Front speaker heights
One of the most important parameters for the front speakers in a
home theater system is their height. Refer to the following illustration
for an example of ideal speaker height placement.
In an ideal arrangement, all three speakers are aligned on the same
horizontal plane in relation to the viewing screen. This establishes a
firm “audio image” height when special audio effects are panned from
one side to the other, such as a speeding car moving across the
screen.
A large “audio image” discontinuity (mismatch) occurs when the
heights of the front speakers vary, as illustrated below. This uneven
speaker arrangement makes the “audio image” of a moving object
sound unnatural due to shifts in the audio image height.
