The lightest and loudest mass notification speakers on the market, with outstanding speech clarity with an average Speech Transmission Index* (STI) rating of 0.85 out of 1.0. Due to this ability to transmit human voice messages over long distance at great clarity, these speakers are the solution for PA professionals to design and build a project with fewer number of speakers versus traditional speakers for a given site, thereby saving costs in cabling, installation and maintenance.

*The closer the STI value approaches zero, the more information is lost. STI of 1 means perfectly intelligible speech.
