3. SHAPE EQ
The physical shape of the array has a profound impact on its sonic performance. These physical
considerations should be compensated for within the DSP EQ to ensure a smooth frequency
response.
a) A at array using minimum splay angles between
the elements will naturally have a boost in the mid
Physical coupling results in

4. SUB PLACEMENT
Having the subwoofers physically aligned in the
same plane as the array elements is the ideal
scenario. However, this is not always possible.
In situations where the subwoofers and the
array elements cannot be physically aligned, a
DSP delay should be used.
1 ms (milliseconds) delay for every 0.34 m
(@15° C) can get you an acceptable result.
It is highly recommended that further fine-tuning
should be done by using one of the many
industry standard measurement software
systems, reference microphones and soundcards.
