Install Instructions For:

Unpack speaker and mounting hardware.
Choose a secure mounting surface with sufficient strength to reliably hold the speaker. The speaker may be mounted in either the vertical or the horizontal position with the same U-bracket.
Mount u-bracket with clamping slots pointing upward. Securely fasten mounting bracket and safety cable to surface (user must supply fasteners).
Note: The safety cable will attach to the U-bracket clamping screw on one side of the cabinet.
If being installed per EN54-24 regulations or in instances where a water tight strain relief bushing is neces-sary, attach the included strain relief bushing to the back plate. If it is not required, skip this step.
Run signal wires through cstrain relief bushing then connect to ceramic terminal strip. Two + (plus) and two -(negative) connectors are provided for daisy chaining.
Select the tap position by rotating the rotary switch located on the back of the speaker to desired setting. The switch is preset to the maximum tap setting in 70.7 V mode (32W for the SM52-EZ[-WX] and 64W for the SM-82-EZ-II[-WX]).
Install back plate and secure with included fasteners.
Select desired location for safety cable and remove the U-bracket screw from that side. Attach safety cable to the clamping screw and reinstall loosely.
Tilt speaker 45º (grille up) and slide on to bracket.
Aim speaker and tighten u-bracket screws. Once tightened down, place the screw caps on the screws. Done!

Port protection for SM-EZ

To enhance protection of internal components from humidity and other potentially corrosive elements, use provided port plug to seal enclosure. Use RTV silicone around edge of the port plug for increased protection. Note: WX versions will come with the port plug pre-installed.

SM82-EZ-WX, SM52-WX

To make this unit weather extreme rated (WX) you will need to locate and discard the bracket that came in the box with the loudspeaker. WX units come with a separate stainless steel mounting bracket that will be used instead.
To make this unit weather extreme rated (WX) the port plug supplied in the box will need to be installed. Remove the grill by taking out the screws located around the edges. The grill should come off easily. Push port plug into hole on baffle and re-install grill. Note: RTV silicone can be used on the port plug for increased protection.

Description

The SM52-EZ-WX is a cost-effective, high-efficiency surface-mount loudspeaker for distributed or 8 Ω applications. The SM52-EZ-WX is designed for extreme weather resistance is rated for high levels of protection against both water and dust. The SM52-EZ-WX incorporates a dedicated 5.25” polypropylene woofer and an offset 1” soft dome tweeter with waveguide to deliver superb intelligibility for background to foreground music and messaging (up to 100 dB max. SPL). The SM52-EZ-WX uses a 32 W low-insertion loss transformer and a six-position tap switch with a transformer bypass position. Mounting for the SM52-EZ-WX includes a pre-mountable U-bracket for fast, secure installation and easy division of labor.

Features

The SM52-EZ-WX is a cost-conscious, weather resistant, surface-mount loudspeaker.
BroadBeam Ring™ technology for midrange clarity and ultra-wide off-axis performance up to 10 kHz for maximum coverage area per speaker.
One 5.25” (133 mm) polypropylene woofer and one 1” (25.4 mm) soft dome tweeter.
Extreme weather resistance with IP65 ingress protection rating allows use in challenging outdoor conditions.
83 dB average sensitivity offers high output capabilities and reduced amplification costs.
Easy access, six-position selectable tap switch for 25, 70.7, and 100 V applications with transformer bypass position.
