IMPORTANT SAFEGUARDS
INSTALLATION
Water and Moisture - Do not install the appliance near water:
for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool. Heat - Do not install the appliance near sources of heat such as radiators, heat registers, stoves, or other appliances that produce heat. VentIlation - Situate the product so its location or position does not interfere with its proper ventilation. For example, you should not place the product on a bed, sofa, rug, or similar surface that might block the vent openings, or placed in a built-in installa­tion, such as a bookcase or cabinet that might impede the flow of air through the ventilation openings. Wall or Ceiling Mounting - If your appliance can be mounted to a wall or ceiling, mount it only as recommended. Accessories - Do not place this product on an unstable cart, stand, tripod, bracket, or table. The product may fall, causing serious injury to a child or adult, and serious damage to the product. Use only with a cart, stand, tripod, bracket, or table recommended by the manufacturer, or sold with the product.
Any mounting of the product should follow the manufacturer’s instructions, and should use a mounting accessory recom­mended by the manufacturer.
USE
Power Source - Connect the appliance to a power supply only
of the type described in the operating instructions or as marked on the appliance. Power-Cord Protection - Route the power cord so that it is not likely to be walked on or pinched by having objects placed on it, paying particular attention to the plugs, receptacles, and the point where the cord exits from the appliance. Grounding or Polarization - Do not defeat the grounding or polarization feature of the AC power cord. If your AC receptacle will not accept the power cord plug, contact your electrician to install a proper AC receptacle. When not in use - Unplug the power cord of the appliance from the outlet when left unused for a long period of time.To disconnect the cord, pull it out by grasping the plug. Never pull the plug out by the cord. AC Receptacle - Check to make sure that the AC receptacle
holds the power cord plug firmly and securely. If the power cord plug is loose, contact your electrician to replace the defective and unsafe AC Foreign Objects - Be careful that foreign objects and liquids do not enter the enclosure through openings. Cleaning - unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.
SERVICE
Unplug the appliance from the wall outlet and consult qualified service personnel when:
• the power cord or the plug has been damaged.
• a solid object or liquid has fallen into the cabinet.
• the appliance has been exposed to rain or moisture.
• the appliance does not appear to operate normally or exhibits a marked change in performance.
• the appliance has been dropped, or the enclosure damaged. Do not attempt to service the appliance beyond that described in the operating instructions. For all other servicing, refer to qualified service personnel only.

THE BBE PROCESS—"WHAT IT IS"
Loudspeakers have difficulty working with the electron­ic signals supplied by an amplifier. These difficulties cause such major phase and amplitude distortion that the sound reproduced by speaker differs significantly from the sound produced by the original source.
In the past, these problems proved unsolvable and were thus delegated to a position of secondary importance in audio system design. However, phase and amplitude integrity is essential to accurate sound reproduction. Research shows that the information which the listener translates into the recognizable characteristics of a live performance are intimately tied into complex time and amplitude relationships between the fundamental and harmonic components of a given musical note or sound. These relationships define a sound's “sound”.
When these complex relationships pass through a speak­er, the proper order is lost. The higher frequencies are delayed. A lower frequency may reach the listener's ear first or perhaps simultaneously with that of a higher fre­quency. In some cases, the fundamental components may be so time-shifted that they reach the listener's ear ahead of some or all of the harmonic components.
This change in the phase and amplitude relationship on the harmonic and fundamental frequencies is techni­cally called “envelope distortion.” The listener perceives this loss of sound integrity in the reproduced sound as “muddy” and “smeared.” In the extreme, it can become difficult to tell the difference between musical instru­ments, for example, an oboe and a clarinet.
BBE Sound, Inc. conducted extensive studies of numer­ous speaker systems over a ten year period. With this knowledge, it became possible to identify the character­istics of an ideal speaker and to distill the corrections necessary to return the fundamental and harmonic fre­quency structures to their correct order. While there are differences among various speaker designs in the mag­nitude of their correction, the overall pattern of correc­tion needed is remarkably consistent.
The BBE Process is so unique that 42 patents have been awarded by the U.S. Patent Office.
