Description

The Monument Series BlockRock-ST is an on-ground sealed omnidirectional outdoor speaker built to integrate into landscape and architectural environments. It delivers wide dispersion from a two-way coaxial driver configuration and is offered in a slate finish that blends with stonework and hardscape. The enclosure is constructed from a non-polluting stone and resin compound engineered for long-term outdoor exposure.

Key features include a 6.5in coaxial woofer and a 0.75in dome tweeter that provide clear midrange and extended high frequency response. The speaker is rated to 70 W RMS continuous power and 140 W program power, enabling reliable playback levels for ambient and foreground applications. An optional 64 W transformer is available for use in 70 volt distributed audio systems.

Performance specifications show a frequency range of 65 Hz – 20 kHz (±10 dB) and 76 Hz – 19.5 kHz (±3 dB), with sensitivity rated at 89 dB at 1 W/1 m and 92 dB at 2.83 V/1 m. Nominal impedance is 8 ohms and the maximum SPL at 1 m is 107.4 dB, providing measurable output for outdoor coverage. The speaker is CE and RoHS certified and built to withstand rain, frost, snow, and ice.

Connectivity is handled via pigtail wire leads for direct wiring into low impedance or transformer-equipped systems. The tap selector is implemented through the same wire leads for simple wiring on site. Included wire nuts simplify initial connections and optional accessories include a TF-WS64-70 transformer and a security bracket (RSB1) for mounting security.

The BlockRock-ST is suitable for landscape audio, outdoor dining areas, resort and poolside environments, and architectural accent sound. It is designed to provide even omnidirectional coverage for ambient music or distributed sound systems while maintaining visual discretion. The stone-reinforced enclosure reduces maintenance and preserves appearance in exposed conditions.

Installation is straightforward for trained AV or landscape professionals and the sealed enclosure eliminates the need for weatherproofing modifications. The durable material composition and rated certifications support long service life in temperate to cold climates. Overall, the BlockRock-ST offers a balanced combination of acoustic performance and rugged outdoor resilience.
