Fenomen magnetic interesant .

[felixx]

Vad ca ti s-a pus pata pe neodimiu....cauta sa citesti cate ceva despre permendur/piese polare/prelucrarea lui (vezi Feastrex loudspeaker) si electromagnet (cum,cat,la ce tensiuni de alimentare si in ce mod afecteaza sau diminueaza fluxul in intrefier si deasemenea cum se percepe sunetul in urma modificarii acestuia).

Teoria ca teoria insa cu punerea in practica e mai greu.

 

Ma intreb oare de ce difuzorul din Tannoy Westminster/seria Prestige (care este o referinta) nu a adoptat solutia spusa de tine....?

Oare de ce Westlake audio sau TAD ori JBL K2 nu foloseste neodimiu in referintele lor?

Aici ai o lista cu ce inseamna Westlake pentru mastering si nu numai:

Cele de mai sus sunt doar o foarte mica parte din cei care sunt REFERINTE in incinte acustice "comerciale";asta ca sa nu ne gandim mai departe la GOTO,Ale,Vitavox si alte "ciudatenii" pentru "cunoscatorii" si cei care isi dau cu parerea despre cum/cat si de ce nu ar trebui sa fie,etc.....

 

...pentru detalii tehnice contacteaza direct producatorii sau detinatorii de astfel de sisteme.

Legat de magnetii alnico :In this genre of drivers, Alnico—a contraction of aluminum, nickel and cobalt—enjoys a near mythical reputation. Because Voxativ uses an Alnico motor in one of their drivers but not the top offerings, I asked why. "I have repaired and rebuilt thousands of drive units over the last ten years. I always insert a special probe in their voice coils to measure remaining field strength in the gap. With Alnico it's invariably well below the original specification. Alnico only maintains magnetization wedged between steel plates. Fixing an Alnico core such that it cannot slip by impacts in transit or over time by even 0.1mm is critical. Otherwise field strength is seriously compromised. At the physical magnet sizes required for 2+ Gauss motors, this gets more challenging than one might think.
