rt600i frequency response graph?
can anybody post a link of a frequency response graph for either the rt600i or the rt35i? I have found 1 for the rt25i but, not for any other rt***i speakers.

Assuming the FR is flat anechoic (which knowing Polk it is), the most important piece of data will be the F3, which is the point in the bass spectrum where the response trails off 3 dB with respect to the rest of the spectrum.
Polk usually lists the FR +/- 3 dB, so the lower number will be the lowest usable frequency for bass.
If you want to approximate the anechoic roll-off rate of the speaker below F3, Polk also provides the overall FR, which you can assume to be the F10 number (i.e., 10 dB down).
Just plot out the FR as essentially a straight line down to near the F3 frequency. Then mark the F3 and the F10 points (per Polk's data), and connect the dots with a line. That will give you F0, F3, and F10 (and presumably anything below F10).
Providing Polk's data is correct, the slope of the line should approximate the anechoic roll-off rate, which should be about 24 dB/octave for a vented speaker."What we do in life echoes in eternity"
