Unpacking
Your new speaker system has been very carefully packaged to
insure that it travels to you safely. Each speaker is protected by a
double-wall 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.
Connections
At the top end of your Skyline you will find a terminal plate
housing one pair of five-way binding posts.
Connect the output of the rear channel amplifier to the
loudspeaker via the gold five-way binding posts provided. Dual
banana plugs or gold spade lugs are recommended means of
termination.
Be sure that you observe polarity when making the
connections. The positive (+) terminal (red) of the amplifier
should be connected to the positive terminal of the loudspeaker.
The negative (-) terminal (black) of the amplifier should be
connected to the negative terminal of the loudspeaker.

Speaker Placement and Installation
A pair of Skylines can be mounted vertically or horizontally,
along the top of a side wall, high in room corners or along the
top of a rear wall.
NOTE: Ceiling height in most listening rooms ranges between 7
to 12 ft., so most of the recommendations here are based on
that model. If you have an unusual room situation (cathedral
ceiling, lofts, exceptionally high or non-level ceiling) and are
unsure about optimal placement for the Skyline feel free to call
us at 800-283-4644.We’ll be happy to help.
Once a speaker position has been determined the Skyline
mounting brackets should be mounted on the wall first.
Items needed before beginning to attach wall brackets.
• Cordless electric drill/screwdriver
• Pencil
• Stud finder (optional)
• 1/8” drill bit
Instructions for attaching brackets to wall:
1. Select a mounting site. Try finding a site with solid
wood backing.
2. On the portion of the bracket that will connect to the
back of the Skyline are four keyhole shaped holes that
correspond to the four screws on the back of the Skyline.
In addition to the keyhole shaped holes you will notice a
fifth hole.This fifth hole corresponds to the plunger hole
on the back of the Skyline. If mounting the Skyline in a
three-wall corner, (whether mounting vertically or
horizontally), the plunger hole should be on the half
closest to where all three walls meet.The plunger hole
corresponds to the side of the Skyline that houses the bass
section. The bass section should point INTO the
corner to benefit from bass extension provided by
all three walls.
3. Using one of the brackets as a pattern, mark eight
holes on the wall that correspond to the screw holes on
the vertical top and bottom of the bracket.

4. Drill eight 1/8” (.32cm) diameter holes as marked.
In some cases we’ve found that a satisfactory mount can
be made just using the inner four holes, provided there is
a stud present.
5. Fasten bracket to wall with wood screws provided.
6. If mounting in a three-wall corner, make sure to
connect speaker cable and tighten binding posts
before attaching the skyline to its bracket.This would be
extremely difficult to do afterwards.
7. Carefully line up the 4 screws on back of the
Skyline with the larger round portion of the 4 key
shaped holes. Make sure the plunger hole on the back of
the speaker corresponds with the plunger hole on the
mounting bracket.You should be able to feel the speaker
slide into place as the screws move into their
corresponding hole.
8. Once your sure the screws are through the holes, lock
the speaker in place by sliding it in the direction away
from the plunger hole, (down if mounted vertically) a
slight snapping sound will indicate that the speaker is
locked in place.

Designer’s Note from Bill Dudleston.
Conveniently tucked away in room corners, Skyline will
disperse music evenly throughout the listening area.
Legacy’s exclusive ACOUSTIC POLAR HYBRID TECHNOLOGY
cancels early midrange reflections to avoid the “cardboard honk”
sound characteristic of some in-wall and on-wall speakers.The
midrange and highs will sound open and detailed; music will
literally seem to be suspended in air.
Whether mounted horizontally or vertically, Skyline takes full
advantage of the bass reinforcement corners provide. Skyline
benefits from 9 dB of bass reinforcement when mounted in
ceiling corners.The special 7” carbon-polymer woofer pumps out
more than twice the bass one would expect from a speaker of
it’s size.
Utilizing the Manhattan system’s extraordinary 5.25” Kevlite-Ti
midrange and the silky smooth NEOdome tweeter, Skyline will
integrate perfectly with the Empire front channel speakers to
satisfy the most critical listeners.
With the increasing popularity of discrete multichannel audio
formats like Dolby Digital 5.1 and DTS, the characteristics of a
direct radiating surround speaker quite desirable. Conventional
direct firing speakers placed to the side of the listener can create
a hot spot,“overcooking” the listener seated in proximity and
thus drawing attention to themselves. Mounting the speakers
higher on the sidewall can reduce this problem but may lead to
vertical lobing error in the polar pattern. Skylines are designed to
be mounted high to eliminate the “hot spot” problem with an
optimized polar pattern, firing toward the listening position.
ACOUSTIC POLAR HYBRID TECHNOLOGY
The Skyline is a hybrid; open air/sealed box loudspeaker.
The satellite section is mounted in open air to provide an
open sound and a narrower radiating pattern.The bass section is
built into a sealed enclosure to provide the reinforcement we
need to achieve the low frequency reinforcement needed. The
additional reinforcement achieved when corner-mounting
provides output one would expect from a box three times
Skyline’s size.

The Cabinetry
Beneath the surface of Skyline’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”. We continue to stand behind it
with a solid ten year warranty, more than twice the industry
standard.

Hook-up Cables
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.
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 run of 20 feet of 18 gauge can cause
up to 10% deviations of crossover center frequencies. That same 20
feet can undamp your damping factor and reduce your systems’
output by one-half decibel.
The best way to approximate the ideal would be to keep
loudspeaker leads as short as is practical. However, for rear room
installation, cable runs exceeding 50 feet are not unusual. Using an in-
wall approved cable of 12 guage is recommended.

The Amplifier
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 an efficient load
to 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.
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 than 1% of electrical power is converted
into acoustic output. For example, an omni-directional transducer
with an anechoic sensitivity of 90 dB @ 1w/1m has a full space
efficiency of only 0.63%. 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 to the left.
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.
