We have all heard of how expensive it is to build loudspeakers using Beryllium, so what exactly is it good for?
First of all, most loudspeakers used in headphones are made of cone-shaped mylar or paper diaphragm. The cone, of course, is where soundwaves are generated through electro-magnetic vibrations.
Materials used to build diaphragm differs in their mass, stiffness and damping, and the differences in the ratio of these characteristics directly affects the sound quality, pitch, accuracy and responsiveness of the loudspeaker.
Although, it is one of the most expensive materials used to make diaphragms, in terms of stiffness-to-weight ratio, Beryllium is the highest of any known metal. In fact, its stiffness usually raises its resonances to way over 50 kHz, eliminating the need for surface treatments of any kind.
It is precisely this characteristics, which gives Beryllium speakers its unique high responsivenss, and sound clarity.
You must be wondering, what do all these jargons mean to me, as a user?
Simply put, in a market filled with headphones that only focuses on a strong bass output, audio enthusiasts are fed up with mirky and sloppy trebles and mid-tones as a compromise for powerful bass.
Yet, as you will find in any models from Accutone bearing the word "HD" in its name, headphones with Beryllium speakers have excellent accurate and clean sounds. Without sacrificing strong bass performance, even the finest details are all there.
More noticeably is the quickness and responsiveness during transitions in music, as there is little to none "leftover" sound to cloud up the overall audio experience.
But of course, it is very difficult to explain this in writing, so the best way to find out if Beryllium loudspeakers are worth it, is to go try one yourself.
