Introduction
Congratulations on purchasing your Wisdom Audio loudspeakers. They in-
corporate many design features designed 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.
While we expect your local Wisdom Audio dealer to take care of the setup and
calibration of the system, we still recommend that you at least briefly review
this and your other manuals to better understand your system’s full
capabilities.
You do not have to do anything to register your warranty for your Wisdom Audio
products. (Isn’t that a pleasant surprise?)
In the unlikely event that your loudspeakers ever require service, please
contact the dealer from whom you purchased them. Between their records and
ours, you should be all set.
However, please keep your sales receipt in a safe and easily found place.
Should you move or lose touch with your original dealer, it will serve as your
proof of purchase for warranty purposes.
Overview
Your Insight Series P2m 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 Insight Series P2m
speakers, conventional speakers sound a bit bland and lifeless. You may also
discover yourself hearing details at even modest levels on the P2m 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,
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 in order 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 Insight Series speakers have been designed optimally at the response to 80
Hz, which is the most-common crossover frequency used with subwoofers.
Unpacking and Installing the P2m
Your new Wisdom Audio Insight Series P2m on-wall loudspeaker is relatively
compact, but surprisingly heavy compared to most on-wall speakers. Please
exercise caution when unpacking your P2m to ensure that you do not strain
yourself from its weight. CAUTION: Do not attempt to lift your P2m module
while bending or twisting from the waist. Use your legs for lifting, not your
back. Always stand as straight as possible and keep the P2m close to your body
to reduce strain on your back.
Carefully lift the speaker out of the box and lay it on a soft surface (carpet
or similar). Carefully remove the magnetic grille by gripping the edge of one
of the short sides of the grille and lifting it off the speaker from one side
to the other to avoid damaging the grille. Lay the grille face up on a flat
surface.
Unwrap the cloth wrapping from the speaker that prevents the finish from being
scratched by any of the packagings. Your P2m is now ready to be installed.
After unpacking your P2m, 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 P2m on the Wall
The mounting bracket is shipped in a small plastic bag inside the packaging of
the loudspeaker. Included are drywall anchors, screws, and mounting brackets.
All Insight On-Wall loudspeakers ship from the factory oriented for vertical
mounting position. Pay proper attention to the intended orientation of the
loudspeaker.
When mounting horizontally, be sure to follow step 7: Planar Magnetic
Driver Orientation and step 8: Mounting Bracket Orientation. When mounting
vertically, skip these steps and proceed to step 9.
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 speaker wire coming out of the wall.
-
Using the installation template included in the box, tack or tape the template to the wall in the location where the speaker is to be installed.
-
For drywall anchors, use a 5/16″ (8 mm) bit to drill 1.5″ (40 mm) deep pilot holes in each of the six marked locations. For installations without the drywall anchors use a 1/8″ (3 mm) bit to drill pilot holes in each of the six marked locations.
-
Remove the template from the wall.
-
For installations using the drywall anchors, insert them into the wall until the head is seated flush by lightly tapping them into place with a hammer.
-
If the speaker is to be mounted horizontally, proceed to steps 7 and 8.
Otherwise, skip steps 7-8 and proceed to step 9. -
Planar Magnetic Driver Orientation: The Planar Magnetic Driver in your new P4m is orientation specific. There are two orientation-marking lines on either side of the Planar Magnetic Driver’s faceplate. These two lines must always be vertical, regardless of the speakers mounting orientation. Use extreme caution during this procedure to prevent scratching the high gloss surface of the speaker cabinet.
a) Lay the speaker with the front face down on a soft surface (carpet or similar) and use the foam from the packaging can be used to prevent the speaker from being scratched.
b) Use a metric #3 Hex key or Allen wrench to remove the four screws holding the Planar Magnetic Driver in place.
c) Using a Mini Pick or Hook tool, insert the tip into one of the screw holes and turn it slightly to catch the bottom edge of the front plate of the Planar Magnetic Driver.
d) Gently raise the Planar Magnetic Driver from the speaker cabinet until it can be removed by hand. Use care not to pull the driver too far from the cabinet and stress the attaching speaker wire.
e) Rotate the Planar Magnetic Driver 90° so that the orientation lines point out from the speaker, away from the woofers.
f) Re-insert the four screws and tighten the Planar Magnetic Driver into place. -
Mounting Bracket Orientation: Use extreme caution during this procedure to prevent scratching the high gloss surface of the speaker cabinet.
a) Lay the speaker with the front face down on a soft surface (carpet or similar) and use the foam from the packaging can be used to prevent the speaker from being scratched.
b) Using a #2 Phillips screwdriver remove the mounting brackets from the speaker.
c) There is one mounting bracket screw installed in the speaker directly below each bracket. Remove the screw.
d) Rotate the mounting bracket 90° towards the now upwards facing side of the speaker and re-install the bracket.
e) Ensure the additional screw is inserted back into the vacant hole where the mounting bracket was factory installed. -
Using assistance, while holding the speaker back from the wall, connect the speaker cables to the rear spring terminals, while attending to proper polarity.
-
Align the speaker on the wall, just above the mounting brackets, and lower it down until you feel the speaker’s weight being taken by the bracket. Unlike Sage On-Wall speakers the speaker will not snap into position.
-
Carefully align and replace the magnetic grille onto the speaker. 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. If you need to remove the speaker from the bracket for any reason, simply support the speaker and raise it upwards until it comes free of the wall bracket.
Making the P2m 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).
One set of speaker wires is required for each P2m loudspeaker.
We recommend using heavy-gauge speaker wire, particularly when the
installation forces you to use longer wires than you might otherwise. A good
rule of thumb is to keep the “loop resistance” below 0.07 ohms.
The loop resistance can be easily measured with an inexpensive volt-ohm meter.
Simply twist the two conductors at one end of the cable together, and then
measure the DC resistance across the two conductors at the other end of the
speaker wire. Doing this measures the total resistance going down one side and
back the other, hence the term “loop resistance”. If this figure is at or
below 0.07 ohms, you are in good shape.
The P2m and Subwoofers
All Insight Series loudspeakers are optimized for use with subwoofers, with a
crossover of 80 Hz. (This is the most common frequency below which subwoofers
are used.)
When properly installed on the wall, your P2m has inherently at the response
to 80 Hz, without the common “bass bump” that characterizes most in-wall
speakers and is placed there to yield the impression of “more bass” than there
really is. This makes it easy to blend seamlessly with a high-quality
subwoofer such as one of Wisdom Audio’s Regenerative Transmission Line™ (RTL™)
subwoofers.
You should setup your surround processor speaker bass management to “Small”
and or with an 80 Hz crossover to maximize the speaker’s output. Doing so
ensures that all content below 80 Hz is directed to the subwoofer(s) for
reproduction.
Care and Maintenance
To remove dust from the front of your P2m, 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 P2m 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.
