Handcrafted
Beneath the surface of Phantom’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”.

Warranty

Your new speaker system has been very carefully packaged to insure
that it travels to you safely. Each speaker is protected by a doublewall outer carton with heavy V-board corner protectors. Molded foam
end caps are used to protect the elegant cabinetry, and a plastic liner
is provided as waterproofing. Please save this packing for future
transportation. If cartons become damaged or misplaced, new ones
can be purchased from Legacy Audio.

Precautions
If you have any doubts about your ability to properly install 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. The Phantom On-Wall
Loudspeakers mount on standard 16-in center stud walls. Determine the
final location of both left and right speakers before drilling 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.
Speaker Installation

- There are two options when mounting
the Phantom Loudspeaker. The bracket
can be mounted either vertically on one
stud or horizontally on two 16-inch center
studs.
- Place the provided screws in the
appropriate holes based on how you wish
to mount your speakers. Please see
figure 1.

Vertical Mounting
- Find the center of one stud and mount the
provided bracket using the provided screws. Place
screws in the holes highlighted in red in figure 2.
- Lift the cabinet and slide the screws on the back of the
cabinet into the keyholes. This may take two people to
accomplish this task.

Horizontal Mounting
- Find the center of the two studs and mount the provided bracket using
the provided screws. Place screws in the holes highlighted in red in figure 3.
- Lift the cabinet and place the screws on the back of the cabinet into the
keyholes. Slide the cabinet to lock it into place. This may take two people
to accomplish this task.

Before you purchase loudspeaker wire, check local building codes to
make sure that the wire is rated to comply with applicable local
safety codes such as UL or CL-2. Use only stranded wire no thinner
than AWG 16. For runs longer than 100 feet, we recommend minimum of AWG 14. When pulling wire, take care not to pull the wire
too fast to prevent stretching the wire or scorching the insulation
from friction. Leave 2 to 3 feet of excess loudspeaker wire at both
ends; it is easier to trim off excess wire than to splice additional wire.
When securing the wire inside the walls, be careful not to pierce the
insulation with nails or staples.
Hooking Up Cables
12
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
13
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 onehalf 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
15
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
16
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.
