SoundTube SM590I-II-WX 5.25″ 2-Way Extreme Weather Outdoor Surface Mount Speaker

The SoundTube SM590I-II-WX is a 5.25″ 2-way outdoor surface mount speaker from the SMi Surface Mount series, built to deliver high-output, high-clarity audio in extreme weather environments. SoundTube’s WX Weather Guard technology combining a dual-layer hydrophobic material behind the powder-coated aluminum grille with a fully sealed, ported ABS glass fiber reinforced enclosure ensures drivers and internal electronics stay dry and fully operational through rain, humidity, and temperature extremes. The IP44-rated SM590I-II-WX is designed for environments where a standard outdoor speaker would fail, but where full-size speakers would be physically intrusive.

At the heart of the SM590I-II-WX is a 5.25″ polypropylene woofer paired with a 1″ convex titanium horn-loaded tractrix tweeter, delivering 87 dB average sensitivity and up to 160W of program power handling. The patented ZeroReflection enclosure technology minimizes standing waves for accurate, distortion-free reproduction a meaningful distinction in high-SPL outdoor applications. A six-position selectable tap switch supports 25V, 70.7V, and 100V distributed systems, plus a direct 4-ohm bypass, making the SM590I-II-WX compatible with virtually any commercial or professional AV infrastructure.

Installation is handled by the SM590I-II Stealth bracket system, allowing independent vertical and horizontal pivoting so the speaker can be aimed anywhere within the installation space while maintaining a low-profile footprint close to the wall. Included accessories cover a Euroblock connector, mounting hardware, safety cable, and terminal weather boot everything needed for a code-compliant weatherproof installation. Available in black (SM590I-II-WX-BK) and white (SM590I-II-WX-WH).

Technical Specifications

Frequently Asked Questions

Q: What does the IP44 rating mean for outdoor use?
A: IP44 indicates the speaker is protected against solid objects larger than 1 mm and water splashing from any direction suitable for covered outdoor areas exposed to rain and weather, but not for direct submersion or high-pressure water jets.

Q: How does the SM590I-II-WX differ from the SM82-EZ-II-WX?
A: The SM590I is a smaller 5.25″ 2-way speaker with a horn-loaded tweeter suited for tighter spaces and medium-distance coverage. The SM82-EZ-II-WX uses a larger 8″ woofer with higher max SPL (106 dB) and IP65 rating, making it the better choice for larger areas and hose-down environments.

Q: Can this speaker be wall-mounted at an angle?
A: Yes. The Stealth bracket supports independent vertical and horizontal pivoting for precise aim in any direction from a fixed wall or ceiling mount point.

Q: What is the maximum tap wattage on 70V?
A: The maximum transformer tap is 64W at 70.7V. The total wattage of speakers connected to a single amplifier channel should not exceed the amplifier’s rated output.

Q: Is a white version available?
A: Yes. The SM590I-II-WX is available in both black (SM590I-II-WX-BK) and white (SM590I-II-WX-WH). A white grille replacement (GRL-SM500-II-WX-WH) is also available as an accessory.

Q: Where can I buy the SM590I-II-WX with design support?
A: Contact Creation Networks at for project pricing, system design assistance, and authorized SoundTube dealer support.
