The Cabinetry / Our Commitment
Handcrafted
Beneath the surface of Goliath XD’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”.
4
Warranty
Legacy Audio supports its customers and products with pride. We cheerfully warrant our loudspeaker products we manufacture from defects in materials and workmanship for a period of seven
(7) years. Electronic components such as internal amplifiers and digital processors are covered for
three (3)years. Please register your product with Legacy Audio. Should you require service Legacy
will require a proof of purchase in order to honor the warranty - so please keep your receipt.
• The warranty applies to the original owner and is not transferable.
• The warranty applies to products purchased from an “Authorized Legacy Dealer”.
• The warranty on active components such as digital processors or internal amplifiers is limited to three
(3) years of coverage.
• The warranty on dealer stock will extend for a maximum of two years from invoice.
The warranty does not cover transportation costs of product to or from the customer, distributor or
dealer, or related shipping damage.
Exclusions from Warranty

5
Unpacking Your Speakers
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.

Speaker Placement
Since the human ear is rather poor at localizing radiation frequencies
below 125 Hz, good results may be obtained in a variety of room
placements.
Low frequency reinforcement occurs whenever woofers are placed near
room boundaries. The distance from the walls, floor and ceiling
correspond to the wavelengths of the frequencies, which will reflect in
phase and thus reinforce bass output. Therefore, the actual dimensions of
your listening room play a definite role in what ultimately arrives at your
ear. In fact, rooms tend to have their own set of favored frequencies.
We can calculate what the most strongly reinforced frequencies in a room
will be by the formula shown below:
Resonant Frequency = (1130 ft/sec) / (ft. between boundaries x 2)
For example, a room with an 8 ft. ceiling height has a strong resonance at:
(1130 ft/sec.) / (8 ft. x 2) = 71 Hz.
7
Speaker Placement
Now, while such reinforcement might actually be beneficial at very low
frequencies, a way to minimize excitation of these resonances is to place
your subwoofer asymmetrically relative to room boundaries. For instance, if
the subwoofer is 2 ft from one corner wall, then place it 1.5 ft to 3 ft from
the other.
Placing the subwoofer in a corner will reduce the radiation angle and thus
increase efficiency. It will also excite the maximum number of room modes
and decrease distortion.
A best case scenario is to actually use two subwoofers, one to each side
of the listener. The subs should be placed 90° out of phase with each
other. This improves spaciousness and bass uniformity, with a reduction in
room level peaks.

Speaker Connections
Once you’ve found a place in your room, the next step is connecting the Goliath XD to your
existing system.
Option 1: Connecting one or two Goliath XD using LFE output
If you are utilizing Goliath XD as the dedicated LFE channel for a surround system, connect the
LFE output from your surround processor to the XLR input 3 of your Xilica processor. Connect an
XLR cable from the Xilica processor output 1 to the XLR input on the rear of the Goliath XD
subwoofer.
If you will be connecting a second
Goliath XD to your LFE channel,
connect an XLR cable from the
Xilica processor output 5 to the XLR
input on the rear of the right Goliath
XD subwoofer.
9
Speaker Connections
Option 2: Connecting one or two Goliath XD for use with Legacy
Helix, Whisper, or Aeris
If using the Goliath XD to augment the bass performance of a Legacy Audio
speaker system begin by connecting the left preamplifier output to XLR
input 1 on the Xilica processor (and input 3 if using a splitter). Next connect
the right preamplifier output to XLR input 2 on the Xilica processor (and
input 4 if using a splitter).
Connect an XLR cable from output 4 of the Xilica processor to the back
of the Goliath XD subwoofer.
If you are using a second Goliath XD subwoofer, connect an XLR cable
from output 8 of the Xilica processor to the back of the right Goliath XD
subwoofer for stereo subwoofer performance.

Powering Up Goliath XD
1. Power Cable: The supplied power cable will plug into the socket on the back terminal
plate of the unit.
NOTE: Try to plug into the same AC circuit as the rest of your audio system, as this will avoid
hum from ground loops.
2. Power Up: In the rear of the subwoofer is the power switch. Push the switch upward to
turn the unit on.
NOTE :
Power up the Xilica processor before the Goliath XD subwoofer to avoid sending
unnecessary transients through the subwoofer.

Fine Tuning
Adjusting Goliath XD
Gain: This will allow you to adjust the volume level played by the subwoofer. It only controls
the subwoofer level, not the level of any of the other loudspeakers in the system. Be sure to
adjust the Gain in the row corresponding to your subwoofer.
Filter: Clicking this button allows you to access the EQ capabilities of the subwoofer. The
crossover point and slope can also be adjusted on the right via the X-Hi/LPF section. Follow
the instructions on the previous pages for making adjustments.
Polarity: This control is essential in the proper setup of your subwoofer. If not set up
properly, your main speakers and subwoofer can actually work against each other. If
operating out-of- phase the subwoofer and mains will cancel, creating nulls at some
frequencies (primarily upper bass).What is desirable is to have the subwoofer and the mains
operating in phase, relative to the primary listening position. Here is an effective method of
accomplishing this:
While seated at your listening position, click the Polarity button on your subwoofer output.
Using pink noise or a 50-60 Hz test tone, listen for the strongest output. Next, play music
program material and optimize the level and polarity settings, adjusting for the smoothest
output.

Designer’s Notes
•Goliath XD is a carefully engineered subwoofer, capable of integrating with the fin-
est speakers.
• Unlike many woofers that suffer from overshoot, Goliath XD applies a special EMF
countering circuit, which increases power handling and radically reduces low frequency distortion.
• An enormous stacked magnet structure is custom fabricated to provide excellent
sensitivity. This unit is bolted in compression to secure nearly 80 lbs. of motor structure.
• Two separate high current 500 watt amplifiers (1,000 watts total) maintain control
of Goliath XD’s multiple 15” sub-bass pistons.
(From Bill Dudleston)
• The subwoofer alleviates the deep bass demands from compact satellite speakers,
thus preventing low frequency strain due to long excursion.
• TheXilica processor allows for precise control over Level, Crossover Frequency
and Phase, allowing Goliath XD to integrate precisely into your system.
