Weather Protection
EAW’s weather protection process is proven day after day in some of the harshest climates on Earth Based on decades of experience developing long-term solutions for outdoor applications, EAW employs several different weatherization processes for permanent installation and touring loudspeakers EAW products are continually improved. All specifications are subject to change without notice and may vary by product. WP (Weather Protection) Any product bearing the –WP designation (i.e. QX544i-WP or MK5396i-WP) employs the following measures to minimize the impact of rain, sleet, snow, and moisture. Note: Specific weather treatments vary per model.
Touring
Designed for life on the road, EAW’s touring products include corrosion-
resistant hardware components, treated cones, synthetic grille foam, and other
features to withstand temporary rain, wind, dust, and/or high heat
during events. For sustained outdoor use, EAW offers WP versions of many
touring products (such as the KF740P-WP).
IP Rating Qualification
The IP Code, International Protection Marking, IEC standard 60529, classifies and rates the degree of protection provided against intrusion (body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC) and is broken down in the following way, whereby a given assembly is classified by a four-character rating:
IP[ x1 ] [ x2 ]
- x1– Refers to solid particle protection
- x2– Refers to liquid ingress protection
EAW stands by its weather-protection processes. Based on years of experience, EAW products are designed with materials and processes that have been tested to provide the following IEC protection rating per IEC 60529 IP66 if ordered with optional Stainless Steel mesh. Requires that supplied weather protection shields are used. These enclosure equivalence ratings are determined in configurations with the front of the enclosure level, or at negative tilt levels. WP process will achieve a minimum rating of IP54. Non-WP EAW production-grade touring products, including Anna, Anya, Otto, JF series, KF series, Microwedge, and SB series, have been tested beyond standard specifications in real-life scenarios. These products have a history of surviving harsh weather conditions including extreme cold, heat, and hurricanes.
Installation and Maintenance
- EAW Weather-Protected Loudspeaker Systems are intended to withstand direct exposure to the weather.
- However, any steps that can be taken to minimize this exposure will maximize the life of the loudspeaker system. These include:
- Select mounting locations that provide some level of shielding from the weather. Examples include balcony overhangs, etc.
- If a dedicated loudspeaker system support structure is to be provided, a simple roof construction can help reduce exposure to the loudspeakers to direct moisture
- Aim loudspeaker systems in a manner consistent with EAW’s recommended use. This will ensure that weather-protection features are properly oriented
- Never submerge weather-protected loudspeakers
Maintaining Weather-Protection Features
Care must be taken during installation or maintenance to avoid any measures
that could compromise weather-protection features. Of particular concern are:
Mounting Hardware
Each product is shipped with a bolt in each available mounting point. Each bolt is sealed with a non-hardening, waterproof, non-locking thread sealant. Any bolts removed during the installation process must be replaced, as an exposed bolt hole provides an opening into the interior of the loud-speaker enclosure. Any bolts removed and replaced during installation must be resealed. In no case should any type of hardware be used to mount the loudspeaker system except for structurally approved stainless-steel hardware which mates into factory-installed mounting points integral to the loudspeaker system.
Fiberglass Shell
Each loudspeaker system must be handled carefully during the installation to
avoid cracking or perforating the exterior fiberglass shell. In no case should
anything be attached to the loudspeaker shell, except using structurally
approved stainless-steel hardware which mates into the factory-installed
mounting points integral to the loudspeaker system.
NOTE: The warranty on Weather-Protected loudspeakers will be voided if
reasonable care is not taken in selecting mounting locations. Locations that
channel or direct water onto installed loudspeaker systems will void the
warranty. Submersion of loudspeakers will void the warranty
Weather Protection
Maintaining Weather-Protection Features (continued)
Grilles
Grilles may be factory-attached using screws of varying lengths. Use care when
reattaching the grille to ensure that all hardware is returned to the correct
locations.
Access Hatches
Hatches that are removed for any reason must be replaced and sealed with a
non-hardening, waterproof, UV-stable sealant suitable for use over the
temperature range typical for your geographical location. The sealant must be
compatible with the surface being sealed to ensure proper adhesion. Hardware
used to secure hatches must be sealed with a non-hardening, non-locking thread
sealant.
Input Cover Plates
All cover plates must be in place after connections to the loudspeaker system
have been made. The conduit should be connected to cover plates using
waterproof fittings. Bolts securing cover plates1 must be sealed
with a non-hardening, non-locking thread sealant.
Drivers/Transducers
EAW drivers/transducers intended for use in Weather-Protected systems are
designed specifically for outdoor applications. Failed units should only be
repaired/replaced with factory-authorized parts. When contacting the EAW
Service Department, be sure to notify service personnel that the replacement
part is for use in a WeatherProtected system
Routine Inspection
While installed, loudspeakers should be periodically examined and tested to
maintain performance and safety. Two main areas for inspection are Acoustical
Performance and Structural Integrity. Some of the main inspection points are
as follows:
Acoustical Performance
Loudspeakers should be individually checked by an experienced sound system
professional to verify that all drivers are operational. Please contact the
system installer or EAW for further assistance or guidance with testing.
Structural Integrity
Loudspeakers should be periodically examined for signs of physical damage. Specifically, the following should be checked:
- Damage to loudspeaker due to vandalism
- Deterioration of mounting hardware due to rust or corrosion
- Damage to weather-protection features due to improper installation or maintenance
- Any other deterioration of the loudspeaker system including loosening of parts, accessories, or attachments which could fall or cause injury
Failure of any type should be immediately reported to the system installer or Eastern Acoustic Works. If you need assistance, please contact us at +1 508-234-6158 or toll-free at +1 800-992-5013. We will be happy to provide more detailed information on testing, maintenance, installation, or any other aspect of your loudspeaker system.
