Subject: Speaker Like Sensor ?

Hello instrument folks,

Is it possible to get a speaker company to
build the mechanism like a speaker
without a cone that would be like
500 to 10K OHMS or more instead of
the typical 8 ohms ?

I think it may be the best of all sensors
for a velocity type anything geophone ??

Comments ?

It seems to me if you are going to
make the coil a part of the mechanism
you need that special delicate speaker
wire that is braided with cloth 
so that the springy nature of the wire
will not be there to affect your results?
