The blurb technical said 300W RMS handling for this 12 inch speaker.
Now it is blown and I've opened up
2 layers of 90 turns , so 180 turns of .16mm or 6.3 mil/thou diameter wire
on 64 mm diameter former.
300 Watt ?

What make and model speaker is it? what`s failed? is the voice coil
burnt? What was diving it when it blew? and what signal content?
