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 C225i series loudspeaker are 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 Series C225i 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 Series C225i
speakers, conventional speakers sound a bit bland and lifeless. You may also
discover yourself hearing details at even modest levels on the C225i 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
favorably 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.
The motor and suspension system of these woofers therefore includes all the
critical damping required for optimal operation. (In most speakers, the
woofers depend on the air trapped inside their enclosures as an additional
“spring” to help them behave properly.) Technically, this approach is known as
an “infinite baffle” design. In practice, the volume of air behind the speaker
does not have to be infinite, of course. It just needs to be large enough to
not act like an acoustic “spring”. Recommended and minimum enclosure volumes
for the speaker are listed in the Specifications section and repeated on the
Dimensions page.
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 bass management transition used to integrate with
subwoofer(s).
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 Series C225i 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 C225i
The Wisdom Audio Sage C225i in-wall speaker is a substantial piece of
equipment. Please exercise caution when unpacking your C225i to ensure that
you do not strain yourself from its (perhaps unexpected) weight.
Caution! Do not attempt to lift your C225i while bending or twisting from the
waist. Use your legs for lifting, not your back. Always stand as straight as
possible and keep the C225i close to your body to reduce strain on your back.
There are three major pieces involved in a single C225i loudspeaker:
- the Uni-Grip™ in-wall mounting system
- the high operating pressure bass module
- the planar magnetic midrange/treble modules
Note that the two Uni-Grip™ frames for the C225i are not interchangeable,
due to differences in the pattern of threaded holes used to attach the planar
and woofer speaker modules to the frame of each Uni- Grip™. Pay close
attention to the labeling on each, which indicates “Planar Section, Top” or
“Woofer Section, Top” respectively.
In most cases, the planar magnetic section of the C225i will be inside of the
woofer sections. In addition, the two sections must be within approximately 5″
of each other and should typically flank either side of a stud.
Because of the magnitude of the bass energy of which the C225i is capable, it
is strongly recommended that the walls into which the C225i is installed are
rein- forced and as strong as feasible.
In new construction or remodeling applications, we recommend framing in
dedicated spaces that are between 10–11 inches wide for the woofer sections,
just slightly wider than the 9.52 inches required by the Uni- Grip™ frame. If
the wall is going to be skim-coated with plaster after construction, consider
using ¾” inch MDO plywood or MDF for the wall for superior strength. (This
approach is advantageous for the woofer sections; the reaction mass of the
planar section is extremely low and does not require this level of
reinforcement.)
-
Determine the area for the speaker installation and locate the cutout guide using pushpins to secure it in place. Ensure that the template is plumb using a bubble level or similar. Note: Make certain that there are no studs, plumbing or electrical conduit in the intended area behind the wall before you begin marking and cut- ting!
-
Trace the outer perimeter of the cutout guide with a pencil or a utility knife.
-
Remove the traced section of sheet rock using a keyhole saw, and clear debris from the edge of the hole.
-
Push any insulation to the side.
-
Disassemble bezel/Uni- Grip™ and place the supplied Allen head screws to the side. Place the bezel in the wall cutout and insert the Uni-Grip clamping bar through the opening at an angle, working on one side first. Reinstall the Allen head screws with the supplied 3/32″ drill bit, securing both pieces to each other (sandwiching the wall between them), but do not tighten yet. Repeat on the other side.
-
Using a level, adjust assembly in wall cutout to ensure that the assembly is plumb. Tighten the Allen screws. Do not over torque or strip these screws. The large clamping area of the Uni-Grip system does not require unusually high torque on the screws to be secure.
-
Paint the bezel and grill as necessary, being careful not to plug up the holes in the grille. Note that the speaker modules are not mounted in the bezel and grille assembly at this time. They can be mounted later, after all the paint is dry.
-
Using assistance to hold the speaker modules away from the wall, connect both high and low pass speaker cables to the two connectors at the ends of the back boxes, paying attention to assign the correct band-pass and polarity to their respective speaker connectors.
-
Insert the speaker/back box assembly into the Uni-Grip frame and attach using the supplied Allen head screws and 3/32″ drill bit. Do not over torque or strip these screws.

After unpacking your C225i, keep all packing materials for future transport.
If you need to ship your C225i, only the original, purpose-designed shipping
carton is acceptable. Any other method of shipping this product runs a
significant risk of damage to the C225i – 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 C225i the planar magnetic (HF) drivers should always be placed as
follows:
Making the C225i 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 C225i is a quint-amplified speaker that requires five
sets of speaker wire to each of the locations rather than the usual two. One
pair of connections is for the planar magnetic module, whereas the woofer
modules 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.
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 C225i planar sections in a similar fashion, taking care with all five
channel assignments and polarity.
Care and Maintenance
To remove dust from the front of your C225i, use a feather duster or a lint-
free soft cloth.
To remove stubborn dirt and fingerprints from the grille, we recommend
isopropyl alcohol and a soft cloth. Lightly dampen the cloth with alcohol
first and then clean the grille of the C225i with the cloth. Do not use
excessive amounts of alcohol – there is no need for the cloth to be wet;
merely damp is better. 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.
