Electra 1000 Be 2
Electra 1000 Be2, high end hifi speakers
From Aluminium / magnesium to Beryllium
In 2003, the Utopia line inaugurated a revolutionary technology: the pure Beryllium inverted dome for which Focal now holds two manufacturing patents. Ultra-light (21mg), but rigid (7 times more rigid than titanium or aluminum for the same volume-mass), Beryllium possesses absolutely fantastic properties to create an exceptional tweeter. Add to this the capability to surpass 40kHz without break-up, and at high-pressure levels. Last but not least, it stands out with excellent linearity thanks to its high internal damping, which inhibits resonance and distortion at the far reach of its frequency range. For Electra 1000 Be, we decided however to direct our attention to an entirely other direction, as we felt that there remained other challenges to pursue and that the 40kHz that we had achieved was certainly sufficient for perfect reproduction of treble. Our new goal with the IAL (Infinite Acoustic Loading: the creation of an extremely high-bandwidth tweeter, that would be able to descend in frequency as far as possible, in order to take over from the midrange as early as possible. The stakes: create a design where the critical frequency range of 2000 to 5000Hz, where the ear is most sensitive, can be reproduced by an ultra-light tweeter dome. The 2009 version, which dome diameter goes from 25 to 27mm, optimizes the recovery of the cut-off frequency and improves dynamics and precision.
Mediums and woofers are the same quality as the previous high end Electra 1000 speakers.
