Ken: Are speaker frequency response curves available?

I've recently purchased an acoustic analysis software package that plots frequency response curves. In attempting to evaluate the accuracy of the microphone-sound card-software combination a knowledgeable member of another forum suggested that I try to compare my measured responses with the manufacturer's published frequency response curves.
I have the following Polk Audio speakers:
SDA-1c
CS400i
f/x500i
CS100
MII3
Is it possible for you to send me copies of the frequency response curves for all of these speakers?
On a related subject, can you tell me how to determine the -3dB limits of a speaker given a frequency response curve? In other words it is 3dB down from the peak level on the curve, or is it +/- 3dB from some "average" SPL value for the speaker, etc.?
Are you aware of any sort of published standard that describes how frequency response curves are supposed to be derived?
Thanks in advance.
