The Cabinetry / Our Commitment

Handcrafted
Beneath the surface of Pixel’s elegant exterior lies rigid MDF construction. Interlocking joinery maximizes the strength of the cabinet parts. Polyester fiberfill is selected for internal damping. A sharp rap on the enclosure will leave you with little more than bruised knuckles.

Each cabinet is impeccably finished on all exposed surfaces with select veneers. The exquisite finish is hand-rubbed several times to assure a patina at home with the most elegant decor.
Our Commitment
A great deal of forethought, love, and satisfaction is instilled in each piece of Legacy workmanship. We take pride in getting to know many of our customers on a first-name basis.
Your purchase of this product is backed by the renowned “Legacy Satisfaction Guarantee”.

Speaker Installation

Select the wall locations for the Pixel system. Try to create a 60-degree angle horizontally between the speaker pair, relative to the listening position. This usually results in a 10-foot horizontal spread between the speakers, center to center. Recommended mounting height for the loudspeaker puts the wall bracket screw holes between 62″-68″ off the floor. This may be adjusted slightly to accommodate the sightlines of the monitor.
Precautions
If you have any doubts about your ability to properly install in/on-wall loudspeakers, you should consider the services of a custom installer. If you plan to install them yourself, always use high-quality tools to save time and make the installation go more
smoothly. Determine the final location of both left and right speakers before drilling or cutting any holes since changes to one speaker may affect the other either aesthetically or acoustically. Look for pipes, wiring, or any other conflicting material that might be damaged before beginning the installation.
There are several ways to install Pixel, depending on which version you are using:

Pixel Pro On Wall Installation: Page 8
Pixel Pro In-Wall Installation: Page 9

Pixel On Wall Installation

The Pixel is provided with a pre-installed solid aluminum wall bracket. Locate the desired height for the top of the speaker with the lower edge of a piece of masking tape on the wall. Now measure 3.25″ downward. This is the height that the provided bracket will need to have the two mounting screws installed. Once this height is determined, use a level to set the bracket position and mark the two-hole locations onto the wall. The grooves in the bracket should be against the wall and oriented down as illustrated.
If the hole locations do not coincide with wall studs, use the included plastic wall inserts. These threaded inserts do not tear out as a moly bolt or expanded inserts can. Screw the inserts into the drywall until flush (do not strip by over-tightening). Now attach the bracket with the provided screws. When sliding the Pixel onto the wall bracket, start with the top of the speaker an inch or two above your tape mark, press gently against the wall, and lower down slowly. Do not let go of the speaker until you are
certain it is fully locked into the wall bracket.

Pixel Pro On Wall Installation

Pixel Pro follows the same mounting instructions as page 7, using the included pair of Z-clips as shown with the longer bar clip anchored to wall studs.

Pixel Pro In-Wall Installation

Pixel Pro can be ordered with an oversized outer baffle to allow for in-wall installation.
The outer baffle is 18.75″ long and 18.5″ wide. Four mounting screws are to be installed through the center of the grille cups into the wall framing.
Care should be taken to avoid electrical or plumbing- before cutting into the wall or installing screws into studs.

Hooking Up Cables

The ideal conductor would have negligible resistance, inductance, and capacitance. The table below shows how a few actual speaker cables measure up.

Capacitance is considered insignificant in each cable because its effect is well out of the audio bandwidth; inductance can be de- creased (at the expense of increased capacitance) by keeping the conductor pair closely spaced. How long would a cable have to be before inductance effects would impinge on the audio spectrum? Approximately 300 feet of 12 gauge would be required to establish a corner frequency of 20 kHz with an 8 Ohm loudspeaker. As you see, inductance is not a problem for most of us.

Hooking Up Cables

What about phase shift due to frequency-dependent travel times down the speaker cable? Measurements show that 100 Hz waves will be delayed about 20 billionths of a second behind 10 kHz waves when traveling to the end of a 10-foot speaker cable. Since the cilia of the ear require 25,000 times longer than this just to transmit phase information, phase shifting is obviously not the primary concern when considering speaker cables. What about resistance? Finally, we are getting somewhere. Resistance is the controlling factor of the amplifier/loudspeaker interface. Excessive resistance can cause major shifts in speaker crossover frequencies. The lower the impedance of the loudspeaker, the greater the effects of series resistance. A 20 foot run of 18 gauge cable can cause up to 10% deviations of crossover center frequencies. That same 20 feet can un-damp your damping factor and reduce your systems’ output by one- half decibel. In summary, there are no perfect cables. The best way to approximate the ideal would be to keep loudspeaker leads as short as is practical.

Amplification

Ideally the loudspeaker would be among the first components selected when assembling a play-back system. This would allow the user to choose an amplifier capable of delivering adequate amounts of current into the frequency-dependent load presented by the loudspeaker.
However, when upgrading a system, audiophiles may find themselves matching their new loudspeakers to their existing amplification. For this reason, extensive measures have been taken to ensure that each Legacy speaker system represents a smooth, non-reactive load to virtually any amplifier.

Often there is much confusion regarding amplification and loudness levels. It should be understood that the role of the amplifier goes beyond that of driving loudspeakers to a given sound pressure level. The amplifier should be able to CONTROL the loudspeakers across the entire music spectrum. This means that parameters such as damping factor (values greater than 60 are acceptable) and dynamic headroom should not be overlooked when comparing amplifiers.

Amplification

How much power will your new speakers need? That ultimately depends on your listening environment and musical tastes. As little as five watts per channel should drive them to a level satisfactory for background music. A typical 45 watt per channel receiver may fill a room with the compressed mid-band energy of “heavy metal,” but seem to lack weight or control with classical recordings. Some audiophiles feel that 200 watts per channel are the bare minimum to avoid audible clipping distortion when reproducing music at “live” playback levels. Your Legacy speakers are designed to take advantage of “high- powered” amplifiers, so don’t be afraid to put them through their paces.
How much is too much power? Rarely is a drive unit damaged by large doses of music power. More often than not the villain is amplifier clipping distortion. Even though decades of refinement, loudspeakers are still notoriously inefficient transducers, requiring huge amounts of power to recreate the impact of the live performance. Typically less than 1% of electrical power is converted into acoustic output. (For example, an omnidirectional transducer with an anechoic sensitivity of 90 dB @ 1w/1m has a full space efficiency of only 0.63%)

Amplification

When an amplifier is unable to fulfill your loudspeakers demands, a damaging harmonic spike may be leaked to the high-frequency drivers.
Another important point regarding loudness is that the dB scale is a logarithmic one. This means that a 150 Watt amplifier will potentially sound only twice as loud as a 15 Watt amplifier. If all of this discussion of power and loudness seems a bit abstract, consider the example below.
The average acoustical power developed by a person speaking in a conversational tone corresponds to a mere 0.00001 Watts. The power that would be developed by the entire population of the city of New York speaking at once would barely illuminate a single 100 Watt light bulb.

Speaker Connections

The Terminal Plate
At the bottom rear of each of your Pixel loudspeakers, you will find a recessed cup housing one pair of binding posts.
Hook the high-level speaker inputs from the main amplifier to the pair of the binding posts. Be sure that you observe polarity when making the connections. The positive (+) terminal of the amplifier should be connected to the positive terminal of the loudspeaker. The negative (-) terminal of the amplifier should be connected to the negative terminal of the loudspeaker.
