tion convenience for commercial and residential applications. Because of their weather
resistant properties, you can use them indoors or outdoors- wherever great sound is
desired. For information on our other products, go to www.mtx.com or call 1-800-

PLACEMENT
Outdoor use:
The materials used in the construction of the MTX All Weather Speakers systems
are weather resistant for use in even the harshest conditions. The hardware is brass,
the grille is powder-coated aluminum, and the bracket is zinc plated, powder coated
steel. The enclosure itself is shatter-resistant. Adhering to just a few mounting guide-
lines will further extend the life of the product.
Whenever possible, mount the speaker under an eave or other protective overhang.
Always aim the speaker at a slight downward angle to prevent water from accumulating
on the speaker cone.
Do not place the speaker in a location where water, snow or ice will accumulate on the
speaker for extended periods of time.
Indoor Use:
The MTX All Weather Speaker system works very well when it is wall mounted in
indoor applications. When you place the speaker on a wall, you take advantage of the
natural boundary effect that occurs when a speaker system is placed against one or
more surfaces. This boundary effect will provide increased overall output. When you
mount the speaker against one surface (on a wall) you increase output by 3dB. When
you mount the speaker against two surfaces (on the wall near the ceiling) you increase
the output by 6dB. When you mount the speaker against three surfaces (in a corner
near the ceiling) you increase the output by 9dB. Please note that the AW52 and AW82
include magnetic shielding (bucking magnets) to minimize interference when placed
near CRT monitors.
Shelf Mounting:
The bottom surface of the AW52 and AW82 is sloped to maintain level orientation
when shelf mounted.
Down Firing:
The MTX All Weather Speaker systems also work well in a down firing configuration
for spaces utilizing open beam ceilings such as offices, restaurants and warehouses.
When determining speaker spacing in down-firing installations you can use the follow-
ing chart:
AW52=120
o
nominal coverage (60
o
off axis) at 2 kHz
Ceiling Ht: 8’ Spkr Spacing: 11’ Max SPL @ 30W (Listener@3.5’) 102dB
Ceiling Ht: 9’ Spkr Spacing: 13.5’ Max SPL @ 30W (Listener@3.5’) 101dB
Ceiling Ht: 10’ Spkr Spacing: 16’ Max SPL @ 30W (Listener@3.5’) 99dB
Ceiling Ht: 11’ Spkr Spacing: 18.5’ Max SPL @ 30W (Listener@3.5’) 98dB
Ceiling Ht: 12’ Spkr Spacing: 21’ Max SPL @ 30W (Listener@3.5’) 97dB
Ceiling Ht: 13’ Spkr Spacing: 23.5’ Max SPL @ 30W (Listener@3.5’) 96dB
Ceiling Ht: 14’ Spkr Spacing: 25.5’ Max SPL @ 30W (Listener@3.5’) 95dB
