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”.

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.

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.
