You could put a positive spin on the cracks, like:
"The beautiful Palisander Rosa veneer of the LS6 is unparalleled in it's presence, with deep, dark color and an exotic pattern. This hard wood veneer has some micro fissures common with the unique look of this rich wood, and will stand out in your home as not only a spectacular loudspeaker, but a work of art."
I don't feel too slimy writing that, because I have purposefully bought 3 speakers with that veneer because I love it so much, and don't give a hoot about the cracks.
