2.5″ voice coil
20mm Xmax

Aluminum magnet ID shorting ring
Spiral cut CZA VC former with a black Nomex wrap
8″ Nomex spider
Sewn-on leads
Large speaker terminals (will accept 4 AWG)
Cast aluminum basket
Proven and effective VC cooling method (air goes in below the spider, around the coil, and out the pole vent)

First impression: Quite stellar build quality for a driver that can be had for less than $200 retail. It was packaged very well. It will be some time before I can make an enclosure for this, so for now – pics of the driver is all I can offer.
