Xavian Designs Speakers Featuring Only Scan-Speak Ellipticor Drivers

Coming from the Czech Republic, Xavian is the first hifi company to do what many speaker designers have dreamed of doing. They designed a speaker completely relying on the advanced Scan-Speak Ellipticor drivers. Exploring the benefits of an elliptical voice coil to defeat cone and dome standing wave modes, the new Medea speakers from Xavian feature an 8.5" Scan-Speak Ellipticor woofer and 4.7" Scan-Speak Ellipticor silk dome tweeter in a simple two-way bass reflex wooden cabinet with a very simple, passive crossover design.

Passive crossover filter networks for multi-way loudspeakers generally require a resistive termination for optimum performance. The driver itself generally presents a reactive load. Inductive rise with frequency above resonance of the loudspeaker electrical impedance is semi-inductive due to eddy current losses. The L2/R2 impedance model represents the electrical impedance as seen by the amplifier output. An improved compensation network can be realized by using the analogous circuit “dual” of the L2/R2 model. This represents a dramatic improvement to the basic two-component Zobel network and compensates for the non-ideal semi-inductive behavior of the loudspeaker driver across the entire frequency band.

Amadeus has begun shipping its latest offering for the Hi-Fi community, passive versions of their award-winning Philharmonia speakers co-designed by world-renowned architect Jean Nouvel. Following the success of the original self-powered and digitally processed speakers created specifically for the Philharmonie de Paris recording and mastering studios, Amadeus received enquires for a passive and more affordable version, directly targeting listening rooms for audio enthusiasts, which was no small challenge.

Among the several products introduced at this year’s NAMM Show, Eminence confirmed a series of new drivers already scheduled for 2018. From small format pro audio devices to a 15” neodymium guitar speaker, Eminence has expanded its lineup of audio solutions for a wide array of applications. New Eminence drivers for 2018 include the Alpha 2-8, and Alpha 5-8 for compact pro audio applications, the APT30 horn loaded tweeter, SD28 soft-dome tweeter, and F151M-8 ring radiator compression driver.
