Atlas Sound SM52T-WH – 5.25" 2-Way Weather Resistant Speaker Pair White

Product Overview

The Atlas Sound SM52T-WH is a pair of 5.25" 2-way weather-resistant surface-mount speakers from the Strategy Series, designed for distributed audio installations in indoor and outdoor commercial environments. Each speaker includes a 30-watt 70.7V/100V transformer with screwdriver-selectable taps and an 8-ohm bypass, making the SM52T-WH a direct-connect solution for 70V commercial sound systems in restaurants, retail spaces, houses of worship, and recreation facilities. Built from UV-resistant talc-impregnated polypropylene with powder-coated aluminum grilles and all-brass hardware, these speakers are constructed to withstand 100 hours of salt spray per ASTM B117 — the standard for corrosion-resistant construction used in coastal and humid environments. Priced and sold as a pair with C-brackets included.

Product Description

The SM52T-WH Strategy Series speakers are engineered for distributed sound applications where weather exposure, audio consistency, and installation versatility all matter simultaneously. The 5.25" polypropylene woofer and 1" ferrofluid-cooled titanium dome tweeter provide a 85 Hz to 20 kHz frequency response with 90 dB sensitivity — a practical combination for background music and speech reinforcement across the SMT52T's intended coverage range.

The high-frequency section uses AtlasIED's TRX Control WaveGuide, which is a constant-directivity style waveguide system that produces smooth, even 90° horizontal by 90° vertical coverage in both vertical and horizontal cabinet mounting orientations. This symmetrical HF dispersion means a pair of SM52T speakers can be mounted in either portrait or landscape orientation on the same system without creating coverage mismatches. High-frequency driver protection is handled by the AtlasIED PolyGuard circuit, which diverts damaging transient signals away from the tweeter before they can cause driver failure.

The 30-watt 70.7V/100V transformer includes taps at 0.94, 1.9, 3.7, 7.5, 15, and 30 watts, selectable via a sealed screwdriver-accessible switch on the rear of the cabinet. An 8-ohm bypass is also available. The tongue-in-groove cover with rubber wire exit grommet protects the input and transformer assembly from moisture — a detail that matters in outdoor and humid environments where uncovered terminals corrode over time. The C-bracket accepts a 5/8"-27 threaded adapter for mounting on AtlasIED microphone stands for near-field live sound applications, and rear-panel 2-3/8" OC brass inserts accommodate Omnimount brackets. All 1/4"-20 hardware inserts allow substitution with vandal-proof or one-way security hardware where required. The enclosure can be painted to match architectural finishes.

Key Features

• Weather-Resistant Construction (ASTM B117 Rated) — UV-resistant talc-impregnated polypropylene enclosure, powder-coated aluminum grilles, and all-brass hardware survive 100 hours of salt spray testing for reliable performance in humid, coastal, and outdoor covered environments.
• 30-Watt 70.7V/100V Transformer with 8Ω Bypass — Screwdriver-selectable taps (0.94, 1.9, 3.7, 7.5, 15, 30W) and an 8-ohm bypass enable direct connection to 70V systems or low-impedance amplifiers without additional wiring changes.
• TRX Control WaveGuide HF System — Constant-directivity waveguide provides 90° x 90° even coverage in both vertical and horizontal mounting orientations for consistent system response regardless of cabinet position.
• PolyGuard HF Protection Circuit — Diverts damaging transient signals away from the titanium dome tweeter to prevent thermal and mechanical driver failure during live and amplified audio events.
• 1" Ferrofluid-Cooled Titanium Dome Tweeter — Ferrofluid cooling and titanium construction provide extended HF response and thermal management for sustained commercial-grade operation.
• Sealed Input / Transformer Cover with Rubber Grommet — Tongue-in-groove moisture cover with rubber wire exit grommet protects terminals and transformer switch from water intrusion in outdoor and humid installations.
• Versatile C-Bracket with 5/8"-27 Thread and 1/4"-20 Inserts — Included C-bracket supports wall/surface mounting, microphone stand mounting, and Omnimount brackets, with 1/4"-20 inserts for security hardware substitution.
• Paintable Enclosure — Cabinet can be painted to match any architectural finish for installations where speaker visibility must be minimized.
• Five-Year Warranty — Strategy Series speakers carry a 5-year limited warranty, one of the longer standard warranties in the commercial surface-mount speaker category.

Typical Applications

• House of worship
• Commercial meeting space

• Training room

Technical Specifications

Frequently Asked Questions

Q: Are these sold individually or as a pair?

A: The SM52T-WH is priced and sold as a pair. Two speakers and two C-brackets are included in each order.

Q: Can the SM52T-WH be used outdoors?

A: Yes, with the caveat that the speakers should not be exposed to direct precipitation. The weather-resistant construction (ASTM B117 100-hour salt spray rated) handles humidity, UV exposure, and covered outdoor environments. Direct rain or standing water exposure should be avoided.

Q: What distributed voltage systems is the transformer compatible with?

A: The internal transformer supports both 70.7V and 100V line-level distributed audio systems, with screwdriver-selectable taps from 0.94 to 30 watts and an 8-ohm bypass for low-impedance amplifier use.

Q: Can the SM52T-WH be mounted horizontally?

A: Yes. The TRX Control WaveGuide HF system provides a symmetrical 90° x 90° coverage pattern, which is equal in both orientations. The speaker can be mounted vertically or horizontally without altering the effective coverage pattern.

Q: What is the difference between the SM52T-WH (white) and SM52T-B (black)?

A: The SM52T-WH and SM52T-B are identical in all technical specifications. The only difference is enclosure color — white for the WH variant and black for the B variant.

Q: What is the warranty on the SM52T-WH?

A: The SM52T-WH carries a 5-year limited warranty from Atlas Sound. Contact Creation Networks or AtlasIED for warranty claim procedures.
