Description
The SM500i-II-WX is a 5.25 inch coaxial surface-mount speaker designed to deliver consistent coverage and reliable low-end response. It pairs a polypropylene woofer and a titanium tweeter on SoundTube’s BroadBeam waveguide to provide smooth on- and off-axis dispersion. The unit is weatherized and built to perform in both indoor and severe outdoor conditions.
Key features include a BroadBeam waveguide tweeter system for consistent dispersion up to 10 kHz and a six-position tap selector for 25/70.7/100 volt operation or transformer bypass. The speaker employs a 5.25 inch polypropylene woofer and a 1.0 inch convex titanium tweeter with FerroFluid cooling to maintain clarity at higher output. Stainless steel hardware and a powder-coated aluminum grille enhance long-term durability in exposed installations.
Performance specifications support demanding commercial audio applications – nominal impedance is 4 ohm, sensitivity is 86.0 dB at 2.83V/1 m and the -10 dB bandwidth extends down to 60 Hz. Power handling is rated at 75 W RMS continuous with 150 W program capability and a maximum SPL of 102 dB at 1 m. Coverage is engineered for even area coverage with averaged 2 to 10 kHz dispersion of 100° horizontal by 100° vertical.
Connectivity is handled via a four-pin 5.08 mm Euroblock for individual or daisy-chain wiring and a six-position rotary tap switch for common line-voltage options. A transformer bypass position supports direct 4 ohm amplifier connections. The included Stealth bracket system and security knob enable unlimited directional aiming while reducing tampering after installation.
This model is well suited to retail, hospitality, transit and outdoor amenity zones where weather resistance and consistent coverage are essential. It provides intelligible voice reproduction and music playback in environments that require surface mounting and directional aiming. The SM500i-II-WX balances low-frequency response and controlled high-frequency dispersion to serve background and foreground foreground audio needs.
Installation is straightforward: the low-profile enclosure and Stealth bracket keep the speaker close to the mounting surface while permitting vertical and horizontal pivoting for precise aiming. The injection-molded glass-fiber reinforced ABS enclosure and stainless fasteners provide corrosion resistance and mechanical rigidity. UL 1480 (UEAY) is planned and custom color finishes are available to integrate with architectural requirements.
