Atlas Sound SM63T-B – 6.5" 2-Way 70V Weather Resistant Speaker Pair (Black)

Product Overview

The AtlasIED SM63T-B is a commercial-grade 6.5-inch 2-way weather-resistant loudspeaker system with an integrated 32-watt 70.7V/100V line matching transformer, sold and priced as a pair in black. Designed for indoor and outdoor distributed audio applications, this surface-mount 70V speaker delivers clear, even 120-degree horizontal and vertical coverage with a UV-resistant polypropylene enclosure, powder-coated aluminum grille, and all-brass hardware — making it a durable choice for commercial sound reinforcement in demanding environments.

Product Description

The SM63T-B is part of the AtlasIED SM Series Strategy Series of environment-resistant surface-mount loudspeakers, engineered for commercial sound reinforcement applications where weather resistance, intelligibility, and long-term durability are required. The two-way system combines a highly efficient 6.5-inch polypropylene woofer with a 1-inch FerroFluid-cooled titanium dome tweeter, and the AtlasIED TRX Control WaveGuide high-frequency director optimizes vocal and musical clarity with smooth, even coverage across the 120-degree horizontal and 120-degree vertical pattern. The symmetrical high-frequency section provides equal coverage in both vertical and horizontal cabinet mounting positions.

The integrated 32-watt 70.7V/100V line matching transformer includes screwdriver-selectable tap positions at 4, 8, 16, and 32 watts with an 8-ohm bypass, accessed via a sealed switch on the rear panel. This tap selection approach is practical for installers working in 70V distributed audio systems, allowing power distribution to be set at the speaker without running back to the amplifier. The AtlasIED PolyGuard protection circuit diverts damaging transient signals away from the tweeter, extending driver life in high-SPL applications.

The enclosure is constructed from UV-resistant, talc-impregnated polypropylene injection molding and has passed a 100-hour salt spray test per ASTM B117, confirming suitability for year-round outdoor use in coastal and harsh environments. The included color-matched C-bracket enables easy horizontal or vertical wall mounting on virtually any surface and features a standard 5/8-27 thread for microphone stand mounting. OMNIMOUNT-compatible 2-3/8-inch OC brass inserts are provided on the rear, and all hardware inserts are standard 1/4-20 for easy substitution of vandal-proof or security fasteners. The two-conductor barrier strip accepts up to two #14 AWG conductors per terminal. The SM63T-B is UL 1480A listed with a 5-year warranty, and the enclosure can be field-painted to match any architectural finish.

Key Features

Frequently Asked Questions

Q: Is the SM63T-B sold as a single speaker or a pair?

A: The SM63T-B is priced and sold as a pair. The listed price includes two speakers with their mounting brackets.

Q: How do I select the power tap on the SM63T-B for a 70V system?

A: A sealed rotary switch on the rear panel of each speaker allows screwdriver selection of the 70.7V/100V transformer tap. Available positions are 4, 8, 16, and 32 watts, plus an 8-ohm bypass for direct low-impedance connection. Select the tap matching your system design calculations for power distribution.

Q: Is the SM63T-B suitable for outdoor installation?

A: Yes. The SM63T-B is constructed with UV-resistant, talc-impregnated polypropylene and has passed a 100-hour salt spray test per ASTM B117, confirming weather resistance for year-round outdoor use. Avoid direct precipitation exposure where possible and use appropriate mounting hardware for the installation surface.

Q: Can the enclosure be painted to match a building's exterior or interior color scheme?

A: Yes. The SM63T-B enclosure can be field-painted to match architectural color requirements. Use paint compatible with polypropylene and avoid blocking the grille perforations.

Q: What mounting options are available for the SM63T-B?

A: The included color-matched C-bracket provides vertical or horizontal surface mounting on any wall or structure. A standard 5/8-27 threaded hole on the C-bracket accommodates microphone stand mounting. Rear OMNIMOUNT-compatible brass inserts provide an alternative mounting point for OMNIMOUNT bracket systems.

Q: Is a white version of the SM63T available?

A: Yes. The SM63T is also available in white (SM63T-W) for installations requiring a light-finish speaker.

Q: What is the warranty on the SM63T-B?

A: The AtlasIED SM63T-B carries a 60-month (5-year) limited warranty from date of purchase.
