Yamaha Installation Series Loudspeakers

The Installation Series provides a wide range of models with seamlessly integrated hardware to meet the expectations of contractors and end-users for audio quality, ease of installation, and system design. All models feature a phase differential of less than 90 at 2 kHz . This minimizes the reduction of sound level and unwanted coloration in the "overlapped" area when combining/arraying speakers. The overall effect on frequency response is held to a minimum, ensuring a consistent family sound of speakers.

  • Ideal for medium to large-scale installations.
  • Uniform phase response throughout the entire series.
  • A wide selection of dispersion characteristics forlong-range, short range, and long/short range use.
