3. They come with spikes or rubber pads, sound is no different if you use or don't use either.
4. No, drivers are oversees, as most speaker companies, but I can tell you, they are the best I've ever used.

ps: I personally auditioned m60's recently against B&W 703's, Klipsch, NHT, and Paradigm using a variety of AV receivers at a professional recording studio my brother in law owns. Personally, I think overall the my m60's one hands down. just my 2 cents, your mileage may vary..
