Description
Your Insight Series P6i loudspeakers take advantage of sev-
eral critical technologies to deliver a level of performance
that has never been available in a loudspeaker that intruded
so modestly on your living space. In fact, this level of perfor-
mance has rarely been attained, regardless of the space and
budget at one’s disposal.
Since several of these technologies cannot readily be found
elsewhere, we will take the time to describe them in more
detail than would be necessary for more conventional de-
signs.
Planar magnetic drivers Our planar magnetic drivers use an advanced, thin film
membrane to move the air. This film can respond instantly
to the smallest detail in the signal. It has vastly less inertia
than traditional “cone & dome” drivers, so the signal is never
blurred in any way.
The motive force is pro-
vided by a “voice coil”
that is printed on the
film, which is suspended
in a strong magnetic
field provided by pow-
erful magnets behind
and in front of the film.
The ratio of available force to the moving mass is huge, which means that the
diaphragm does exactly what it is told: nothing more, nothing less.
Free from compression 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 flat 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 con-
ventional 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 Insight Series P6i
speakers, conventional speakers sound a bit bland and lifeless. You may also
discover yourself hearing details at even modest levels on the P6i that were pre-
viously inaudible even at loud volumes on more conventional speakers.
More reliable The “voice coil” in the planar magnetic driver is spread out over a large, flat area
that is exposed to the open air. As such, when a huge transient comes along,
