Farasout Negar, an audio integration company based in Tehran, recently completed the design and installation of a PA system for calling Muslims to prayer at the Imam Mousa Kazim Holy Shrine in Kazmein, Iraq.

To achieve 360-degree coverage and very high SPLs, Farasout Negar designed a system based on sixteen Community RSH-462 exponential FocusedArray™ horn systems. Each voice-range RSH-462 utilizes four Community M200 ferrofluid-cooled compression drivers mounted to a hand laminated, reinforced composite fiberglass horn-array with a 60 degree horizontal and 20 degree vertical coverage pattern.

With a sensitivity of 117dB for 1W at 1 metre and a 750W program power handling capacity, the Community RSH-462 was the best choice to provide the considerable SPL required.

Coverage was achieved by mounting four RSH-462 in each of the Shrine’s four minarets, at a height of 33 metres from the ground. Although the loudspeakers are mounted in the minarets, they are open to the full environmental conditions of Kazmein, so their all-weather capability was another important consideration for Farasout Negar. The one-piece, non-metallic diaphragm of the RSH-462 faces forward, isolating the voice coil and magnetic structure of each driver from the environment, providing the needed resistance to the effects of humidity and dust.

From the compact R.25 and R.5 to the powerful R6-51, there is a Community R-Series loudpspeaker for every installation. Highly weather resistant for outdoor applications, but very appropriate for indoor use as well, the R-Series offers exceptional voice clarity and sound projection capability. R-Series systems are found in the world’s premier amusement parks, sports arenas, cruise ships, and race tracks as well as countless university and high school sports fields. All R-Series loudspeaker enclosures are warranted for structural integrity for 15 years.
