Stumbled across this dd in rides gallery

Can someone explain to me whats going on here? What are those magnets, how are they different from the regular stacked magnets, and are they more efficient?

I'm not sure, but I have seen the same type of technology in some of the Hifonics subs.

Sawreh, fixed it

Thats old school... IIRC its mostly for cooling and gains in efficiency

pretty much this. is that a neo motor?

its not a neo magnet. Just a very old DD...

Plenty of companies have used that design before. It has some performance advantages, like cooling. It also has the advantage of being cheaper to manufacture, since those sized magnets are much more common.

No, its not a neo motor. Those are just small stacked ferrite magnets.

Doesn't Focal currently use that design with some of their subs?

 

[audioholic 5,000+ posts]

Focal has for years.

also the diyma 12, also the sub which is ever so dominantly dispayed at the top of car audio forum. (next to your name, notifications, profile and settings)

Bones22 owned one or two of those subs...I thought they looked pretty neat

Why would you suppose we don't see this as often anymore? If it has both advantages in performance while at a cheaper manufacture cost shouldn't it be a popular design for companies?

That's the Focal sub mentioned earlier.

I dont know how effective it is at focusing a magnetic field. And I can only assume the field is weaker, since there is less magnetic material. You could stack higher, but coil height would be a factor as well. perhaps someone like sundownz or splaudio could chime in with more info on this motor type.
