RD Acoustic Euphoria Atelier Rullit Field Coil + Coral


Überwältigende Räumlichkeit und Spielfreude umschreiben den Euphoria Lautsprecher des Herstellers RD Acoustic recht treffend. Die Originalbestückung von Fostex im Hoch/-Mitteltonbereich sowie die Eminence 15" Bässe speilen schon ungemein natürlich auf. Diese hier angebotene Version wurde jedoch hochgradig modifiziert!


Der Fostex FE206 ( 150€ Stk. ) wurde gegen ein Field Coil Chassis vom Meister Oleg Rullit Atelier Rullit Lab 8 ersetzt und spielt dadurch in einer völlig anderen Liga!! Der Neupreis der Silver Lab 8, wenn man überhaupt welche bekommt, liegen bei 3500€. Jedes Chassis wird in reiner Handarbeit von Anfang bis Ende von Herrn Oleg Rullit gebaut. Im Bassbereich arbeiten nun keine standard Eminence Woofer mehr, sondern unglaublich impulsschnelle Coral 15-L100 Chassis ( Gebrauchtpreise 1500€, eigentlich viel zu günstig ). Diese Treiber spielen auf TAD Niveau und wurden evtl. sogar von TAD produziert. 


Ich persönlich höre seit 5J mit den großen 9" Field Coil Chassis (9K €) in einem offenen Horn, natürlich ohne vorgeschaltete Frequenzweiche ;-). Selbst die großen Feastrex konnten es nur anders, nicht jedoch besser als die Atelier Rullit!!!

The unique construction design of High End speakers Euphoria takes advantage of ideal attributes of a full range driver, which features detailed recitation, outstanding spaciousness and localization of instruments. Euphoria speakers are also equipped with powerful and highly sensitive fifteen inch woofer speaker driver.

Dividing frequency 150Hz for woofer driver is selected as low as possible with a regard to the physiology of human hearing, which in higher frequencies is sensitive on phase shift signals, which is caused by frequency crossover. From the frequency of 150Hz to 22KHz plays upper full-range driver, there is no crossover used in the signal.




Originality of solution, optimization of baffle without any construction design compromises, based on amount of tests, we have created speakers, which bring indescribable detailed listening with powerful bass component.
