Maybe they are from a different supplier and to get them to sound like old drivers they had to push them out.
Its really all just speculation. if they wanted to hop in and explain further, i dont think anyone would mind.
Hmm... I don't know about that. I for one absolutely do not like the feel of the cheese cloth touching against my ears. This looks like it could present that scenario when the foam pads soften up over time.
So I guess now the RS1i has been replaced by the RS1s (or RS1is) ? Is that what they are saying? Or are there two versions now?
Oh and in regards to the soundstage image, its the driver diaphragm surface position thats key. So if they kept the original position of the driver / voice coil... but just pushed out the cheese cloth mesh surface, it may not have that much of an impact on the image/soundstage.
What is with the red goop on the driver magnet? Couldn't they find suitable dampening material in black, so its non-visible? That looks terrible.
The other thing it looks like they have done is increase the cup volume behind the driver, by seating it farther out. If that was one of the intentions, a longer/taller wood cup would have been preferable. Grado modders have been doing this for a while now.
