Theater speaker placement.

A customer of ours sent us a great web application that helps with placement in a theater set up.

Directly from Dolby Labs.

Placing the inwall/ceiling speakers into a theater setup is never perfect. You always have to compromise because you want to hide the speakers inside the walls or ceiling.

It's not that bad. It's probably at worst 90% from perfect sound.

The theater receivers available today do an AMAZING job of correcting for those placement challenges with their sound setup functions. They actually time align the sounds before they hit the speakers, giving great imaging in the correct places in your rooms.
