Thanks for the replies. Yes, these are Natural Cherry. I bought these from an authorized dealer and they have consecutive serial numbers. Just wanted to get some opinions on this. I guess it’s not really a big deal. I noticed the difference in color when I was moving them into place. The darker veneer on the back is not a big difference from the rest of the speaker cabinet, but you can definitely tell it is a little darker Cherry color if you really look at it. Guess I shouldn’t worry about it and enjoy the sound. 😄
