and physically placed higher in the cabinets. In this configuration, the reflections from adjacent surfaces are minimized. Furthermore, a high degree of coherency can be achieved with a stable stereo image from high bass notes up to the highest harmonics.

Our Story
Since 2010 Estelon is providing the most luxurious loudspeakers to the high-end community. Acoustic excellence through sophisticated engineering, as well as high-quality components, are combined in order to accommodate the brilliance of Estelon sound reproduction systems. Decades of knowledge and experience allow us to produce loudspeakers with a truly rich natural sound, creating an unimaginable musical experience.

The story of Estelon’s chief designer and engineer started decades ago when at a very young age and while growing up in the Soviet era he began to dismantle radios and adjusted their components to improve the sound quality. He took his interest to the university, studying electro-acoustics in St Petersburg. This was the beginning of a journey that led to an important moment back in 2010 when engineer Alfred Vassilkov was having breakfast with his family.

“It was a lovely Sunday morning having breakfast with my family”, Alfred recalls. “I had long held the ambition of creating the world’s best loudspeaker. I knew what the concept would be but instead of selling my idea to a company, I decided to build it on my own. Luckily I already had the best key executives in my family, my daughters Alissa and Kristiina. That same evening we decided to set up the company.”

Alfred was designing speakers for over 25 years before achieving his ambition. He always sought perfection and overcame challenges. Those experiences enabled him to develop technologies and seek materials to construct the most unique and innovative products. These were combined with inspiration from nature – the lush and expansive forest landscapes of Estonia in specific – creating the perfect balance between engineering and design.

The result is Estelon, one of the world’s most luxurious speaker brands. It derives aesthetic and acoustic excellence through the merger of ingenious creativity and cutting-edge science. Each decision – from engineering techniques to materials and components used in the manufacturing process – is made with the perfect harmony of the speakers as a whole in mind.

For Alfred, this flawless synergy is what an engineer strives for in his creations. Every single detail is carefully considered, selected and tested during all stages of the production process. The result is a handcrafted masterpiece of beauty on the outside and the pinnacle of technology on the inside.

Estelon is today regarded as a leading innovator in the audio industry, having received multiple awards for its designs and technological innovations. Two times ‘Innovation Award’ in the Consumers Electronics Show (CES), and a prestigious ‘Red Dot Design Award’, are only the beginning of a very long list of achievements since 2010.

The company’s loudspeakers are today proudly owned by some of the world’s most eminent innovators and global leaders.
