The Voice of God Phenomenon...
This was first reported back in the initial report of Audyssey DSX:
have found that speaker placement and also the time delay and levels
are key to creating a good surround effect, but yet, avoiding this.
is no exact formula, that I can write on the proportion of delay and
speaker level. You need to tweak the settings after Audyssey has done
their calibration, then take out that trusty SPL meter, and adjust.
aim, is to let the surrounds be just heard, not too prominently, and
then avoid having them too close to your ears, or setting the time delay
such that you don't have them feel like a pair of headphones placed
right next to your ears.
Then the height is also key. The
relative difference between the fronts, the sides and rear backs is
important. To allow for a good transition of the sound from front to
back and vice versa, the relative heights mustn't be too far. The Dolby
suggested heights are a good start. And something that can spread sound
will be better, that's why I prefer a dipole / bipole to a monopole for
the sides. If you use a monopole direct radiating design, then you must
allow enough distance for the sound to spread outwards.
Try that and experiment with speaker placement until you get the desired effect.
for those of you who can only place speakers at a certain position, or
are reluctant to change positions and can only use certain heights or
types of speakers, then I guess you will have to compromise on the
I have no financial interest or other interests in any of the items / events I write about.
