Ei noista nettilähteistä aina tiedä. Joku saattanut päätellä, että kyseessä on sama elementti, koska päällisin puolin näyttävät samalta. Voi olla, että ovat modanneet elementtiä urakalla. Esim. laadun tarkkailu ja toleranssit ovat todennäköisesti aivan eri tasolla kuin Eminencen hyllytavarassa.
Esim. Druidien elementti näyttää B102 elementiltä (siis edellisen sukupolven mallilta) ja sen mittaukset näyttävät samalta, mutta Zu on parantanut elementtiä kuten 6moonsin artikkelista on luettavissa:
There's presently just one blemish to Fabio's interior decorator tendencies. It's the pride and joy of Zu, their Eminence Legend B-102 inspired wideband driver. In plain view. I'm told grill options are under development for those too prude to go nekkid. For now, let's inspect the 10-incher a little more closely. Zu doesn't hide the fact that Eminence supplies the cast basket; the iron work; the riveting of the ferrite motor parts; the top plate, magnet, yoke and charging of those. The cones are based on an old Hawely design from the 30s. Hawely paper and Western Electric had a pretty close working relationship back then. Eminence
uses this cone as supplied from their OEM. Zu sprays on a solvent carrier to introduce a new binding agent. "Without this, the cone does not have the structure to support the full bandwidth due to slower internal cone velocities especially when combined with our motor. Which leads to the outline of a few other key design features of the motor. Until recently, Eminence had not been modeling -- or at least not implementing -- any devices in the motor for controlling the dynamic AC behavior of the coil and its relationship to the fixed armature, the magnet assembly. Those drivers that do employ such features as shorting rings are not found in too many of their products and none in their 10" drivers. The Zu driver does utilize diamagnetic materials in its motor to influence and shape the inductive dynamics under power, of the interaction of static field and music (AC) field of the coil. And this is not simply a simple little shorting ring.
"Considerations and design features relative to frequency, the eddy currents formed (the shape of the B fields of the coil relative to frequency and wave form) are also manufactured into our driver. And these features are fully operative and designed to continue to be effective even under extreme SPL demands. Just last week we finally found the thermal and mechanical limits of our Zu260FR/G2 driver. The test found the thermal limit of our system, which reflects how accurate my AC modeling was and how solid the implementation is. It took 2000 watts RMS of metal music program with an LR 2nd order high pass set at 80Hz for 6 sustained hours!" Zu's Sean Casey clearly is into all the less visible aspects of driver design. If you manage to blow up a Zu driver, you're the kind of animal who'd scarf down a 100-oz. steak just to get it for free in the one-hour do-or-die challenge. Plus the tacky plaque on the wall.
