Sound Barrier STRATUS15H — 15-Inch Passive Coaxial Two-Way High SPL Weather-Resistant Loudspeaker
STRATUS15H Overview
The Sound Barrier STRATUS15H is a compact, full-range, wide-dispersion two-way loudspeaker system designed for installations demanding very high output and extended throw distances. Built to IP56 weather-resistant standards, it is purpose-built for permanent outdoor deployment in environments where exposure to the elements is a constant operational factor. The high-frequency section pairs a constant directivity horn with a 1.4-inch precision compression driver featuring a 3-inch diaphragm assembly, delivering smooth, controlled dispersion across the coverage pattern. The low-frequency section is driven by a 15-inch woofer with a 3-inch voice coil, providing the low-end foundation required for high-SPL applications. This loudspeaker is well suited for system integrators and audio engineers specifying permanent installations at sports facilities, stadiums, water parks, and large outdoor venues.
The cabinet ships with an integrated stainless steel U-Bracket, simplifying rigging and positioning in fixed-installation environments where corrosion resistance and structural reliability are essential.
Key Features
- IP56 Weather Resistance — Rated for protection against dust ingress and powerful water jets, making it suitable for permanent outdoor installations in harsh environments
- 15-Inch Low-Frequency Woofer — Features a 3-inch voice coil for high power handling and the low-end output required in high SPL, longer throw applications
- 1.4-Inch Compression Driver — Precision HF driver with a 3-inch diaphragm assembly for detailed, extended high-frequency reproduction
- Constant Directivity Horn Loading — Provides smooth, wide, and consistent dispersion across the coverage area, reducing hot spots and maintaining intelligibility at distance
- Full-Range Two-Way Coaxial Design — Compact cabinet form factor delivers broadband coverage without requiring supplemental HF enclosures in many applications
