The cleanest whole home audio and home theatre setups are those with speakers embedded in the walls and ceilings. Here's how to hide your speakers and retain great sound.
The most difficult part of installing a ceiling speaker can be running the wires to the speaker. If you have access to the back of the ceiling through a clear crawlspace or attic, then it's easy. But if there is no crawlspace and access is blocked by insulation it will be much more difficult.
You'll also need a plaster hole cutter or plaster saw to cut a hole in the ceiling and screws to attach the speaker mounting plate to the ceiling. These screws are usually packaged with the ceiling speaker as well as a template to assist in cutting the hole.
