The SD12 is the first driver in CSS's new SubDuction Series.

The primary goal for this driver is to have great sound quality with the ability to provide a firm foundation of bass for your entire system. With 19.5mm of linear Xmax it has the ability to keep up with the rest of your system at great SPL levels as well!

This driver has many great features typically not seen in drivers at this price point either!
