Choosing the best location
When using any QLight™ system, certain room parameters will affect the resultant sound quality
and coverage. For example, any boundary like a wall or floor will lift certain frequencies. If you are
placing the unit in a corner then a lift at the bass end is to be expected and it may sound rather
boomy. This can be compensated for moving the speaker or cutting low frequencies with a
graphic equaliser.

graphic equaliser.
When speakers are flown in free space then boundary effects are minimised. The result is a
smooth frequency response without any boost at odd frequencies, but the bass end may appear
subjectively light. In this case increase the sub-bass level to bring the low end up.

The relationship between sound pressure level and distance is an “inverse square law” so
remember that every time the distance from the sound source is doubled the sound level
decreases by 6dB. For every 3dB increase of speaker output you need a doubling of input power
and you can work out the wattage input needed to give the required SPL levels at various
distances from the loudspeaker(s).
