I have a Klipsch LaScala center speaker mounted on a wall shelf that I built. The speaker has no shielding. It sits within a 1/4" of the top of a 43"x34" screen RPV (Marantz 54"). The tubes and electronics are in the bottom cabinet, and the speaker fields don't reach them. To find out, I put on a focus pattern of white dots, and slowly rolled the TV under the shelf. No changes. With the speaker on the floor, however, the white dots became colorful blobs as I moved them together. You may not need any shielding. If you do, put a 1/4" steel sheet under the speaker. It won't have to suround the speaker. You're not making a Faraday cage to block electromagnetic radiation, just providing an easier path for the magnetic field to follow where they loop around below the speaker.
