Invisible Book Speakers

Step 2 Preparing the Center Books

First, you need to figure out the basic internal layout of your speakers. I decided on a simple rectangular cavity, to make it easier. Make the cavity a little wider than the speaker is, so you have some wiggle room. Draw the design of the speaker cavity on the book that will be in the middle. Clamp the book down, drill a pilot hole in one corner of the cavity, and cut out your design using the jigsaw.
