Page 3: Owners Record
The serial number is located on the rear of the unit. Record this number in the space provided below. Refer to this when calling your dealer regarding this product. Model: Cinema HD Serial No: Date of purchase: Thank you for selecting a Legacy Loudspeaker System. These hand- crafted instruments will provide you with many years of listening en- joyment. -
Page 4: The Cabinetry / Our Commitment
The Cabinetry / Our Commitment Handcrafted Beneath the surface of Cinema HD’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. -
Page 5: Warranty
Warranty Legacy Audio supports its customers and products with pride. We cheerfully warrant our loud- speaker 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. -

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. -
Page 7: Speaker Placement
Speaker Placement To allow more flexibility in seating arrangements, your Legacy loudspeaker is designed for broad lateral coverage. Optimal listener position is actually about 5 to 15 degrees off of the axis normal to the loudspeaker baffle (approximately 4-5’ off the floor). -
Page 8: Hooking Up Cables
Hooking Up Cables The ideal conductor would have negligible resistance, inductance and capacitance. The table below shows how a few actual speaker cables measure up. Ωs/ft Cable pF/ft µH/ft 12 ga. 0.0033 0.21 14 ga. 0.0048 0.13 16 ga. 0.0079 0.18 18 ga. - Page 9 Hooking Up Cables 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.

Page 10: Amplification
Amplification Ideally the loudspeaker would be among the first components selected when assembling a play- back system. This would allow the user to choose an amplifier capable of delivering adequate amounts of current into the frequency dependent load presented by the loudspeaker. However, when upgrading a system, audiophiles may find themselves matching their new loudspeakers to their existing amplification. - Page 11 Amplification How much power will your new speakers need? That ultimately depends on your listening environment and musical tastes. As little as five watts per channel should drive them to a level satisfactory for background music. A typical 45 watt per channel receiver may fill a room with the compressed mid-band energy of “heavy metal,”...
- Page 12 Amplification When an amplifier is unable to fulfill your loudspeakers demands, a damaging harmonic spike may be leaked to the high frequency drivers. Another important point regarding loudness is that the dB scale is a logarithmic one. This means that a 150 Watt amplifier will potentially sound only twice as loud as a 15 Watt amplifier.

Speaker Connections The Terminal Plate At the rear of your loudspeaker you will find a terminal plate housing two rows of jumpered binding posts. The upper row is the input to the "satellite" portion of the speaker. The lower row is the input to the "subwoofer"... -
Page 14: Fine Tuning
Fine Tuning To facilitate proper set-up of your speakers in a variety of room situations, we have included several heavy duty toggle switches on the terminal plate, located on the back of the loudspeaker. All switches in the “up” position represent the “anechoic flat”... -
