I have always felt in the back of my mind that room mics will somewhat collapse my stereo image. Let say you have an xy setup 10 ft from a drum kit. Will this not make the toms more mono than you would like? I love the sound of room mics but it seems to make the drums sound more mono. Even with a spread out pair I find that once i get the snare sounding good/in phase through the spaced pair of overheads it makes my toms sound mono as well. I hope this question makes sense. I also see that a mono room mic is often used. How does this not make the drums sound mono? Thanks everyone.
