NOTES ON
MEASUREMENT CONDITIONS
1. Pink noise signal, one Watt calculated using EVZmin,
3.16 meter-measurement distance referred to one meter.
2. On-axis, one Watt calculated using E^/Zmin, 3.16 meter-
measurement distance referred to one meter, low frequen­
cies corrected for anechoic chamber error.
3. This system rating patterned after the AES method for indi­
vidual driver, where the test signal is pink noise with a 6 dB
crest factor over the bandwidth of the system, with power
calculated using the EVZmin, for two hours.
4. This measurement made under the same conditions as Pres­
sure Sensitivity, but at rated power, and takes into account
any power compression effects due to non-linearities in the
system.
5. The loudspeaker should be connected to the 8-ohm (4-ohm)
tap on amplifiers using transformer coupled output sections.
6. Distortion components invalid above 10 kHz. The distortion
at any given frequency may be found by graphically taking
the difference between the fundamental and harmonic, and
adding the number of Decibels which the harmonic has been
raised on the graph and apply the formula:
% distortion = 100 X 10<
Finishing Enviro-Board " is simple and straight
forward as long as a few things are understood:
1. Enviro-Board'" has been tested with a large num­
ber of commercially available paints with 100%
success. However, it is impossible to test every
paint available. Altec Lansing therefore recom­
mends that you test a small area on the rear of
the cabinet or under the grille to check there are
no adverse effects.
2. Ensure the surface is clean and free of grease (use
soapy water if necessary).
3. Any latex-enamel or acrylic-based paint can be
used but the high-tech top layer of Enviro-Board"
was developed in conjunction with Pittsburgh
Paints. They developed their Manor Hall® Exte­
rior House series of paints to compliment the
Enviro-Board'". Altec Lansing recommends the
use of these paints in adverse or tough situations.
4. Water-based Latex paints in particular can take a
considerable time to dry fully. They can be
handled in a few hours but full strength may not
be achieved for a week, particularly in damp or
cool conditions.
5. The paint can be applied with a brush, roller or
spray. Care should be taken not to get paint on
the woofer cone.
6. Stain can be used to highlight the grain in the
Enviro-Board " or match real wood. Care should
be taken when using stain because it is impossible
to refinish the material after staining. A good
approach is to use a stained varnish but be care­
ful as it is very difficult to lighten a stain.
HANGING AcoustaBASS
The AcoustaBASS family of products has been
developed and is fully integrated with the ASK family
of hanging hardware. Each ASK kit consists of a steel
tube, two brackets, two eye-bolts and fasteners. The
Altec Lansing contractor installs the ASK by drilling
two holes into the enclosure in predetermined posi­
tions and assembling the ASK kit. Full instructions arc
included with each ASK kit and a template is packed
with the
AB8500 to show the location of the holes.
A single AB8500 requires a single ASK-300 to sus­
pend it horizontally, or a single ASK-100 to suspend
it vertically. While each AB8500 requires two ASK-
100 (horizontal), or two ASK-300 (vertical), if mul­
tiple cabinets are suspended (up to a maximum of 3).
Full attention should be given to the instructions and
limitations in the ASK instruction sheet.
