Description
The SM52-EZ-WX-WH is a compact surface-mount full-range loudspeaker designed for weather-exposed environments. It delivers clear wideband audio from 80 Hz to 20 kHz while maintaining a rugged exterior that withstands outdoor conditions. The design balances durability and acoustic performance for commercial audio systems.
Key features include SoundTube WX Weather Guard technology that uses a dual-layer hydrophobic material in the grille to repel moisture and protect internal components. The speaker uses a 133 mm (5.25 in) polypropylene woofer paired with a 25 mm (1.0 in) soft dome tweeter to provide balanced tonal response. An easy-access six-position tap switch supports 25 V / 70.7 V / 100 V distributed audio systems and an 8 ohm transformer bypass for direct low-impedance connection.
Performance specifications support professional installation requirements – the SM52-EZ-WX-WH produces up to 105 dB SPL at 1 m and has an 86.0 dB sensitivity rating. Power handling is rated at 75 W RMS and the nominal impedance is 8 ohm. Coverage is approximately 100 degrees horizontal by 100 degrees vertical for broad area distribution.
Connectivity is handled via a ceramic terminal strip and a low-insertion-loss 32-watt transformer for consistent level matching in constant-voltage systems. The unit is UL 1480 (UEAY) approved and conforms to industry audio distribution standards for safety and reliability. The powder-coated stainless steel grille and corrosion-resistant enclosure support long-term outdoor operation.
This speaker is suited for outdoor dining areas, retail frontage, amusement venues, and other environments requiring weatherproof distributed audio. It provides clear voice and music reproduction across typical program material and integrates into 25 V / 70.7 V / 100 V systems or standard 8 ohm amplifier outputs. The compact footprint and wide coverage make placement flexible for both foreground and background music use.
Installation is simplified by a pre-mountable surface-mount bracket that facilitates quick alignment and mechanical support – the bracket design allows separation of mounting and wiring tasks. The grille’s hydrophobic treatment and powder coat finish extend service life and reduce maintenance. Overall build quality emphasizes field serviceability and long-term reliability in exposed installations.
