P.D.2: para los que crean puedes escuchar superagudos, olvídense de tweeters de Focal de alñta gama, porque tienen une resonancia por arriba bestial y sonarían como un truño
Te aseguro que no me importa en absoluto, este comentario sin lógica alguna y totalmente gratuito. Independientemente de que el único que ha nombrado alfo de Focal he sido yo y en mi firma hay productos de la marca.
Lo que no entiendo es la inercia, que tienes para en cualquier hilo lanzar un bombardeo de datos, que no ilustran a la mayoría ya que generalmente confunden, a la vez que tu inercia te lleva a menospreciar lo que tiene un precio alto y a ensalzar lo barato, cuando una cosa es el producto y sus prestaciones y otra el precio.

Sound & Vision:
The tweeter is no less inventive. The inverted dome is made of beryllium, which is said to be 2.5 times lighter than titanium and seven times as rigid. Like the woofer, the objective here was to achieve a low resonating frequency and high efficiency, normally incompatible goals that are simultaneously met with a turbine-shaped neodymium magnet that leaves the back of the dome itself unencumbered. The resonance frequency is an unheard of 528Hz, providing a huge safety margin below the tweeter's operating range of 2.2 to 40kHz.
What HI-FI:
This performance isn’t accidental: there’s serious engineering in these speakers. The technical highlight is undoubtedly Focal’s Beryllium inverted dome tweeter (below). Beryllium is two and a half times lighter than titanium and seven times more rigid with the same mass, making it a fine tweeter material.

Beryllium is rarely used in hi-fi because of difficulty in manufacturing caused by its toxic nature. But Focal has put a great deal of effort into overcoming these issues, and ended up with a wonderfully clean and detailed performer.
Unlike many rivals – who buy in drive units from OEM suppliers – Focal designs and makes all its drivers in-house. This allows the company to optimise each unti for the speaker it goes into. This is one of the very best tweeters that money can buy.


Pero seguro que se equivocan, tienen resonancias y mal rendimiento y lo digo yo y me pego unas risas…..No Comment
