ACOUSTIMAX User Manual
For your protection, please read these
safety instructions completely before operating the appliance, and keep this manual
for future reference.
Carefully observe all warnings, precautions
and instructions on the appliance and
described in the operating instructions

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.
