Atlas Sound SM52T-B – 5.25" 2-Way Weather Resistant Speaker Pair Black

Product Overview

The Atlas Sound SM52T-B is a pair of 5.25" 2-way weather-resistant surface-mount speakers from the Strategy Series, engineered for commercial distributed audio in retail stores, restaurants, cafes, recreation centers, houses of worship, and indoor/outdoor installations requiring long-term environmental durability. Each speaker includes a 30-watt 70.7V/100V transformer with screwdriver-selectable taps and an 8-ohm bypass, allowing direct integration into any standard 70V commercial audio system without additional hardware. The UV-resistant polypropylene enclosure, powder-coated aluminum grille, and all-brass hardware are certified to 100 hours of salt spray per ASTM B117, delivering corrosion resistance in humid and covered outdoor environments. Sold and priced as a pair with C-brackets included.

Product Description

The SM52T-B Black is the darker-finish variant of Atlas Sound's SM52T Strategy Series surface-mount loudspeaker, sharing identical technical specifications with the SM52T-WH but finished in black to suit architectural contexts where a white speaker would be visually prominent. The 5.25" polypropylene woofer and 1" ferrofluid-cooled titanium dome tweeter provide 90 dB sensitivity and full-range reproduction from 85 Hz to 20 kHz across a 100-watt RMS power rating, handling both background music and speech reinforcement duties in a single compact enclosure.

AtlasIED's TRX Control WaveGuide provides constant-directivity 90° x 90° high-frequency coverage in both vertical and horizontal mounting positions. This symmetrical dispersion pattern is particularly useful in multi-zone distributed systems where speakers may be installed in different orientations on different surfaces — coverage characteristics remain consistent regardless of how the cabinet is positioned. The PolyGuard HF protection circuit diverts damaging transients away from the tweeter, preventing failure during system events such as amplifier clipping or signal faults.

The 30-watt 70.7V/100V transformer's sealed tap-selector switch is accessible via screwdriver through the rear of the cabinet without opening or removing any covers. The tongue-in-groove moisture cover with rubber wire exit grommet keeps the terminal block and transformer switch dry in humid and covered outdoor locations. The C-bracket includes a 5/8"-27 threaded hole for microphone stand mounting in near-field live sound applications, and 2-3/8" OC brass rear-panel inserts accept Omnimount brackets. All mounting hardware uses standard 1/4"-20 inserts, allowing substitution with vandal-proof or one-way security hardware in high-traffic venues.

Key Features

• Weather-Resistant Construction (ASTM B117 100-Hour Salt Spray) — UV-resistant polypropylene enclosure, powder-coated aluminum grille, and all-brass hardware provide verified corrosion resistance for covered outdoor and humid environment installations.
• 30-Watt 70.7V/100V Transformer with 8Ω Bypass — Screwdriver-selectable taps (0.94, 1.9, 3.7, 7.5, 15, 30W) allow precise level setting within 70V systems; 8-ohm bypass enables use with standard low-impedance amplifiers.
• TRX Control WaveGuide HF System — Constant-directivity 90° x 90° coverage in both vertical and horizontal mounting orientations ensures consistent high-frequency distribution regardless of cabinet position.
• PolyGuard HF Driver Protection — Diverts damaging transient signals away from the titanium tweeter, reducing the risk of HF driver failure during normal and extended commercial system operation.
• 1" Ferrofluid-Cooled Titanium Dome Tweeter — High-temperature ferrofluid and titanium dome construction provide extended frequency response and thermal management for sustained output levels.
• Sealed Moisture Cover with Rubber Wire Grommet — Tongue-in-groove cover over the terminal block and transformer switch prevents water intrusion in humid and covered outdoor environments.
• Versatile C-Bracket (5/8"-27 Thread, Omnimount, 1/4"-20 Inserts) — Included bracket supports wall mounting, microphone stand mounting, and Omnimount systems, with 1/4"-20 inserts for optional security hardware.
• Paintable Enclosure — Polypropylene cabinet accepts paint for blending into any architectural color scheme.
• Five-Year Limited Warranty — Strategy Series coverage provides long-term warranty protection for permanent commercial installations.

Typical Applications

• House of worship
• Commercial meeting space

Frequently Asked Questions

Q: Are these sold individually or as a pair?

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

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

A: Both models are technically identical. The SM52T-B is finished in black and the SM52T-WH is finished in white. Select the color that best suits the installation environment's architectural finish.

Q: Can the SM52T-B be used outdoors?

A: Yes, for covered outdoor installations. The enclosure is rated to 100 hours of salt spray per ASTM B117, handling humidity, UV exposure, and moderate environmental conditions. Direct rain or water immersion should be avoided.

Q: What 70V tap settings are available?

A: The 30-watt transformer provides taps at 0.94, 1.9, 3.7, 7.5, 15, and 30 watts, all selectable by screwdriver via a sealed switch on the rear of the cabinet. An 8-ohm bypass is also provided for low-impedance amplifier use.

Q: Can the SM52T-B be painted?

A: Yes. The polypropylene enclosure accepts paint, allowing the speaker to match any architectural wall or ceiling color.

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

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