need advice on refinishing speakers. Do's & Don'ts

Hello

I have a pair of tower speakers I would like very, very much to refinish. the only thing I don't care for about them is they are 'black'. I'd like very much to have them another color. Even natural wood do... pardon the pun.

they have solid wood veneers, ash or oak, I'm not sure. they are stained black, with a clear coat over that. About ten years old.

Is this a doable project? ...or should I have a pro do it?

I'm thinking chems or sanding, ought to get rid of the clear coating, but the stain is another story entirely. If anyone has done this sortr of thing with a good deal of success, I'd sure appreciate finding out the steps needed to do it.

Many thanks.
