Estelon Model XB Floorstand Speaker :
The Estelon XB is much awaited addition to the Estelon X-Series. Sharing the signature E-lon shape with Estelon XA and Estelon X Diamond, it is a speaker designed for smaller listening rooms while keeping the hallmark of Estelon loudspeakers – the wide imaging, deep sound staging and thrilling life like dynamics. The Estelon XB surprises its listener with a very defined and deep bass, clear and articulate mid and exceptional dynamics in high frequencies. The Model Estelon XB reproduces the finest nuances of music, giving the listener an impacting emotional experience.
The most noticeable and important technological advancement is the design and the materials used in building the Estelon’s speaker cabinet. Cast with the patented marble based composite and designed specifically to enhance the elements inside it, it is not simply an asthetic visual element, but one of the leading reasons why the sum of the speaker is bigger than its parts.
The 220 mm German made Accuton bass driver uses a special ultra stiff ceramic – sandwich dome. FEA optimized overhung motor design with 38 mm titanium voice coil former guarantees very low energy storage and good heat transfer. The mid-bass unit, developed by Accuton, is a sophisticated design with special attention paid to the titanium voice coil former and the surrounding air gap to provide maximum freedom from dynamic compression in conjunction with the use of a special ultra stiff ceramic dome. It is valued for its midrange neutrality, mated to its own acoustic enclosure. All moving elements of the driver are ventilated for resonance free response. The new 25 mm high frequency driver has ultra hard ceramic dome and no ferrofluid filling. A unique FEA optimized underhung motor design with vented aluminium voice coil former and double neodymium magnet guarantees low energy storage, excellent heat transfer and high excursion capability for low power compression and ultra low distortion around.
Each drive unit is “broken in” by running a signal through them for several hours before selecting matching pairs of drivers for each speaker pair. When drivers in matching pairs, another ‘break in’ with a special signal is conducted. Finally, drivers are fitted into the finished cabinet for individual tuning.
The components used were chosen through hundreds of listening tests based on subjective musicality – drivers, Teflon hybrid capacitors, inductors, Kubala-Sosna internal wiring etc. All of the aforementioned is unified by Alfred’s custom crossover, that enables the symbiotic performance of the elements after they are carefully tested – the crossover with Teflon hybrid capacitors and air core inductors is incased in a separate chamber to protect the crossover components from microphonic effect.
