The Adastra WSP25 is a 25 W weatherproof sound projector speaker designed for both indoor and outdoor announcements and background music. Ideal for commercial installations--such as transport hubs, retail spaces, public venues and industrial sites--it delivers clear, directed audio in exposed environments.
Constructed with a robust ABS injection‑moulded housing and featuring a coated steel or stainless‑steel grille and mounting bracket, the WSP25 is built to withstand harsh weather conditions. The IPX5 rating ensures resilience against water jets, making year‑round outdoor installation reliable.
The ergonomic, adjustable bracket facilitates precise aiming and stable mounting. At approximately 2 kg, the lightweight design eases installation and positioning without compromising durability.

The WSP25 delivers clear, directed sound with efficient coverage in open spaces. The 92 dB sensitivity ensures good projection even at lower power tap settings. Switching between 100 V line and low‑impedance modes provides installation flexibility. The rugged build and compact design make it ideal for installations where environmental resistance and precise audio targeting are required.
Q: Is the WSP25 suitable for salty or marine environments?
A: While it offers IPX5 water resistance and stainless‑steel mounting, for coastal or salt‑laden air environments, consider routine inspection and optional corrosion‑resistant fixings.
Q: Can this be used with a standard low‑impedance amplifier?
A: Yes - its internal transformer can be bypassed to operate at 8 Ω, delivering 25 W from a compatible amplifier.
Q: Can I mount it indoors? Is sound directional?
A: Yes. Its projector-style voice coil directs audio toward listeners, making it effective both indoors and outdoors.
Q: What maintenance does it require?
A: Minimal. Occasionally check for debris on the grille and signs of bracket corrosion. Ensure weather seals remain intact.
Q: Will multiple units work on a 100 V line amplifier?
A: Yes. Use the power tappings to ensure total speaker wattage stays below ~90% of amplifier power to maintain headroom and avoid overload.
