Atlas Sound SM82T-WH – 8" 2-Way All-Weather Surface Mount Speaker White 60W

Product Overview

The Atlas Sound SM82T-WH is an 8-inch 2-way all-weather surface mount speaker in white finish, built for year-round indoor and outdoor commercial audio installations. Equipped with a factory-installed 60-watt 70.7V/100V transformer, it integrates directly into distributed audio systems without additional transformer hardware. The SM82T-WH targets deployments where weather resistance, consistent coverage, and 70V distributed system compatibility must coexist — including exterior building perimeters, covered outdoor venues, commercial signage areas, and covered walkways where moisture and UV exposure are ongoing concerns.

Product Description

The SM82T-WH combines an 8-inch HYCONET-treated woofer with a 1-inch exit titanium high-frequency compression driver, delivering full-range coverage from 65Hz to 20kHz. The AtlasIED TRX WAVEGUIDE system — a constant-directivity high-frequency director — provides 65-degree horizontal by 65-degree vertical coverage symmetry, ensuring equal dispersion whether the cabinet is mounted vertically or horizontally. This symmetrical HF section is a practical advantage on installations where speaker orientation is dictated by architectural constraints. The POLYGUARD high-frequency protection circuit diverts damaging transient signals away from the titanium compression driver, extending component longevity in systems that experience amplifier power spikes or program material with sharp transients. The 60-watt transformer is screwdriver-adjustable through a sealed switch near the input section, with taps at 1.9, 3.7, 7.5, 15, 30, and 60 watts for precise system tuning without removing the speaker from its mount. The enclosure is constructed from UV-resistant, talc-impregnated polypropylene with powder-coated aluminum grilles and all-brass hardware inserts, meeting the 100-hour salt spray test requirement per ASTM B117. The included zinc chromate plated and powder-coated C-bracket supports both vertical and horizontal surface mounting and includes a 0.59-inch through hole for optional microphone stand mounting in near-field live sound applications. Four 1/4-20 brass inserts on both cabinet ends accommodate OMNIMOUNT brackets for installations requiring alternative mounting geometry. All mounting hardware uses standard 1/4-20 inserts to allow vandal-resistant torx or one-way screw substitution in security-sensitive deployments. The input section includes a two-pole barrier strip with wire capture caps accepting up to 14AWG cable, and a tongue-in-groove cover with rubber wire exit grommet seals the connection area from moisture ingress.

Key Features

• 8" HYCONET-Treated Woofer — High-efficiency low-frequency driver delivers controlled bass reproduction in a compact enclosure.
• 1" Exit Titanium Compression Driver — High-output HF driver provides extended treble performance and long-term reliability compared to conventional dome tweeters.
• TRX WAVEGUIDE™ Constant Directivity HF System — Delivers 65°H x 65°V even coverage in both vertical and horizontal cabinet orientations.
• POLYGUARD™ HF Protection Circuit — Diverts transient overloads away from the tweeter, protecting the driver in high-SPL and reactive amplifier environments.
• 60W 70.7V/100V Screwdriver-Adjustable Transformer — Sealed tap switch provides six power settings for precise distributed system level control.
• All-Weather Construction — UV-resistant polypropylene enclosure, powder-coated aluminum grille, and brass hardware meet 100-hour ASTM B117 salt spray requirements.
• Symmetrical HF Dispersion — Equal coverage in vertical and horizontal mounting positions eliminates orientation-dependent response variation.
• OMNIMOUNT™ Compatible — Standard 1/4-20 brass inserts on both ends support third-party mounting bracket options.
• Vandal-Resistant Hardware Option — Standard 1/4-20 inserts accept off-the-shelf torx or one-way security hardware without modification.
• Sealed Input Cover — Tongue-in-groove cover with rubber grommet protects wiring connections from moisture in exposed installation environments.
• UL 1480 Certified — Safety listed for use in commercial and institutional fire-alarm-associated audio installations.

Technical Specifications

Frequently Asked Questions

Q: Can the SM82T-WH be installed outdoors permanently?

A: Yes. The UV-resistant polypropylene enclosure, powder-coated aluminum grille, and brass hardware are designed for year-round outdoor use. The enclosure passes the 100-hour salt spray test per ASTM B117, making it suitable for coastal and high-humidity environments. Avoid direct precipitation exposure; use covered or overhang-protected mounting positions.

Q: Does the speaker work on both 70V and 100V systems?

A: Yes. The built-in transformer supports both 70.7V and 100V distributed audio systems. Select the appropriate tap level during commissioning.

Q: Can the power tap be adjusted after the speaker is mounted?

A: Yes. The tap selector is a screwdriver-adjustable sealed switch accessible at the rear of the cabinet without removing the speaker from its mount.

Q: Does mounting orientation affect coverage pattern?

A: No. The TRX WAVEGUIDE HF system is symmetrical, providing the same 65°H x 65°V coverage whether the speaker is mounted vertically or horizontally.

Q: What wire gauge is accepted at the input terminals?

A: The two-pole barrier strip accepts up to 14AWG cable with wire capture cap connectors.

Q: Is the SM82T-WH suitable for fire-alarm-associated audio use?

A: Yes. The SM82T-WH is UL 1480 safety listed, qualifying it for use in fire-alarm associated audio systems in commercial and institutional buildings.

Q: Can I use third-party mounting brackets with this speaker?

A: Yes. The speaker includes four 1/4-20 brass inserts on both cabinet ends for OMNIMOUNT-compatible brackets, and the included C-bracket supports both surface and stand-mount configurations.
