Robert, All,

I could not ever forsee a reason to soak a coil in oil, EXCEPT for a 
magnifier driver!  This would reduce the space requirement considerably, 
but would be a messy and expensive project.  It would probably be best 
for a very small system.  If I were doing a portable, table-top maggey, I 
might consider a tanked driver.
