SoundTube SM82-EZ-II-WX 8″ 2-Way Extreme Weather Outdoor Surface Mount Speaker

The SoundTube SM82-EZ-II-WX is a high-efficiency 8″ 2-way outdoor surface mount speaker engineered for the most demanding extreme weather environments. Rated IP65, it combines a dedicated 8-inch polypropylene woofer with an offset 1-inch aluminum dome tweeter and waveguide to deliver up to 106 dB max SPL making it equally at home pumping foreground music at a resort pool deck or providing clear voice paging in a covered parking structure. Part of the SM-EZ Economical Surface Mount series, the SM82-EZ-II-WX delivers premium weatherproof audio without the complexity of high-end custom installs.

The SM82-EZ-II-WX uses a 64-watt low-insertion-loss transformer with a six-position rotary tap switch supporting 25V, 70.7V, and 100V distributed audio systems, as well as a direct 8-ohm bypass making it flexible for virtually any commercial AV infrastructure. A proprietary tool-free Stealth mounting bracket with a direct-drive cam-wedge allows precise aiming up to 90 in a single direction, dramatically reducing installation time on tall or difficult mounting surfaces. Weather Guard technology uses dual-layer hydrophobic material behind the powder-coated aluminum grille to keep moisture away from all internal components.

The speaker’s 2nd-order crossover network at 2.5 kHz ensures clean handoff between the woofer and tweeter, delivering a smooth 90 Hz22 kHz frequency response (3 dB). The polystyrene ported enclosure is reinforced to handle thermal cycling, UV exposure, and salt-air environments. A port plug is included: remove it indoors for enhanced bass output; keep it plugged outdoors to maintain IP65 integrity.

Certifications include CE, IP65, RoHS, and UL1480A. Included accessories cover a back cover, mounting hardware, port plug, safety cable, and wire gland everything needed for a code-compliant outdoor installation. Available in black (SM82-EZ-II-WX-BK) and white (SM82-EZ-II-WX-WH).
