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 P38m 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. [email protected]

Overview

Your Sage P38m 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

SAGE P38m WISDOMAUDIO.COM

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 P38m speakers,

conventional speakers sound a bit bland and lifeless. You may also discover

yourself hearing details at even modest levels on the Sage P38m 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.

SAGE P38m WISDOMAUDIO.COM

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.

Unpacking and Installing the P38m

The Wisdom Audio Sage P38m on-wall speaker is a substantial piece of

equipment. Please exercise caution when unpacking your P38m to ensure that you

do not strain yourself from its (perhaps unexpected) weight.

CAUTION: Do not attempt to lift your P38m while bending or twisting from the

waist. Use your legs for lifting, not your back. Always stand as straight as possible

and keep the P38m close to your body to reduce strain on your back.

The speaker is shipped in a “telescoping” box (two 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).

SAGE P38m WISDOMAUDIO.COM

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 P38m, 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.)

Mounting the P38m 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:

1. Locate the area with the two sets of high- and low-pass speaker cables

coming out of the wall.

2. 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

SAGE P38m WISDOMAUDIO.COM

cables and attach somewhat loosely using a dry-wall screw (or similar),

so you can adjust the bracket for plumb.

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.

8. 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

SAGE P38m WISDOMAUDIO.COM

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 P38m 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 P38m 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).

Two sets of speaker wires are required for each Sage P38m loudspeaker: one for

the woofer (low pass) section, and a separate one for the planar magnetic (high

pass) section that handles the midrange and treble.

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 P38m planar sections in a similar fashion, taking care with both channel

assignments and polarity.
