If you really do have a huge room to work with pull the speakers away from the wall.
How far apart should wall mounted fron speakers.
Position the speakers away from your walls at a distance that s a multiple of thirds or fifths of the room s dimension in that direction.
There s a zone between 1m and 2 2m that ideally you want to avoid.
Placement for dolby atmos and dts x overhead speakers planning to use overhead speakers for special effects.
Like stand mounted bookshelf speakers floor standing speakers or tower speakers should also be moved two feet away from any boundary or wall.
For example if a room is 20 feet long and 15 feet wide locate the left and right front speakers 4 feet one fifth from the wall behind them and 3 feet out one fifth from the left and right side walls.
Your surround speakers should be spaced about the same distance apart as the front left and right speakers.
Get away from the wall.
This works well for me and i ve had it set up this way for quite some time.
If the speakers are in a wall that s 10 feet from your chair place them no more than 10 feet and no less than 5 feet apart from each other to maintain a good stereo effect.
But every room and system is different so your mileage may vary.
Doing this will ensure that your speaker is working as it was designed and not emphasizing bass frequencies from being found in proximity to a wall.
Place the center channel speaker so that it s at ear level when you re seated.
If your television is wall mounted place the center channel speaker slightly below.
