The sinewave generator works with the crossover on my 568.2mm. I can verify the 3dB drop in each speaker individually at 80Hz and when the sub and main speaker are both on the crossover frequency they are at the correct level or 3dB higher than the sub and main fronts individually.

I use the Stereophile CD's (Test CD2) and 1/3rd octave warble tones to get the levels correct and then use the sine sweep on the 568.2 to look for any gross peaks and valleys. Be careful though because its easy to be in a null or peak using sinewaves. You need to move around the room listening area to get a better idea if it really is a gross measurement created by the speaker. Using this method I get very good results and can adjust my sub's parametric equalizer to get a nice smooth response in my room. For the most part the warble tones are the best method to get your bass tuned in.
