Eliminating floor and ceiling reflections, Line Source Speakers are especially valuable for large rooms, theatres, or those with architectural challenges including cathedral or coffered ceilings, hard floors, etc. Their singular benefit is heard in any room: you hear more of the speaker and less of the room. Everything is significantly clearer.
So what exactly are Line Source Speakers, and how do they benefit your room?
Understanding The Difference Between a Point Source and a Line Source
How a Point Source Works
When a speaker has a point source, the sound waves expand as a sphere spreading energy in all directions, bouncing off walls and other objects in your environment. As a result, it loses 6 dB per doubling of distance. The further you are from the speakers, the more clarity is lost.
How a Line Source Works
In contrast, a line source loudspeaker produces a wave which expands like a cylinder. The energy stays concentrated within the window of the line source. Unlike point sources, they only lose 3 dB of volume per doubling of distance, which means they have significantly reduced propagation loss.
Advantages of Wisdom Audio
Line Source Loudspeakers
Wisdom Audio’s unique design provides enhanced clarity and smooth consistent coverage as compared to point sources and is a great choice for large spaces or those with architectural challenges (including cathedral or coffered ceilings, hard floors etc).
Controlled Directivity
As sound waves radiate widely in a horizontal direction instead of vertically, this controlled directivity virtually eliminates the harmful effects of floor and ceiling reflections.
In fact, because the sound is concentrated where your ears are, it does not “thin out” nearly as fast and people sitting near the speakers and far away hear pretty much the same volume.
Uniform Sound Pressure Level
Wisdom Audio line sources are able to deliver sound into space more efficiently, and the desired intelligibility and volume level are easily achieved with less strain from the electronics in the system.
This is a big advantage when entertaining since even in a large room you can set a single volume that supports conversation for all… even those close to the speakers.
