I've got M22's in Boston Cherry, on-wall VP100 and M22's in Black Oak, and sub-woofer in Cinnamon Beech.

If I could re-do it, I'd get them all in Cinnamon Beech. It's a fairly neutral color (colour) that would go well with just about anything. It's a little more brown and a little less red than the on-line color (colour) sample shows.
