Book Speakers
On the outside books, you can't just saw strait through. Trace the shape of the cavity from the center book onto the cover of the outside book that will be touching the center book. Saw through the book, except for the outside cover. Then do this for the book on the other side. When all the books are put together, there should be a fully enclosed rectangular cavity inside the stack of 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.
There is still an unbroken layer of thin cardboard between the speaker and the outside. Using a safety pin, or something similar, poke lots of holes in the spine of the books.
Now the speaker needs to be fixed to the books. Start by fixing the speaker to the middle book. I did this with hot glue- lots of it. Be sure not to get the glue on the cone of the speaker.
Cut a thin strip of paper out of one of the book, behind the cavity, for the wires to go out of. Spread a thin layer of glue between the covers of each book. Tightly clamp the books together, and leave them for a few hours.
