The Cabinetry / Our Commitment
Handcrafted
Beneath the surface of Silhouette’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
There are several ways to install Silhouette, depending on which version you are using.
Select the wall locations for the Silhouette 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
at 61.5" off the floor. This may be adjusted slightly to acommodate the sight lines of the
monitor."
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.

Precautions
Silhouette On Wall Installation
When mounting Silhouette flat on the wall, use the included pair of Z- Clips as shown with the longer bar clip
anchored to wall studs.

Silhouette Pro In Wall Installation
After positioning the speakers, use a
drywall saw to cut an opening slightly
larger than the 12.15" x 35.5" cabinet
body.
The outer baffle is 37" long and 17.5"
wide. Six 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 wall or installing screws into
studs.

The ideal conductor would have negligible resistance, inductance
and capacitance. The table below shows how a few actual speaker
cables measure up.
Cable Ωs/ft pF/ft µH/ft
12 ga. 0.0033 24 0.21
14 ga. 0.0048 17 0.13
16 ga. 0.0079 16 0.18
18 ga. 0.0128 28 0.21
Capacitance is considered insignificant in each cable because its effect is well out of the audio bandwidth; inductance can be decreased (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
10
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 requires 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 of 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.

Ideally the loudspeaker would be among the first components selected when assembling a playback 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
12
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 is 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 through decades of refinement, loudspeakers are still notoriously inefficient transducers, requiring huge amounts of power to recreate
the impact of the live performance. Typically less that 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
13
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.

The Terminal Plate
Speaker Connections
At the rear of each of your Silhouette loudspeakers you will find a terminal plate housing one pair of binding posts.
Hook the high level speaker inputs from the main amplifier to the pair of binding post. 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.
