Rigid stands, spiked to the floor, are quite beneficial. One manufacturer
took laser measurements of the cabinet movement of their 5" 2-way. Playing
recorded music at normal listening levels, with the stands not spiked to the
floor but just setting on very thin office carpet, they found that the
speaker cabinet movement was about 10 times as large as the tweeter's
maximum possible excursion. What kind of distortion do you suppose that is
causing?

Spikes... a thing I never really understood. So, the idea of spikes is
to create a firm, rigid connection between the cabinet and the large
rigid mass of the floor? Where there is a carpet, set the cabinet on the
floor rather than floating on the carpet. If there's no carpet would
spikes still be beneficial? and do you have to drive them down into the
wood like nails to get any effect? what if the floor is of stone?

Yes, the point is that the spikes penetrate the carpet and give you nice
solid coupling. It's certainly not the only way to achieve that, of course,
and the audiophiles tend to go overboard with them, but they work.
