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

Product Overview

The Atlas Sound SM82T-B is an 8-inch 2-way all-weather surface mount speaker in black finish, designed for year-round indoor and outdoor commercial audio installations with 70V/100V distributed system compatibility. The built-in 60-watt 70.7V/100V transformer with screwdriver-selectable taps integrates directly into distributed audio runs, and the UV-resistant polypropylene enclosure passes the 100-hour salt spray test per ASTM B117. With its black finish, the SM82T-B is suited for installations where a low-profile, dark aesthetic is required — including dark-ceiling venues, outdoor entertainment areas, and commercial spaces where visual discretion is prioritized.

Product Description

The SM82T-B is built around an 8-inch HYCONET-treated woofer and a 1-inch exit titanium high-frequency compression driver, delivering a frequency response of 65Hz to 20kHz with 92dB average sensitivity. The AtlasIED TRX WAVEGUIDE™ constant-directivity wave guide provides 65-degree horizontal by 65-degree vertical symmetric coverage, maintaining consistent dispersion in both vertical and horizontal cabinet mounting positions. This is a practical advantage when installation geometry forces non-standard orientation. The POLYGUARD™ circuit protects the compression driver from transient signal overloads that can cause premature failure in commercial systems driven at sustained high levels. The 60-watt 70.7V/100V transformer includes an 8-ohm bypass and is adjusted via a sealed screwdriver switch at the rear of the cabinet, with tap settings at 1.9, 3.7, 7.5, 15, 30, and 60 watts. The enclosure uses UV-resistant talc-impregnated polypropylene molding with powder-coated aluminum grille and full brass hardware inserts, all in black. The zinc chromate plated and powder-coated C-bracket is included for surface mounting in vertical or horizontal orientation, with a 0.59-inch through hole supporting optional microphone stand placement for portable near-field use. The speaker accepts up to 14AWG cable at its two-pole barrier strip input, and the sealed tongue-in-groove input cover with rubber grommet provides moisture protection. All 1/4-20 mounting inserts accept standard vandal-resistant security hardware without modification, making the SM82T-B appropriate for high-traffic or public-access installations.

Technical Specifications

Frequently Asked Questions

Q: What is the difference between the SM82T-B and SM82T-WH?

A: The two models are identical in performance specifications. The SM82T-B ships in black with color-matched hardware and grille; the SM82T-WH ships in white. Choose based on the installation environment’s aesthetic requirements.

Q: Can the SM82T-B be used outdoors?

A: Yes. The UV-resistant polypropylene enclosure and corrosion-resistant hardware pass the 100-hour ASTM B117 salt spray test. Avoid direct precipitation exposure; use covered or sheltered mounting locations.

Q: How are the transformer taps adjusted?

A: A sealed screwdriver switch on the rear of the cabinet selects from six 70.7V/100V power taps (1.9 to 60W) plus an 8-ohm bypass. No speaker removal is required for adjustment.

Q: Does mounting the speaker sideways affect sound quality?

A: No. The TRX WAVEGUIDE HF system is symmetrical, producing the same 65°H x 65°V dispersion in both vertical and horizontal orientations.

Q: Is the SM82T-B suitable for security-sensitive installations?

A: Yes. All mounting inserts use standard 1/4-20 threads, which accept commercially available torx-head or one-way security fasteners as a direct replacement for the included hardware.

Q: What input wire gauge is supported?

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