Pure Resonance Audio S8.1 IP65 8 Inch 70V Surface Mount Speaker

If you need a commercial-grade 70V surface mount speaker that looks clean and modern but still holds up outdoors, the Pure Resonance Audio S8.1 is a strong choice. It is built for restaurants, patios, retail spaces, gyms, schools, houses of worship, hospitality venues, and anywhere you want clear background music and intelligible paging without babying the gear.

The enclosure is UV-resistant ABS with a metal grille, and it is IP65 rated when properly installed, meaning it is designed to handle dust plus direct contact with moisture and rain in real-world installations. The sealed rear cover design also helps protect the connection point and transformer area, which is where outdoor installs usually fail first.

Sound-wise, the S8.1 is a true 2-way design with an 8 inch graphite woofer and a 1.1 inch silk soft dome tweeter, tuned for clean vocal clarity and smooth music playback. The built-in OBE (Optimal Bass Enhancement) radiator technology is the secret sauce here, it helps the speaker sound fuller on patios and open areas where bass usually disappears. You get a solid 60Hz to 20kHz frequency range, 90 dB sensitivity, and up to 102 dB max SPL, so it stays clear even when the space gets noisy.

Installation is straightforward for commercial work. You get a waterproof surface mount bracket that can mount vertically or horizontally, and it supports precise aiming with panning adjustment. Wiring is via a 4-pin Euroblock screw terminal, and the speaker includes a built-in 70V and 100V transformer with practical tap options:

70V taps: 3.12W, 6.25W, 12W, 25W

100V taps: 6.25W, 12.5W, 25W, 50W

Plus an 8 ohm bypass for traditional low impedance systems

In the box you get the S8.1 speaker and the surface mount bracket, so you can go from unboxing to installation without chasing extra hardware. Bear Security Shop sells and ships to US customers only, and this is the kind of speaker that reduces callbacks because it is built for the environment it is installed in.

Benefits
You get a cleaner looking surface mount install that still performs like a real commercial loudspeaker. The IP65 outdoor durability means fewer replacements over time, the transformer taps make system design easy on 70V and 100V runs, and the 8 ohm bypass keeps it flexible for smaller amps. Most importantly, the OBE bass enhancement helps music sound less thin outdoors, while the silk dome tweeter keeps paging and vocals easy to understand.
