Introduction
Congratulations on purchasing your Wisdom Audio system. It incorporates many
design features engineered to give you decades of pleasure and performance.
Many of these design choices are uncommon among loudspeaker manufacturers and
bear some explanation. See the following section entitled “Overview” for more
information.
Our unique driver designs and our emphasis on achieving real-world performance
account for the “system” approach taken. These are not speakers that are
simply connected to speaker wires and promptly forgotten. We recognize that
setting up a Wisdom Audio system can be a bit more involved than connecting a
common set of loudspeakers, which is why we recommend that our systems be
engineered and calibrated by Factory Personnel
Your Sage C225m series loudspeaker is specifically designed to avoid the
compromises inherent in conventional speaker designs. There are no passive
crossover components inside the speaker. Instead, there are direct connections
from the amplifiers to their respective High-Pass and Low-Pass drivers and an
external active crossover is used, such as the ones inside of our Wisdom SA-
DSP (Digital Signal Processing) Amplifiers. It is truly a “system” design, and
not merely a collection of loudspeaker drivers in a box. Please contact us to
learn which products/amplifiers/ surround processors outside of our DSP
Amplifiers will work with our speakers and subwoofers.

Overview
Your Sage C225m loudspeakers take advantage of several 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 performance 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 designs.
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.
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 C225m speakers,
conventional speakers sound a bit bland and lifeless. You may also discover
yourself hearing details at even modest levels on the Sage C225m 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.
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 to “keep up” with the planar magnetic
drivers right up to the crossover frequency.
Our woofers are different because they must be to do their job. Specifically,
we need highly dynamic, uncompressed bass (to keep up with the planar magnetic
drivers) that does not depend on a critical amount of enclosure volume (since
these speakers are mounted in your wall and use the space inside the wall as
their “enclosure”). These two design goals require rather extraordinary
attention to myriad details.
Many speakers include a mid-bass “bump” in their response to give the illusion
of going deeper in the bass than they actually do. Unfortunately, this “bump”
makes blending them seamlessly with a high-quality subwoofer almost
impossible.
All Sage Series speakers have been designed to optimally crossover at 80
Hz, which is the most-common crossover frequency used with subwoofers.
Line Source Speakers
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 Wisdom Sage Series C225m 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.

Unpacking and Installing the C225m
The Wisdom Audio Sage C225m on-wall speaker is a substantial piece of
equipment. Please exercise caution when unpacking your C225m to ensure that
you do not strain yourself from its (perhaps unexpected) weight.
CAUTION: Do not attempt to lift your C225m while bending or twisting from
the waist. Use your legs for lifting, not your back. Always stand as straight
as possible and keep the C225m close to your body to reduce strain on your
back.
The speaker is shipped in a “telescoping” box (three five-sided boxes, one of
which fits snugly inside the other). Gently roll the box over so that its
bottom is facing up.
Then carefully cut the tape along the bottom of the box on all four sides.
Roll the box over again so the bottom is on the floor and lift off the top.
With one person at each end, carefully lift the speaker out of the box and lay
it on a soft surface (carpet or similar). We do not recommend removing the
grille on your new loudspeakers.
The grille is an integral part of the design; moreover, the planar magnetic
film should never be touched, as it is tensioned precisely at the factory. The
grille plays an important protective role as well as an aesthetic one.
After unpacking your C225m, keep all packing materials for future transport.
If you need to ship your speaker, only the original, purpose-designed
shipping carton is acceptable. Any other method of shipping this product
runs a significant risk of damage to the speaker – damage that would not be
covered by the warranty. (If you lose your packaging and need to ship your
speakers, replacement packaging can be purchased from Wisdom Audio.)
Proper Planar Placement
For the C225m the planar magnetic (HF) drivers should always be placed as follows:

The mounting brackets and template are included. Please visit our YouTube
channel and installation video if you need assistance.

Important! Do not use the C225m as a shelf! While its
mounting system is quite rugged, it is designed to securely support the weight
of the speaker itself. Do not place additional objects on it, and do not climb
on it.
Making the C225m Connections
As with any system, you should make changes to the connections only when the
power is turned off to avoid any chance of inadvertently causing a problem
(such as a short-circuit).
Note: The Wisdom Audio C225m is a quint-amplified speaker that requires
five sets of speaker wire to each location rather than the usual two. One pair
of connections is for the planar magnetic module, whereas the woofer module
uses four sets of connections, one each for six of the 24 woofers.
We recommend using heavy-gauge speaker wire, the gauge will vary dependent on
your speaker run length. Please consult an authorized dealer to determine what
gauge would be best for your application.
For the purposes of this manual, we will assume that you have already
connected the approved DSP Amplifiers/Processor with Active Crossovers and PEQ
as per the instructions found in its manual. As such, you should have signal
coming from your source component(s) to a preamp/processor, and then on to the
signal that is split into low-pass and high-pass sections, with the low-pass
section going to one or more Wisdom Audio SA Series amplifiers, and the high-
pass section going to additional SA Series amplifiers, which will drive the
planar magnetic panels.
Connect the outputs of your Wisdom Audio SA-series amplifier to the
appropriate woofer sections, taking care to get both the channel assignments
and the polarity correct. Connect the positive (+) terminals on the SA Series
amplifier to the positive (+) terminals for the woofer on the loudspeaker;
likewise, connect the negative (–) terminals on the amplifier and the speaker,
respectively.
Next, connect the outputs of your chosen amplifier for the midrange/treble to
the Sage C225m planar sections in a similar fashion, taking care with all five
channel assignments and polarity.
Care & Maintenance
To remove dust from the front of your C225m, use a feather duster or a lint-
free soft cloth.
Never attempt to clean the drivers themselves.
Caution!
Do not touch the surface of the planar magnetic drivers, under any
circumstances.
The thin film has been carefully pre-tensioned at the factory; any subsequent
contact can only damage it.
