**PACK OF 2** EN54-24 Certified 4" 2-Way All Weather Speaker

This pack-of-two listing supplies two AtlasIED SM42TEN-WH loudspeakers in a compact 4-inch, 2-way format. Each loudspeaker is a surface-mount model described as weather-resistant and protected by Poly Guard™. A 16-watt 70.7/100V transformer supports compatible distributed speaker systems, while an 8-ohm bypass provides another integration option. EN54-24 certification makes the SM42TEN-WH suitable for projects that specifically require loudspeakers certified to that standard.

Ideal Use Cases

This pair fits installations requiring compact, surface-mounted loudspeakers with weather resistance and EN54-24 certification. The 70.7/100V transformer supports projects designed around transformer-based speaker lines, and the selectable power taps offer several choices for configuring each loudspeaker within the system. The 8-ohm bypass also accommodates installations designed for that impedance. Because the listing includes two speakers, it provides a matched pair for applications requiring coverage from two mounting positions.

Why Choose This Model

The SM42TEN-WH combines several specified capabilities in one enclosure: a 4-inch 2-way design, weather-resistant construction, Poly Guard protection, EN54-24 certification, and both transformer and 8-ohm operating options. Its transformer provides 3-, 5-, 8-, and 16-watt power taps for 70.7/100V systems. This range lets an installer select from the available settings according to the requirements of the connected system. The 8-ohm bypass extends compatibility beyond transformer operation without requiring a different speaker model.

Installation and Integration

Each SM42TEN-WH is designed for surface mounting. The enclosure measures 7 inches high, 5 inches wide, and 5 15/16 inches deep, equivalent to 17.78 x 12.7 x 15.03 cm. These stated dimensions make it possible to review mounting-space requirements before installation. The provided shipping-weight specification is 5.00 lbs, or 2.27 kg. During system planning, the selected 3-, 5-, 8-, or 16-watt tap should correspond to the intended 70.7/100V configuration. For an 8-ohm system, the specified bypass provides the appropriate alternative operating mode.

Performance Highlights

The stated frequency response is 115Hz to 16kHz. Standard sensitivity is rated at 88dB, while the separately supplied EN54-24 sensitivity specification is 67dB. The integral transformer is rated at 16 watts and provides four selectable power taps. Together, these published values give system designers concrete frequency, sensitivity, power, and impedance information for evaluating the speaker against project requirements. The 2-way configuration and 4-inch format are consistent across both speakers included in this listing.

What Makes It Different

The defining feature set is the combination of EN54-24 certification, weather-resistant construction, Poly Guard protection, and flexible electrical integration. Rather than limiting installation to a single transformer setting, the SM42TEN-WH provides four specified tap levels and an 8-ohm bypass. Its surface-mount form factor keeps the installation approach straightforward, while the compact enclosure dimensions help when available mounting space must be considered. The pack-of-two format also groups two matching SM42TEN-WH loudspeakers under one SKU.

Final Assessment

This AtlasIED pair is a focused option for projects that call for 4-inch, 2-way, weather-resistant surface-mount speakers with EN54-24 certification. The 16-watt 70.7/100V transformer, multiple power taps, and 8-ohm bypass provide clearly defined integration choices. Published performance includes an 88dB sensitivity rating and a 115Hz to 16kHz frequency response. AtlasIED provides a warranty period of 60 months from the date of purchase.
