[Jay Vaughan]

>- Get a TV,
>- Get an old PA
>- open the TV and diconnect the coils from the PCB (one 4 prong connector
>usually).
>- meter the wires and find which are the two sets of coils (somewhere
>between 4 and 8 ohms normally)
>- Connect the speaker out of your PA to these pairs of coils.
>- apply you signals to the input of your PA, switch on the TV and you're
>done!

this could be one of those DIY projects which, with pictures and a 
"don't do this, do that" style instruction guide, could make quite a 
lot of 'waves' out there on the techno-geek blogsphere .. pun
