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 C150m 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 C150m 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 C150m speakers,
conventional speakers sound a bit bland and lifeless. You may also discover
yourself hearing details at even modest levels on the Sage C150m 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 everenlarging 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 C150m 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 C150m
**
The Wisdom Audio Sage C150m on-wall speaker is a substantial piece of
equipment. Please exercise caution when unpacking your C150m to ensure that
you do not strain yourself from its (perhaps unexpected) weight.
CAUTION: Do not attempt to lift your C150m while bending or twisting from the
waist. Use your legs for lifting, not your back. Always stand as straight as
possible and keep the C150m 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 C150m, 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 C150m the planar magnetic (HF) drivers should be placed as follows:
Mounting the C150m on the Wall
The mounting bracket that mounts to the wall is shipped attached to the back
of the loudspeaker. It is removed by pulling “down” on it relative to the end
of the speaker that will be “up” when installed on the wall. (Note that for
horizontal center channel speakers, this means the bracket is pulled across
the narrow dimension of the speaker.) It is recommended to place a screw into
every open mounting hole so to avoid the bracket possibility resonating once
the speaker is mounted to the wall.
Please note that this guide assumes the wall surface is flat. If not, shims
must be applied to the rear of the mounting bracket so that the mounting
bracket is uniformly secured to the wall and flat (not distorted). The
mounting steps are as follows:
-
Locate the area with the two sets of high- and low-pass speaker cables coming out of the wall.
-
The inside face of the bracket assembly has arrows stamped into it indicating which direction must be “up” when it is mounted on the wall. Align the center screw hole in the mounting bracket next to the speaker cables and attach somewhat loosely using a dry-wall screw (or similar), so you can adjust the bracket for plumb.
-
Using a bubble level to ensure that the mounting bracket is plumb, mark screw holes for EZ-Toggle screws in end clips, using the bracket itself as your template. You can use any opposing (diagonal) set of holes for mounting of the two EZ-Toggle screws in each end clip.
-
Rotate the bracket out of the way and install two of the supplied EZ-Toggle screws in each mounting bracket end clip as follows:
a. Using a #2 Phillips bit in your cordless drill, spin the E-Z Toggle Anchor into the drywall until the head of the anchor is seated flush and the arrows on the head of the anchor point up and down. Repeat this process for each anchor location.
b. To “set” the clamp behind the drywall, place the mounting screw into the anchor and push or tap firmly until approximately 1″ (2.5 cm) of screw is protruding (do not rotate). Then remove the screw. Repeat for each anchor location.
c. Rotate the mounting bracket back over the E-Z Toggles, insert the screw and continue to turn until fastened tightly. The screw stops when the toggle bar secures itself against the opposite side of the drywall (inside the wall). Repeat for each anchor location. -
Install screws suitable for the specific wall material (e.g., sheetrock, brick, concrete, etc.) in all the remaining holes in the mounting bracket to ensure secure attachment to wall and avoid any resonance from mounting bracket. Snug down the center screw as well.
-
Using assistance, while holding the speaker away from the wall, connect both high- and low-pass speaker cables to the rear mounted connectors. Pay close attention to connect the correct wires (high- and low-pass) to their respective speaker connectors while attending to proper polarity.
-
Fix the speaker into the mounting bracket end clips and press down until you hear the speaker lock into the mounting bracket clips. When properly in place, it will snap into position and remain held quite firmly.
-
Install the security set screw in the end cap, snugging down to the mounting clip with the supplied Allen driver. This setscrew prevents the speaker from coming loose by eliminating the vertical movement required to free the speaker from the bracket.
If you need to remove the speaker from the bracket for any reason, first
remove the security screw using the supplied Allen wrench. A sharp upward rap
with the base of one hand or even a non-marring, dead blow hammer will help
jar it loose. (Make sure the speaker itself is being supported by an assistant
so it does not come free from the wall unexpectedly.)
Important! Do not use the C150m 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 C150m 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 C150m 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 four of the twelve 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 C150m 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 C150m, 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.
