Ik heb (als 1e eigenaar) 2 van de uiterst zeldzame 500 paar
Geleverd met certificaat (foto 2)
Voor beschrijvingen, zie foto's 13 t/m 16
Voor technische specificaties en afmetingen, zie foto 17

De luidsprekers op de foto's hebben als serienummers: 945/946, en worden momenteel als achterluidsprekers (rear) gebruikt.
Ik ben bereid in plaatst daarvan het andere paar met serienummers 265/266 te verkopen, dat momenteel als voorluidsprekers (front) wordt gebruikt (zie foto 18).

De luidsprekers kunnen alleen worden beluisterd i.c.m. mijn Audio/Video set (zie foto's 18 t/m 21), (SA)CD's, DVD's, en d.m.v. YouTube video's:

The Beryllium tweeter (Bron: Focal)

A RARE AND PRECIOUS MATERIAL
Beryllium is so rigid that it is the only metal that can scratch glass. It's the material of choice for tweeter diaphragms! Its price - it's 50 times more expensive than gold - makes it a material to be reserved for the best expected acoustic renderings. Today, Beryllium tweeters are used in exceptional Focal products.

EXTENDED FREQUENCY RESPONSE TO 40 KHZ
After two years of research and development, Focal has achieved a world first with the shaping of an inverted dome in pure Beryllium capable of covering more than five octaves (1,000 Hz - 40,000 Hz). What's the point of seeking an extended response to 40 kHz when the human ear hears down to 20,000 Hz? The more extended the frequency response at the top of the spectrum, the better the impulse response, and therefore the better the perception of transients and other micro-details. What's more, the linearity of a loudspeaker's response curve is primarily a function of the balance between three contradictory parameters: lightness, rigidity and damping.

INCREDIBLE ACOUSTIC CHARACTERISTICS
To date, only one material has made it possible to take a decisive step forward: beryllium. For domes of identical mass, Beryllium is 7 times stiffer than titanium or aluminum, materials which offer the same rigidity for equivalent mass. Sound also travels 3 times faster than in titanium and 2.5 times faster than in aluminum. All in all, the frequency response curve, acoustic transparency and impulse response of the Béryllium inverted dome tweeter are perfect, guaranteeing total control of the work to be done.
