Bass drivers feature Mission DiaDrive system：

Natural midrange quality with superb bass transient impact is provided by a seam-free curvilinear cone formulated from a mixture of soft pulp and acrylic fiber specially designed for midrange clarity and lucidity.

DiaDrive twin cone design：

Backing the curvilinear front cone is a stiff, conical support with increased area of contact with the voice coil for outstanding transient impact.

“comb-tooth trim”：

The surround drive unit and fixing screws are cleverly concealed behind this unique trim design giving a highly technical look to the front face of the speaker.
