Because the conductor of a planar magnetic driver is essentially a long, thin wire, it
presents a purely resistive load to the amplifier. This is comparable to the simple test
loads that amplifier 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.
Authoritative, deep bass requires that you move a lot of air. We have chosen to use
dynamic woofers for the bass because they can provide excellent performance at
lower frequencies.
In order to get comparable bass performance from a planar magnetic design, you
would need to have a huge speaker that would be impractical in most domestic living
spaces. It simply makes more sense to use the best transducer technology in each
area of the reproduced spectrum.
One of Wisdom Audio’s strengths is in seamlessly
blending these technologies
—
particularly important given the high standards set by
our planar magnetic drivers.
Of course, the dynamic woofers themselves must be rather extraordinary in order to
“keep up”
with the planar magnetic drivers right up to the crossover frequency.
All Sage Cinema Series speakers have been designed for optimal at response to 80
Hz, which is the most-common crossover frequency used with subwoofers.
Designed to Match the Line Source Speakers
–
A Completely New Configuration
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 Cinema Series Line2, Line3 and Line4 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.
