APPENDIX A: MEYER SOUND WEATHER PROTECTION
WEATHER PROTECTION COMPONENTS
Standard Weather Protection
Meyer Sound designs toward an IP rating of IPX4 (see "IP
Ratings" on page 41) for Standard Weather Protection,
which includes the following components:
• Wood treatment—Prior to cabinet manufacturing, the
raw wood receives a special treatment that penetrates
and stabilizes the wood fibers to withstand a wide range
of temperatures and exposure to extreme humidity.
• Cabinet finishing—The assembled cabinets receive a
highly impervious finish that includes a sealing primer
and a finishing topcoat. The coatings are applied on both
surfaces, with one coat on the interior and two on the
exterior. The final step is a two-part modified acrylic
urethane similar to that used in military applications.
• Driver treatment—All cone drivers are coated with a
water-resistant sealant.
• Exterior protection—Grille frames are coated to resist
corrosion, and all components that mount to the cabinet
use custom gaskets and stainless steel fasteners.
• Removable rain hood—The rain hood is designed to
shield connectors even in wind-driven rain.
INSTALLATION PRACTICES
Meyer Sound assumes normal and accepted installation
practices are used when installing Meyer Sound
Loudspeakers outdoors. Deviation from such practices may
cause weather protection to be ineffective and void the
warranty for the loudspeaker.
Examples of unacceptable and acceptable installation
practices include:
• Loudspeakers installed outdoors should not face
upward.
• Loudspeakers with a rain hood should be installed in
such a way that the rain hood opening is not facing any
direction but down.
• Meyer Sound-supplied rigging components should not
be modified (for example, by drilling additional holes in a
MUB for mounting to a wall). When an installer/integrator
modifies a Meyer Sound supplied rigging component to
support their installation method, it is considered
compromised and out of warranty.
• All loudspeaker cabling must be installed with a
"drip-loop" or equivalent method to ensure that rain/
water is NOT wicked toward the loudspeaker.
40
If in doubt about an installation method, contact Meyer
Sound Technical Support for assistance.
Always discuss the environmental conditions of your Meyer
Sound installation with your Sales Manager, and verify the
availability of Weather Protection for your selected
loudspeaker models. The Sales Manager, together with
Technical Support, will verify the appropriate level of
weather protection for the loudspeakers and related rigging
hardware.
