Beryllium　Series
It's your prestige　Qrino brand

It reproduces impression, does to become enjoyed from the essence of music, in order to enjoy the flow of the time in such a music space; the most important part is the speaker.

Among those most as for the part which is located on the center when the diaphragm is, positioning, we spent the conception period of 5 years and the development period of 2 years.As a result, the Qurino brand was born.It is more important thing than new technology and epoch-making conception to stare the technology which is accumulated in past history, in the process which is considered concerning the material of the diaphragm, to pursue essence.　What material of diaphragm of ideal?　We overtook thoroughly.　Concerning tweeter for high pass playback of music, at the same time Young's modulus of the material of the diaphragm and ratio of the material density, in other words numerical value of specific modulus the big material, furthermore, those whose high pass resonance frequency is high are the material of ideal. The result and the atomic number 4 which it groped, ”Beryllium” it selected. Because as for the relative importance, “Beryllium” as for 1.848g/cm2 and Young's modulus it is very high numerical value, as for thickness it is possible to prolong very much thin. In the association, as for the aluminum maximum 0.075mm, as for titanium as for “Beryllium” it is possible to 0.02mm maximum 0.05mm, by comparison with those to make thickness thin.In other words, although being possible, in the metal material, to be hardest, to process thin as for the mass there is an advantage where it can process more lightly than the soft metal material.

As for cone type woofer, high pass threshold frequency is decided weight of the diaphragm and the mass of voice coil, by stiffness of the diaphragm point. ”Qurino” not to be to process simply as woofer,” because it develops, full-range speaker” as high pass threshold frequency is designed in order to become very high.
In order adjusts to the acoustic playback ability of Tweeter, to play music, it is the identical material, “Beryllium” is necessary.
We, with 25mm tweeter, 13cm full-range unit and 20cm woofer (all the resister reproducible) developed unit.　This is the worldwide beginning is “Beryllium” FULL sound system.
Those which are different from the music which past you hear completely.　“Qrino”, offers the music playback space of new dimension to you.

 

　　

Qrino brand
special aluminium-almite series speaker

As for the place where the speaker for Qrino brand new product “special aluminum alumite series” car audio and the speaker for the home are different most, as for one for load it is to be unit sale vis-a-vis the home speaker being the finished product. In the speaker for load, as for the position where the tweeter and the woofer are installed there is the difference depending upon the car, variation occurs even in the efficiency which can be played back with the state of the installation of the woofer. In order to solve these problems, with Qrino standardization is assured to the material of the diaphragm in each unit, the timbre between unit is integrated, the sound which has one bodily sensation is played back. At the time of selecting the material, whether it chooses the material which is effective to the treble, or it chooses the material which is effective to concave sound, selection divides, but with Qrino you adhered to the wide range, the woofer which adjusts the component to high resolution of the tweeter tackled the development of the speaker which the synchronizer is done. This time it becomes commodity introduction to the long-awaited spread price range.

The latest technology is special anodic oxidation processing.
As a concrete formation process, it melts special chemicals (electrolyte) first under circumstance of lack of oxygen of the 5,000~10,000℃, can slip on the based aluminum vibrating membrane surface. This because the speed which can be slipped is faster than speed of sound, power of the particle gluing with the base becomes largely close. As for the aluminum vibrating membrane after the special aluminum alumite young's modulus becomes small, specific modulus increases. And density just increases from 2.7×10 m3 kg/m3 in 2.72×10 m3 kg/m3, barely. Without increasing density excessively, you can call that it is possible to enlarge elasticity, feature of the special aluminum alumite. The latest special alumite, the result of pursuing suitable condition in the vibrating membrane of the speaker, super hardness hard to be a little softer than the alumite (HV700) by the fact that also membrane thickness dilutes, deduced the result whose acoustic quality is good.

 

Model BeT-25 & AaT-25 special tweeter chamber
Aluminum block it starts shaving and they are 1 piece structures. With the attenuation of the tweeter vibration and the decrease of diffracted sound, you can aim the accurate sound which does not have incidental sound.

 

Qrino brand new audio cable will challenge at new world!
You aim toward the highest performance where you do not think of just the accessory, also the tuning part do not think, in audio environment.
Moderate thinness of lead wire, in membrane material high freon adoption.
Soft tin plating which administers the temperature management which is equalized in the copper, Kneading direction plus side and 0 side is change, Pitch adjustment of twist, Type of solder and decision of job temperature, And, the production by the craftsman of first person.
As for everything, loving music, because of the love house which does not stop.
