SOUND PROJECTORS

Suitable for situations requiring high sound pressure and good quality for music distribution. Their construction involves a broadband speaker housed in a cabinet designed to achieve a high, well-defined sound pressure beam, as well as good frequency response.

  • They include an anchor for wall or ceiling installation. They are usually designed for outdoor installations.
  • High sensitivity, as well as acoustic performance; with a low wattage of power (lower amplification cost), high sound pressure levels are achieved (in many cases exceeding 105 dB with only 20 W).
  • Good music reproduction quality thanks to the bandwidth, >15 kHz in many models.
  • These speakers project sound over a great distance. Installed at a sufficient height (3-5 m), they facilitate the dispersion of the acoustic beam and prevent the high output sound pressure from harming nearby listeners.
  • The range depends on the height, ambient noise, and applied power. Under appropriate conditions, the most effective models can reach 20-30 m with a good sound pressure level.
  • They are installed in sports venues, parking lots, train stations, bus stations, subway stations, and more.
