Create a pair of speakers by recycling six old hardback books and a pair of speakers from a broken cd player. They will be unnoticeable on a bookshelf, cost virtually nothing, and sound pretty good.
Step 1: Tools and Material
You will need:
6-8 hard back books, about 1 1/4 inches thick each
2 speakers, 3 inches in diameter
Hot glue gun
2 or more clamps
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.
Step 3: Preparing the Outside Books
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.
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.
