Atlas Sound SM52T
30W, 5-1/4" Weather-Resistant 2-Way Speaker in White with 70.7V/100V Transformer


Use surface-mount Atlas Sound SM52T Series loudspeaker systems for commercial, professional and residential applications or where high-fidelity sound and weather-resistance is desired. Full-range frequency response makes these systems ideal for indoor and outdoor installation, in monaural and stereo foreground or background music systems, and for applications in boutiques/shops, restaurants/cares, leisure, recreation/sports centers and houses of worship. Multi-position, C-shaped mounting bracket and rugged construction provide optimum installation flexibility and assurance of long-term service.

NOTE: Pricing shown is per speaker; speakers are ONLY sold in pairs.

Environment-resistant SM Series loudspeaker systems offer quality sound reproduction and contemporary styling in a compact enclosure.

System components consist of a highly efficient woofer section and FerroFluid cooled, titanium dome high frequency device. Vocal and musical clarity is optimized by the mathematically conceived, advanced design of the Atlas Sound TRX Control WaveGuide high frequency director.

This design provides smooth, even sound coverage (90°H x 90°V). The high frequency section is symmetrical, for equal coverage in both vertical and horizontal cabinet mounting positions. High frequency component protection is provided by the Atlas Sound PolyGuard protection circuit.

The SM52T includes an internally mounted 30W 70.7V/100V line matching transformer with 8 ohm bypass and screwdriver adjustable tap selection for use in distributed sound applications.

To withstand the harshest environments, the new Strategy Series SM52T surface mount loudspeakers are constructed of weather resistant materials: UV-resistant, talc impregnated, polypropylene injection molded cabinets; polypropylene woofer cones; powder coated aluminum grilles and all brass hardware.

The Strategy Series speaker systems include a versatile, yet simple, C-bracket designed to provide easy vertical or horizontal installation on just about any surface. Care should be taken to ensure that the chosen fixing point is strong enough to support the SM52T. Care should also be taken to ensure that the SM52T is not exposed to direct precipitation.

A 5/8"-27 threaded hole is provided on the C-bracket to allow the SM52T series speaker to be mounted on any Atlas Sound microphone stand for near-field live sound applications. 2 3/8" OC brass inserts are also provided on the rear of the SM52T to accommodate OMNIMOUNT 25 series brackets. All inserts for mounting knobs are standard 1/4"-20 to allow easy substitution of off-the-shelf vandal-proof torx head or "one-way" hardware.

Input connectors include a two pole barrier strip with wire capture "caps" capable of accepting up to (2) #14 AWG cable. .94, 1.9, 3.7, 7.5, 15, 30 watt and 8 ohm bypass taps are screwdriver selectable via a sealed switch located near the input section on the rear of the cabinet. A tongue-in-groove cover with rubber wire exit grommet is provided to protect the input connections and transformer switch assembly from moisture. Black finish can be painted to accommodate any architectural considerations.
