I did find a similar post, but not with this approach .. what do you think?
Today I did some experiments, don't know if this is done before .. but I'll share my idea for discussion. Recording vocals with speakers on.
1) Setup the mic and a gain setting for the song (or part of the song)
2) Set a comfortable level on 1 speaker
3) Be very quiet and do a silent pass, record the spill in the mic
4) Don't change any levels on the pre/speaker, don't change mic position ..
5) Record your vocals
6) Buss the silent pass (flip the polarity) with the recorded track
7) If desired, bounce the vocal buss for easier editing
I found out this worked pretty good .. and got a very clean vocal to compress/eq afterwards ..it doesn't eliminate the spill completly .. but it did give a serious and very workable reduction.
NOTE .. when you change mic position/pre-amp gain/speaker level .. re-record the silent mic-spill pass for that part. That's the only trade off I guess.
Worth trying, or done before?

Reason: added examples
I've done this to good effect with recording small choirs to backing tracks. A lot easier than getting 12 headphones running.
I don't even bother with the null pass until the end of the session, that way any adjustments I make in the session will null.
You can't record with any compression as it will mess up the cancellation with the null pass.
I've also recorded small groups by placing a speaker to the side of a figure 8 mic. I get the speaker close to the mic, 12"-18". You can squeeze in up to 6 singers by using both sides of the fig 8. The isolation is pretty good even without a null pass.
It's important with both these techniques to have a music bed with similar balance to the finished mix and doesn't contain any click/guide tracks that you don't want to hear in the finished mix.
