[. . . ] The bass drivers use laminated steel-core inductors for highpower handling and low saturation. All components are built on high-grade, glass-epoxy, printed circuit boards with thick copper traces to ensure stability and repeatability of performance. Bass Enclosure Construction Enclosure Finish The enclosure of the TAD Reference One's bass drivers features a frame of 21 mm (0. 9 in. ) thick laminated birch plywood supported by a CNC processed plywood back board "spine" up to 137 mm (5. 7 in. ) thick, clad with 50 mm (2 in. ) curved side panels created by high-frequency heating. The bass reflex port was modeled after the design concept of the TAD compression driver and horn, resulting in the reduction of wind noise for clear, deep bass. In order to fully realize the drive unit's potential, the drivers are securely mounted to the enclosure and the enclosure is slanted at a four-degree tilt back, optimizing the unit's center of balance. The 150 kg (330 lb) mass of this system produces a correspondingly powerful bass sound that is both clean and subtle. The teardropshape both reduces sound diffraction, allowing for excellent acoustics, and also serves to eliminate unnecessary resonance and internal standing waves. The enclosure features rare, elegant natural wood that is treated with a transparent finish. Its surface has a beautifully polished mirrored finish, the result of the meticulous, painstaking work of skilled craftsmen. This product is designed to elicit the full potential of the natural wood used in its enclosure. Note that the color and pattern of the wood is slightly different for each unit. TAD Reference One Owner's Manual 7 INSTALLATION AND PLACEMENT Caution: About installation This unit is sold with the understanding that it is to be installed by a properly trained and equipped specialist. All matters concerning installation and mounting should be handled by specialists or by your local dealer. Also, turn the loudspeakers inward so each axis points toward the listening position. Next, connect the audio system as described in CONNECTING THE LOUDSPEAKERS on the next page. Then, optimize the loudspeaker placement as described in OPTIMIZING THE SYSTEM on page 16. Keeping the spikes inserted can cause damage to the bottom of the unit in the event that you move the loudspeaker. Be sure to remove the spikes before moving the loudspeaker to another location. In order to protect the bottom of the unit from damage when moving the loudspeaker, you should place a thick cloth or mat beneath the system before moving it to a new location. 10 TAD Reference One Owner's Manual 12 in.

[. . . ] In areas of high humidity, use a dehumidifier, and in areas of excessive dryness, use a humidifier to adjust the room's humidity level. Avoid exposure to direct sunlight, and do not install in areas near by heating appliances. Conditions considered unpleasant by humans are detrimental to speakers as well. Providing a comfortable environment for the speakers will assist them in demonstrating their best performance. [. . . ]
