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 “Description” for more information. About this manual 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 in order to better understand your system’s full capabili- ties. Registering your warranty 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.

eral 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 perfor- mance 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 de- signs. Planar magnetic drivers 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. The motive force is pro- vided by a “voice coil” that is printed on the film, which is suspended in a strong magnetic field provided by pow- erful magnets behind and in front of the film. The ratio of available force to the moving mass is huge, which means that the diaphragm does exactly what it is told: nothing more, nothing less. Free from compression 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 flat 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 con- ventional 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 P6i speakers, conventional speakers sound a bit bland and lifeless. You may also discover yourself hearing details at even modest levels on the P6i that were pre- viously inaudible even at loud volumes on more conventional speakers. More reliable The “voice coil” in the planar magnetic driver is spread out over a large, flat area that is exposed to the open air. As such, when a huge transient comes along,

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. Easy on amplifiers 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. Dynamic woofers 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 perfor- mance 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. Extraordinary 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. Spe- cifically, 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 extraordi- nary 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 acous- tic “spring.” Recommended and minimum enclosure volumes for the speaker are listed in the Specifications section, and repeated on the Dimensions page. Optimized for subwoofers 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” make blending them seamlessly with a high quality subwoofer almost impos- sible. All Insight Series speakers have been designed for optimally flat response to 80 Hz, which is the most-common crossover frequency used with subwoofers.

It is impossible to separate the performance of a speaker from the room it is in. No matter how well designed, a speaker will sound quite different in a carpeted library with lots of bookcases, heavy drapes, and overstuffed furniture than it would in a stone-and-glass great room. Fortunately, even mid-priced receivers today have basic room correction ca- pabilities. Some of these auto-equalization systems work better than others, but they all measure the response of the speaker in the room, and give you the option of trying to make the sound “flat.” Which is to say, all frequencies are reproduced at an equal volume when equal energy is put into the speaker. Unfortunately, there are important differences between how our ears hear “flat” and how the microphone measures “flat.” Specifically, our hearing is quite adept at separating the direct sound from early reflections, and from subsequent rever- beration in the room. The measurement systems commonly used in room cor- rection do not make this sort of distinction. If you do not make an allowance for this difference, you often end up with worse sound, not better. Your Insight loudspeaker addresses this important difference. See “Room Cor- rection” for more detailed information.

Your new Wisdom Audio Insight Series P6i in-wall speaker is relative compact, but surprisingly massive compared to most in-wall speakers. Please exercise caution when unpacking your P6i to ensure that you do not strain yourself from its (perhaps unexpected) weight. Simple installation instructions 1. Use the included cardboard template to trace the outline of the hole for the speaker and carefully cut to the line. 2. Carefully remove the magnetic grille, tipping it off from one side to the other (not from one end to the other), so as to avoid damag- ing the grille. Set it aside, laying it flat. 3. Unscrew and remove the speaker module itself (baffle plate, driv- ers, crossover) from the UniGrip™ mounting system and carefully set it aside. 4. Remove one long clamping rail from the Uni-Grip™ mounting system, and loosen the other side. Angle the Uni-Grip into the cutout so the remaining clamping rail is sandwiching the wall, and snug it down lightly. Insert the removed clamping rail through the wall opening, and reattach it to the Uni-Grip. Check everything for plumb, and snug both rails down. 5. Push any insulation in the wall to the side. If there is no insula- tion in the wall, loosely fill the stud bay with insulation to reduce cavity resonances and improve performance. 6. Using assistance to hold the speaker away from the wall, connect the speaker cable to the + and – connectors on the rear of the speaker, paying attention to proper polarity. 7. Screw the speaker module into the Uni-Grip frame. 8. Place the grille on the front of the speaker, registering it around the edges of the baffle. It is held magnetically and will gently snap into place. Maximum wall thickness The Uni-Grip system on the P6i can handle wall thicknesses of up to 1.25” (11⁄4” or 3.175cm). If you are planning a double-wall construction, you may use two 5⁄8” layers. You may also consider using MDO (medium density overlay) ply- wood, which is quite strong and has a smooth paper surface like gypsum board.

a speaker from the room in which it operates. As such, we are big believers in both room treatment (to whatever degree it is practical) and room correction (equalization) to mitigate the sonic damage that even good rooms can cause. In fact, we include an extremely sophisticated room correction system in all our Sage Series and Wisdom Series systems. Fortunately, effective room correction is widely available today in even mid- level AV receivers. Unfortunately, the target curves employed and functionality of these systems vary widely. A solution to this problem is built into your Insight Series P6i in the form of the Response switch on the front of the speaker (near the bottom). No room correction If your system does not include any form of room correction (or you choose not to use it), we suggest listening to the system for some time with all the switches in the Target position. Once you are accustomed to the sound of the system, switch them all to Flat. In most (but not all) rooms, Flat will actually sound a bit too bright. Decide which position you prefer (which is room-dependant) and settle in to enjoy the system. Systems with room correction Most room correction systems have the option of compensating for room acous- tics in such as way as to create a nominally “Flat” response. While one would think that this would be the most desirable, in most rooms it sounds subjectively bright and fatiguing. The reason is simple: we hear sound differently than the microphone measures it, and we must make an allowance for that difference in order to achieve the best results. Specifically, our ear/brain system is extremely good at sorting out the direct sound from early reflections, and from subsequent reverberation. Most measure- ment systems lump all of these things together, creating something of an average of all three. If you do not allow for this disparity, the direct sound (which should be flat) ends up being tilted up at high frequencies in an effort to restore energy that has been absorbed by the room. The result may measure flat, but we perceive it as too bright (because the direct sound is, in fact, too bright.) Thus, the most reliable way to calibrate the system is as follows: 1. Set all speakers to the Flat position. 2. Use your room correction system to calibrate to a Flat response in the room. 3. When the correction is complete and saved, listen to the system with all speakers in the Target position (which makes an appro- priate allowance for the absorption found in typical residential rooms). As before, you can compare Flat to Target. But in most

Using with subs All Insight Series loudspeakers are optimized for use with subwoofers, with a crossover of 80 Hz. (This is the most common frequency below which subwoof- ers are used.) When properly installed in the wall, your P6i has inherently flat 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 set up your surround processor for a crossover of 80 Hz and define all your Insight speakers as “Small” in the speaker setup portion of your proces- sor’s menu system. Doing so ensures that all content below 80 Hz is directed to the subwoofer(s) for reproduction. Using full range In some installations, the Insight Series speakers may be used full-range rather than with a subwoofer. If so, we recommend using a two-pronged approach to get the lowest distortion and best performance from your Insight Series speakers. 1. Purchase and install 70 Hz in-line filters such as the ones found here, at Parts Express: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=266- 272 2. Optionally, if your system has some basic EQ capabilities, boost the range around 60 Hz by perhaps 3 dB The combination of these two filters will yield full-sounding natural bass, while attenuating the lowest frequencies that normally would be reserved for a sub- woofer.

To remove dust from the front of your P6i, 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 P6i 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.
