hey I know how to build one if anyone interested, Althought I havn'y tried it myself yet, various people have and had promising reults.
In short i think by winding a coil with heavy guage wire such as 23 guage and to about 9 ohms then then it should act like the coil in a hi-fi speaker. It would have to be potted with varnish or epoxy as there is alot of force on the coils themselves!! :shock:
then go to runoffgroove.com and build a little gem, this would act as the power amp thingy.
Anyway hope that helps. :twisted:
MMM
