Repair for speaker cabinet

I am not someone who does such work, but I think it would help to know more about the specifics of the finish of your speaker (e.g., is it painted or stained wood or some kind of resin, is it a gloss finish or semi-gloss or matte), the extent of the damage (pictures might help), and the level of repair you are hoping to achieve (perfect repair or repair that hides obvious damage for someone not doing close inspection).  A perfect repair might not be possible, and if it is, it could be quite expensive.  A furniture shop that does repair can probably do a decent job.  You might contact KEF because they might help you will the right color of the finish material.

Any furniture guy will know how to make it look better.  It is the perfect, or near perfect repair that would be costly.  That would require refinishing the entire cabinet, not just the point of damage.
