inertia than traditional “cone & dome” drivers, so the signal is never blurred in any
way.
One of the most remarkable things about the sound of well-designed planar
magnetic speakers is their lack of thermal or dynamic compression. There are
several reasons for this:
•
The lightweight diaphragm responds quickly to even the smallest signals yet
is robust enough to handle a great deal of power.
•
The voice coil is laid out at and is exposed to the air on both sides; the large
resulting surface area dissipates heat extremely quickly and efficiently.
•
Since heat does not build up in the voice coil (as it does in conventional
dynamic drivers), the load seen by the amplifier does not change at high
power levels.
When you become accustomed to the sound of your new
Sage P20m
speakers,
conventional speakers sound a bit bland and lifeless. You may also discover
yourself hearing details at even modest levels on the
Sage P20m
that were
previously inaudible even at loud volumes on more conventional speakers.
The “voice coil” in the planar magnetic driver is spread out over a large, at area
that is exposed to the open air. As such, when a huge transient comes along,
any
heat that is generated is immediately dissipated. This compares quite favor- ably to
other designs in which the voice coil is buried inside a massive piece of metal,
where the heat has effectively no place to go.
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.
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.
