I used MDF and felt. I didnt reinforce it like a stealth shelf though so it bowed

 

[Matt1]

what would you recommend reinforcing it with?

iirc Stealth shelves are reinforced with other strips of MDF layered up. They serve to reinforce and give the shelf its shape at the same time.
I used my original shelf as a template and cut round it with a jig saw. Cut out the speaker holes (remember to cut the holes smaller than the speakers lol!) and then covered it with felt using spray glue.
