Pre-wiring Home Theater System

I've never been to big into the A/V scene. I'm the type of guy when it comes to audio visual equipment that i want it to be simple, fast and reasonable quality.

So when the opportunity came to pre-wire my new home. I decided i would, as it would allow to 'future' proof the theater room and provide a clean look when the speakers are installed.

I opted for a 5.1 pre-wire as i believed that with the technology at the time, 5.1 Channels would be sufficient. Then seemingly out of the blue, Dolby Atmos has come.

Now with these new technology, you can have 5.1.2 and greater systems. essentially the new audio standard allows for a new sound experience adding in elevation to provide extra depth of sound.
Generally i wouldn't be to phase, but for some reason this new sound type really has me intrigued.

It will be very difficult to retrofit ceiling speakers (although not impossible) into our down stairs theater room. As long as i can get between the floor joists, i should be able to pass a cable along the plaster line and somehow feed it down the wall.

Either way, if your planning on pre-wiring your home, ensure to include at least 2 extra forward or rear ceiling cable runs to future proof for the next decade.
