I think that Mike and Peter are spot on, but I also think that Randy makes a valid point.
I think it would be very time consuming to photograph the blemishes. It's one thing to take a photograph of an entire product, but it's another to adequately capture a small scratch or nick (as an example). There's all kinds of variables like lighting, the angle at which you're taking the photograph etc., that don't come into play to the same extent as standing back a couple feet and taking a picture of an entire speaker. I wouldn't be surprised if it would take a handful of tries to capture a picture that would show a blemish.
Just my 2¢.
I dream of finding a really hot girlfriend that's mute!
