Estelon XB DIAMOND
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.

The Estelon XB DIAMOND marries lively, articulate bass with an open, low-distortion treble, delivering relaxed refinement without sacrificing scale. Its diamond tweeter, ceramic Accuton drivers and sculptural marble-composite enclosure shape a deeply precise, natural presentation; Best of High End highlights its musical openness, while Audiophilepure found its low end impressively extended and controlled.
What Reviewers Are Saying
Pros
Lively, articulate bass reaches close to full-range depth and remains strong through acoustic-bass and grand-piano fundamentals.
Diamond-tweeter and crossover design supports an open, natural, relaxed and precise presentation with very low audible distortion.
Plays loudly with ample headroom and no reported sense of running out of power.

Cons
Does not deliver the ultimate physical low-bass impact of Estelon’s larger Forza model.
Its $60,000-plus pricing places it firmly in the rarefied high-end category.
SOUND QUALITY PERFORMANCE 88/100
Available coverage describes a refined, relaxed and highly resolved presentation, with particularly convincing bass extension and articulation. The evidence is thinner on imaging and midrange character than on the low end, while high output appears available without audible strain in the reviewer's listening.
Bass
91/100
Audiophilepure found ample, lively and articulate bass, reaching close to the lowest grand-piano notes while retaining full level through the range of acoustic and electric bass. It fell short of the much larger Estelon Forza's physical low-bass “massage,” so it is not presented as the ultimate room-pressurising design.
Mid
86/100
Best of High End calls the dedicated mid-bass unit neutral and describes the overall sound as natural and relaxed. There is little independent listening commentary specifically addressing vocal tone, instrumental body, or crossover integration.
Treble
89/100
The available description credits the diamond tweeter and crossover with an open, musical and precise presentation, free from audible distortion. Review material does not identify glare or hardness, though direct comparative listening observations on treble balance are limited.
Soundstage Imaging
86/100
Best of High End characterises the presentation as open, deeper and precise, suggesting a spacious and well-defined image. The reviews provide little detail on stage width, image placement, layering, or sensitivity to room positioning.
Dynamics
88/100
Audiophilepure reports more than ample maximum volume and says it never approached the speaker's limits in use. The reviewer does caution that ceramic-driver speakers may not be the first choice for party-duty abuse, and there is limited direct discussion of transient punch or large-scale orchestral slam.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
85/100
The marble-based composite enclosure is described as integral to the loudspeaker rather than merely decorative, and the published design details point to carefully isolated crossover components and sophisticated drivers. However, the supplied reviews offer little hands-on appraisal of fit, finish, terminals, or long-term durability.
Value for Money
85/100
At roughly $60,000 to $79,700, the XB Diamond competes in a rarefied high-end segment where finish, engineering and system matching are expected to be exceptional. None of the supplied reviews directly assesses whether it represents strong value against rival floorstanders at this price.
