You can make one quite easily, form a 3-sided shell about 1" longer and taller than the CS2. I would suggest something like 3/4" MDF, or even 1" for added strength. The CS2 slopes towards the back of the speaker, so I would suggest adding a 1x1 strip along the bottom of the top panel, to give you some extra lateral strength. Sand it, and paint it, hopefully your TV stand is black... If not then you need to look into a nice plywood.
Home Depot/Lowes will make the cuts for you, you only need a few cuts. When you orient the pieces, make sure the top piece sits on top of the sides, and use wood glue and screws.
