WISDOM SERIES LS3m

Line Source Speakers 

Almost all loudspeakers radiate sound into the room as imperfect “point sources”. This 
means that most of the energy they put into the room expands as an ever-enlarging 
sphere, as though emerging from a single point in space. This results in a multitude of 
reflections from the ceiling and floor that can degrade sound quality.  

 

By contrast, the 

Wisdom Series LS3m 

speakers radiate sound as a “line source”. The 

sound moves into the room as an expanding cylinder, rather than as an expanding 
sphere — as though from a vertical line suspended in space.  

 

Line source speakers provide two significant advantages:  

 

Ceiling and floor reflections are minimized, resulting in greatly reduced 
interference, letting you hear more of the speaker and less of the room. 

 

The sound pressure level (SPL) throughout the room is much more evenly 
distributed, making it much easier to set the “right” volume, no matter where 
the audience is seated.  

To achieve this highly desirable line source behavior, it is essential to have a tall and slim 
driver. (Simply stacking multiple “cone & dome” high frequency drivers does not create 
a proper line source. Instead, it creates a 

series 

of point sources, which end up 

interfering with each other). With Wisdom Audio’s planar magnetic technology, it 
becomes possible to have drivers that are 

extremely 

tall and slim.
