Gallos? Dues or those little ball ones (Unos?). I'm not sure you want to enclose them, so I'd put them on top and angle them down.

You may also want to look at Focal Cub XLs, but I don't know how well those would get along with your wife. (I.E. not sure they would look good in an entertainment center.)

Are you sure you have those dimensions right? 9" tall?
