Invisible Book Speakers

Step 4 Preparing the Inside of the Books

Near the spine of the books, where you cut out, there will still be a fairly thick layer of paper. This paper will block the sound if not removed. To remove it, fold the covers of the book out and together, and fasten them there so they do not get in the way. Clamp the book down, and, using the jigsaw, cut most of the way to the binding, but not all the way through. Cut a slit in the paper between the pages and the cover with a box cutter, and also with the box cutter, finish cutting out the layer of paper at the front of the speaker cavity.
