By contrast, the
Wisdom Series C225i
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.
Because of this shape, the sound (even at high frequencies) is distributed uniformly
across the width of the room from a driver that “looks” only less than an inch wide
acoustically. However, the sound is launched in a much more directional way
vertically. By minimizing early reflections from the ceiling and the floor, the clarity
of the system is greatly enhanced. This is heard in both tremendous musical detail
and in much-improved dialog intelligibility.
