Sorry for the delay......had family visit from out of province.....bbq's, parties, etc, etc.....anyway here is some info....the DC resistance of the good driver is 6.1 ohms. It is a screw on assy......there are four bolts securing the diaphram to the driver......2 3/8 inches from center to center......looks like the thread width is 1 3/8 inches in diameter.....looks like the diameter of the coil winding in the diaphram is 1 and 3/4 inches......attached are a couple more pics.....
