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 “Description” 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 Insight Series P4i 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 P4i speakers, conventional speakers sound a bit bland and lifeless. You may also discover yourself hearing details at even modest levels on the P4i 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 ow 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 giving 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 & Installing the P4i
Your new Wisdom Audio Insight Series P4i in-wall speaker is relatively compact, but surprisingly massive compared to most in-wall speakers. Please exercise caution when unpacking your P4i to ensure that you do not strain yourself from its (perhaps unexpected) weight.
- Use the included cardboard template to trace the outline of the hole for the speaker and carefully cut to the line.
- 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 damaging the grille. Set it aside, laying it at.
- Push any insulation in the wall to the side. If there is no insulation in the wall, loosely fill the stud bay with insulation to reduce cavity resonances and improve performance.
- 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.
- Make sure all of the speaker clamps are retracted in their “ready-to-mount” position at the tops of the mount towers, tucked within the mounting opening’s border.
- Insert the speaker straight into the mounting opening. Tighten the speaker clamp screws on the front of the speaker baffle. The speaker clamps will automatically rotate into position and begin clamping the speaker.
- When you notice resistance on the screws the speaker has been clamped successfully. IMPORTANT: Always use low-torque settings. NEVER overtighten the clamp screws.
Your P4i 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 in the wall, your P4i 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 set up 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 & Maintenance
To remove dust from the front of your P4i, 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 P4i 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.
