Estelon X Diamond

price on demand

The Estelon X-Diamond – a process of evolution from within. The result of a reassessment, a further refinement and extension of the performance goals already in place for the much praised Model XA – Alfred Vassilkov’s first tribute to the Estelon brand and the birth of a new approach to loudspeaker design. Chief among the physical design elements continues to be the use of the E-lon cabinet form. This cabinet form, having been developed and honed over a five year period, its design and construction allow it to easily couple with even difficult room acoustics. Our respect for the Model XA and its design continue and remain a constant source of inspiration. An evolution – the X-Diamond shares only a common exterior cabinet design with the Model XA, where only the outside body dimensions remain the same. New are the diamond tweeter, mid-woofer, crossover – employing premium quality components in a separate chamber, utilizing state of the art carbon fiber resonant control and isolation technology. In addition changes to the cabinet’s inner layer constrained layer construction, and the dampening materials employed.

Many years have passed since the genesis of the Estelon project and much has been learned during this visionary period – embodying all the visionary achievements – the roots and the choices that have evolved into the Estelon sound. With the X-Diamond, the most beloved element of Estelon products has been reaffirmed – Simplicity. The “minimal” electrical second order crossovers, the raffinated mix of other elements as drivers and acoustic enclosure, has allowed Estelon to find again, trusted and confirmed qualities, a rediscovering and refinement of old but never obsolete design principles and technological principals that are the true expression of Estelon’s sonic esthetics.

The X-Diamond is far more than simply speaker drivers in a cabinet. It is a genuine musical instrument in its own right. One that, when carefully integrated into system and room, is capable of connecting the listener to music in a most profound way. Everything expressed naturally and simply with balance, order and measure. It possessed an eminently musical temperament that is immediately evident upon your first and each subsequent listening experience.

Emotional. Involving. Engaging. A simple perspective of balance – perfect, captivating, providing exceptionally wide imaging, deep sound staging and thrilling life like dynamics, while building and delivering expectations of refined power and listening pleasure.

Cabinet Design – The Estelon X-Diamond continues the integration of the many lessons learned from Alfred Vassilkov’s more than 25 years designing loudspeakers. The E-lon shape – choices of material and time-honored construction techniques, a special casting process, the use of a proprietary marble based composite and the extensive use of sub-structural stiffening spars breaks up resonance nodes and creates an internal acoustic chamber of non-parallel sidewalls that is all but immune to unwanted standing waves that can cause a colored sound. The X-Diamond continues this tradition, while employing selected changes to the cabinets’ inner layer constrained layers as well as the selected dampening materials. During the final hand-assembly process each speaker is individually tuned to maintain uniformity from unit to unit. Unusual in its defined form, the results of this cabinet construction allows it to be easily couple with even difficult room acoustics – allowing bass to roll effortlessly into the listening space. Here, the form is more tightly tailored and the reduction in overall scale works to its advantage allowing it to be easily integrated into a variety of listening spaces.

Transducers - The drive units employed are the highest expression of transducer design. The 280 mm German made Accuton bass driver uses a special ultra stiff ceramic – sandwich dome, with an FEA optimized underhung motor design with 55 mm titanium voice coil the former guarantees very low energy storage and good heat transfer. The mid-bass unit, from Accuton, is a sophisticated design with particular attention paid to the titanium voice coil former and the surrounding air gap to provide maximum freedom from dynamic compression in conjunction the use of a special ultra stiff ceramic dome – valued for its midrange neutrality, is mated to its own acoustic enclosure. All moving elements of the driver are ventilated for “resonance free” response. This unique technology allows the X-Diamond to produce bass and dynamics that belie the size of the loudspeaker enclosure. The 30 mm high frequency driver has ultra hard diamond dome. As the dome breakup frequency is around 45 kHz, no distortions in audible frequency range. A neodymium overhung motor design with vented aluminum voice coil former guarantees low energy storage and excellent heat transfer. The soft fabric surround and ferrofluid with high viscosity center the moving parts with distinctive linearity. Each driver unit is “broken in” by running signal through them for several hours before being fitted into the cabinet, and finally – the speakers’ individual tuning.

Crossover – A “minimalist” design 2nd order crossover is used mainly for the natural sound such a design affords. All component parts used, as well as the application of specific internal wiring, are of the highest quality and were chosen through extensive listening tests based on subjective musicality. Crossover with Mii Teflon hybrid capacitors and air core inductors is incased in a separate chamber, utilizing state of the art carbon fiber resonant control and isolation technology Often, seemingly minor changes greatly affect the final sound! Such attention to detail is readily apparent upon first hearing. The result – a totally coherent signal path, a claim proved out based from extensive A/B listening.

Finish – Just as in the making of a great musical instrument, the finish has a profound effect on the final sound! After casting, the proprietary marble based composite is allowed to age, prior to the application of a multi layer internal resonance compound. Only after this time consuming process does the preparation of the surface of the cabinet commence. Manual labor hand sanding and sealing, layer upon layer, applied using an elaborate and time-consuming procedure. And finally the multiple coats of the lacquer finish is applied – hand sanding accompanying each finishing coat. Final polishing – to a mirror-like finish, again, is done by hand. The Estelon’s X-Diamond is offered in a choice of liquid gloss or matte finishes or the optional premium finishes.
