The Basics of speaker selection

Speaker distribution area coverage angles

Different speakers will have different angles of coverage horizontally (horizontal X axis) and not necessarily be the same vertically (vertical Y axis). The projection of the speaker and distance covered is referred to as the throw (applicable Z axis). It is important to understand these basic principles in order to calculate the distribution of speakers in a volumetric area. The current consensus amongst acoustic engineers is that the majority of audio & visual installation contractors have little or no understanding of scientific calculation methods in selecting speaker systems and distributing them in an environment effectively.

This often leads to over-quantifying of speaker units, power outputs and speaker throw type; a perfect textbook example of which can be found in many nightclubs in the Orchard district of Singapore. For home usage the same scientific principles can be adopted and utilised, with the inclusion of this simple rule of thumb: always use stereo subwoofers as opposed to mono singular.

Speaker distribution using method using suspended Speaker Array

When dealing with large volumetric spaces where there is ample height allowance, the suspended speaker array system is the best possible choice for the best possible Acoustic Euphony. The entire system can be suspended in this way or split into main speaker system and sub speaker system cabinets.
