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.
Floor standing speakers distance from wall.
This listening position equidistant from the speakers and slightly farther from each speaker than the speakers are from each other is called the sweet spot.
Turn the speakers so the the sounds reach behind your ears.
If you really do have a huge room to work with pull the speakers away from the wall.
Time aligned speakers tend to require a certain distance for the drivers to coalesce into a properly integrated combined soundfield.
If d fwall is the distance to the wall behind your speaker you can calculate the quarter wavelength cancellation frequency using this formula.
Position yourself nearer the speakers not 60 60 60 but 90 45 45.
The speakers and listener should form a triangle.
This influences something called standing waves.
So a shallow triangle.
The stereo sound appear virtually more separated and spacious.
I sit 7 away from the plane of the single driver speakers with a bit over 9 between speakers.
It s vital that the listener sit exactly between the two loudspeakers and at the same distance from each.
Position the speakers so that the distance between the front wall is 1 3 to 1 5 the length of the room.
There s a zone between 1m and 2 2m that ideally you want to avoid.
Firstly place your speakers right up against the wall flat out not toed in and the appropriate distance apart usually 1 5 2 5m depending on relative listening position and aesthetics.
Get away from the wall.
Keep the speakers on the floor little away from the wall.
At low frequencies the performance is determined by the overall dimensions of the room.
Like stand mounted bookshelf speakers floor standing speakers or tower speakers should also be moved two feet away from any boundary or wall.
With the speakers in this position listen to a relatively detailed familiar 30 second part of a track the more familiar you are with it the better.
Any back ported speaker with a port diameter of 2 for example will work just fine placed up to a wall as long as there is 2 of space behind the port.
Height width and depth.
Doing so will prevent the speakers from creating standing waves and exciting room resonances the peak and valley null nodes when reflected frequency responses are in or out of phase with each other.
And oh look that just happens to be the minimum distance to the wall recommended by genelec for their back ported speakers what a coincidence.
