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.
