Whats a good freq to measure baseline SPL when calibrating a sub?

So I finally got my REL T/5i sub and will be calibrating it this weekend.  I have an SPL meter and a test tones CD.  I know the first step is to pick a test tone to set the baseline SPL from my monitors which I will use to compare the  low freq response of the sub.  Can someone please recommend a good starting freq?

How about all of them, aka pink noise? Cheers,

Thank you for the reply.  I thought it was better to use specific freq test tones to set up the sub???

One more idea:

If you can generate both pink noise and white noise, sweep both. IMO, pink noise will give you better octave to octave balance while white noise will be more helpful for optimizing the hand-off from subwoofer to main speaker.
