Special Note - This is an end of life product. There're only a few left* with cosmetic blemish(light scratch, slight dent on the honeycomb disk). However, a new version is available in 2016. New version will also be a direct replacement driver w/o the honeycomb design. All the mechanical and electrical specification and performance will be maintained except the cosmetic look: paper cone vs. honeycomb disk. The new driver will be less costly and better improved on the low end performance. Follow us on Twitter for further announcement.

* Call or eMail for the conditions and availability. Some new and/or some cosmetic blemish.
