Handcrafted
Beneath the surface of Marquis’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”.

Your new subwoofer has been very carefully packaged to insure that it
travels to you safely. Each subwoofer 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.

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. Careful
adjustment of the convenient front panel controls will lead to seamless transition.
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.
