Introduction
Congratulations on purchasing your Wisdom Audio loudspeakers. They in­corporate 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 brie y review this and your other manuals in order 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 Sage Cinema Series Point 2 V2 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 Cinema Series Point 2 V2 speakers, conventional speakers sound a bit bland and lifeless. You may also discover yourself hearing details at even modest levels on the Point 2 V2 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.

Overview (continued)
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.
In order 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 in order 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 Sage Cinema Series speakers have been designed for optimally at response to 80 Hz, which is the most-common crossover frequency used with subwoofers.

Unpacking & Installing the Point 2 V2
The Wisdom Audio Sage Cinema Point 2 V2 speaker is a substantial piece of equipment. Please exercise caution when unpacking your Point 2 V2 to ensure that you do not strain yourself from its (perhaps unexpected) weight.
CAUTION:
Do not attempt!to!lift!your!Point!2!V2!modules!while!bending!or!twisting!from!the! waist.!!Use!your!legs!for!lifting,!not!your!back.!!!
Always stand as straight as possible and keep the Point 2 V2 close to your body to reduce strain on your back.
We do not recommend removing the grille on your new loudspeakers except temporarily, if you need to re-orient the planar magnetic module. 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.
After unpacking your Point 2 V2, keep all packing materials for future transport. In the event that you need to ship your Point 2 V2, only the original, purpose-de­signed shipping carton is acceptable. Any other method of shipping this product runs a significant risk of damage to the Point 2 V2 —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 Point 2 V2
The Sage Cinema Point 2 V2 is designed to take advantage of hidden installations in which it will be located either behind an acoustically transparent screen or behind stretched fabric. It may be mounted either as an in-wall or as an on-wall speaker, or in/on the ceiling.
The flexible mounting brackets provided with the Point 2 V2 allow dozens of possible mounting options, depending on what you choose to use as your reference surface. The beveled back edges of the speakers also may be used as a wire chase in situations where space is tight.
Controlled Directivity
In addition, the Point 2 V2 has controlled directivity that allows the installer to focus the sound where it needs to go.
As shipped from Wisdom Audio, the planar magnetic driver (PMD) is oriented such that (when the speaker is located upright) the greatest dispersion is in the horizontal plane. It is designed to have somewhat limited vertical dispersion so as to minimize ceiling and floor reflections that would color the sound.
However, if the design calls for horizontal mounting instead, the PMD can easily be rotated 90° to maintain the optimum dispersion at higher frequencies.

In addition to vertical and horizontal mounting of the PMD, you can also angle it in three additional directions.
By removing the plate in which the PMD is mounted, you expose a new surface to which the PMD may be mounted at a 22.5° angle. This angled surface may also be rotated in 90° increments.
For example, think of a situation in which the Point 2 V2 is being used unusually high on the wall. You can mount the Point 2 V2 with the woofer nearest the ceiling, and the PMD angled down into the listening area.
Alternatively, in a 3D audio application such as Dolby ATMOS, DTS:X, and Auro3D, some of the ceiling speakers may be located well in front of the main listening area. The flexible, controlled directivity of the PMD once again allows the sound to be focused where it is needed.

The Importance of a Baffle Wall
Whether used as an in-wall or as an on-wall speaker, the Point 2 V2 is optimized for use on a solidly constructed surface. It should not be mounted in open framing, as this results in improper low frequency loading and many early reflection and diffraction effects that adversely affect performance.
When used in an in-wall configuration, the framing must be 2”x 6” or deeper, as the Point 2 V2is designed to take full advantage of the 5.5” depth found in such framing. Ideally, each loudspeaker is “framed in” much as a window would be framed in. This approach provides the most solid support of the loudspeaker, and surrounding the face of the speaker with either the drywall or plywood wall surface provides both bass reinforcement and the fewest reflection and diffraction problems. !
Wall Construction Suggestions
Having a solidly-built wall is essential for getting the best performance out of any wall-mounted speaker. After all, the wall may not move as much as the speaker diaphragms, but it has vastly more surface area. If it resonates even a bit, it can and will color the sound greatly.
Hence, some suggestions:
1. Using the supplied “ears”, screw the speakers to the surrounding framing rather than to the wall surface (sheet rock, plywood, whatever). The
simplest way to do this is to frame in around the speaker locations so there is only an inch or two of space between the speakers and the surrounding studs. If you are building the walls anyway, the incremental cost of a few extra studs is small. But it will pay off in quieter walls.
2. Use specially designed drywall, such as Quiet Rock. Quiet Rock is a specialized form of sheet rock which has some con- strained-layer damping built into each sheet. More information at http://www.quietrock.com
3. Consider using double-wall construction with a flexible adhesive layer. The best-known of these products is Green Glue; more information is at http://www.greengluecompany.com. Plan on using it between the two layers of a double-layered wall.

4. Always create a smooth Baffle Wall from which the sound of the speaker can emanate with as little interference as possible. You can and probably
should plan on applying acoustic treatments to some of the room surfaces. But make sure that the area around each of the speakers is absorptive rather than diffusive or reflective. And do not simply leave the studs bare and wide open, figuring that the stretched fabric will make it all better. Cut a hole in the wall’s surface just large enough for the face of the speaker itself, and adjust the mounting brackets so that the face of the speaker is flush with the face of the wall.
5. If you are doing a front projection system, choose an acoustically transparent screen material, and cover everything except the speakers themselves with absorption on that front wall. Other parts of the room’s
décor may or may not lend themselves to being covered with fabric. But the front wall will be largely covered, so take ad- vantage of the ease with which you can reduce early reflections from the front wall, and back-and­forth slap echoes along the length of the room.

Making the Point 2 V2 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).
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.
There are many online wire gauge calculators and tables, such as http://www.powerstream.com/Wire_Size.htm
For example, using this table you can estimate that 50 feet of AWG 8 speaker wire (and thus 100 feet of “loop” would have a loop resistance of about 0.063Ω, which would be fine.
Alternatively, the loop resistance can be easily measured with an inexpensive volt­ohm 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. When in doubt, more copper never hurts.

Care & Maintenance
To remove dust from the front of your Point 2 V2, 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 Point 2 V2 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.
