My guees is that there are two spiders - one on each end of the voice coil. This allows for a much tighter gap and better BL for a given motor structure. It probably has long excursion.
The downside to this kind of design is a lot of mass in the Voice coil. This creates an extremely limited bandwidth - OK in a subwoofer, a disaster in anything else.
