Invisible Book Speakers

Step 9 Finishing Touches

Drill a large hole in the back of the books and to the speaker cavity, and paint the inside of the hole with glue. Once it is dry, put the speakers on a bookshelf, plug them into your stereo, and enjoy!

what is this last step for?

[Technochicken]

Painting the inside of the cavity with glue stops the pages from vibrating when the speaker is playing. The hole is to let air pass freely into the chamber.

could you put the wires through the big hole and save yourself a step

[Technochicken]

I suppose you could, but they would probably look better with the wires as I did them.

How loud are these? Is the output pretty good or very muffled?

[Technochicken]

By themselves, they play up to a moderate volume before you get distortion, but the books don't seem to muffle the sound. However, if you want to play them loudly you should definitely pair them with a sub.

I think you meant safety pin instead of clothespin! I don't think a clothespin would make a hole in many things... this is a good idea.. bookshelf speakers for sure. It looks like that spade bit was left out in the rain for awhile. Another good way to drill in books is w/ a hole saw because it doesn't tear the paper as much.

[Technochicken]

You're right about the safety pin. I corrected it. The bit I used was only 3/4 of an inch and I'm not sure they make saw bits that size, but if they do, that would be better.
