The excellent heat dissipation of these drivers makes them remarkably reliable.
Planar magnetic speakers can handle a great deal of power without undue stress
or audible strain. In fact, for a given size, they can handle
many times the power
of a traditional dynamic driver.
Easy on amplifiers
Because the conductor is essentially a long, thin wire, it presents a purely resis-
tive load to the amplifier. This is comparable to the simple test loads that ampli-
fier companies use when measuring their amplifiers to show how terrific they
are. As such, you can be assured that your amplifiers will sound and work their
best.
Line source behavior
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 Sage L100i 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 re-
duced 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.
