It's been shown since March 204 that Bush did his time properly.
Now, how about the other side - Kerry still has not released all his military records, and there are doubts about his receiving an honorable discharge, as well as not fully serving his time, and that in fact his honorable discharge was retroactively issued in the late 90s...
I am an audiophile (and also a manufacturer of speakers). The magnet is typically fixed to the basket; there is a coil of wire (the voice coil) that is attached to the cone. This is what moves. And the basic level, you have the electromagnet of the voice coil pushing/pulling against the fixed magnet. This is what causes the driver to move in and out.
Plastic magnets would be interesting, in that lighter weight speakers could be built; however, I'd really like to see some BH curves of the plastic magnets, first. You do need quite a bit of flux to make a decently efficient loudspeaker; those little flexible refrigerator magnets are way too weak to make a useful speaker.
