Take a picture of the gouge, use good lighting and a camera with decent close focus (macro) ability and post it online somewhere. I can tell you if it's repairable or not.
As long as the gouge isn't through the veneer, it can be fixed, thought not a simple job. The speakers would have to be stripped to bare cabinets, the gouged panel sanded until the gouge is gone and all other panels sanded to remove old finish, and then new finish sprayed. And to get a grain filled finish usually requires a total of 10-20 coats approx. depending on veneer species. And honestly you'd want to do both speakers or else the finish wouldn't match exactly.
Anybody is going to charge at least $500 to do all that, unless you have a buddy who knows what he's doing :)
