You may want to try colored lemon oil -- this product does not remove the scrath, just covers with colored oil to make it less visible.
The MFR may have some suggestions or products available for this purpose.
There are other products such as colored fillers that may work as well.
Since you are asking others for advise, I would assume that wood finish repair is not your specialty. With that in mind, I would avoid the use of abrasives at all costs. Some speaker manufacturers use tinted lacquer for a coating, and as you sand, you may remove layers of color, hence changing the look of the entire area that has been sanded. If you choose to use abrasives, I would use 600 grit wet sand or higher. The all advise in the above post is also good, with the exception that I do not agree with 220 grit -- to rough in my opinion.
Keep in mind you are probably working with 1/16 or less of veneer thickness. You remove too much you will have MDF visible...
Good Luck
