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.
