is one of the drivers, made in the 1970's and looks like new. The
driver is the Tannoy HPD315A which is a 12" Dual Concentric, the
Tweeter is mounted down the throat of the Bass cone, behind the dust
cap. I also modelled the driver using CAD software and cut off the front
to calculate the volume intruding into the cabinet, this being
2.068 L |
