I am running speaker wire before drywall. I have an office, square shape, that I want to later install 5.1 or 7.1 surround for playing certain movies or video games on the computer. I know that the speakers should be placed just above ear height. This would mean my speakers are all located about 4' high if wall mounted. They would need to be placed on shelves, stands, or wall brackets. (definitely not doing recessed speakers in the wall since 2 walls have insulation and it would mess with my vapor barrier install) The other option I am thinking about is running my wires to the corners of the ceiling. I would buy speakers that have triangle mounts that screw into the drywall and then swivel to aim the sound towards my listening height. These speakers would be out of the way, but I wonder if the sound is weird since it's coming from above instead of feeling like it's beside and behind me? I can easily run the wire, but I don't have enough left to run wire for both options. Any input would be awesome. I'm leaning towards running all wires in the attic and having a place for 3 speakers along each side of the office to allow front, side, and rear speakers all spaced equally apart. Otherwise I would do something very similar with the wire ran through the wall roughly 48" high.

  • Any reason not to lay the wires on the floor, perhaps under the carpet?

  • @wallyk I was thinking I was being smart by planning ahead and installing them in the near impossible accessible part of the attic before I insulate and drywall but I realize there is no fullproof method and that the wires would be a chore to locate and utilize properly without having the speakers now to know where to mount and how that works. I did decide if I do run speakers I will set them at ear level and just run wire maybe around the base molding or something and then up stands to the speaker. Thanks for the input.

Placement of speakers for a surround sound system can get very specific if you care about it.

By far the most important speakers are the front 3 (center, left and right). The center channel is the most important for movies because most of the dialog comes from the center speaker. Left/right speakers are more important for music but still used a lot in movies.

Ideally all 3 of those speakers would be at the same height and lined up as close as possible with the height of the screen. That means putting the center speaker directly above or directly below the screen, and the left/right accordingly.

Also, ideally the left and right speakers should be about 30º to the side of the center speaker. The exact distance will depend on the position of the seats.

Rear speakers are used mainly for ambient affects and are not nearly as important. I think ideally they are mounted slightly above ear level and 100º to the side of the center (i.e. more to the side of the listener than behind), but ceiling mounting is probably fine as well.

So as you can see you do not want the speakers "equally spaced", although there may be some benefit to wiring your room that way if you want flexibility about future layout.

A few other things to note:

  • If you are using an AV receiver to process the surround sound, many of the mid- and high-end units include room calibration modes that let you compensate somewhat for oddly-placed speakers.
  • If you are going to be using a computer to play movies, note that getting surround sound out of a computer can be tricky. Even for computers/sound cards that support surround sound, it's not always as easy as it seems like it should be.
