Yamaha Installation Series Loudspeakers provide 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.

Yamaha IS1118 Features:

  • Ideal for medium to large-scale installations.
  • Uniform phase response throughout the entire series.
  • A wide selection of dispersion characteristics for long-range, short range, and long/short range use.
  • Standard U-bracket and array-frame hardware available for maximum installation convenience and efficiency.
  • Switchable single-amp and bi-amp drive modes.
  • Certified measurement and prediction EASE data.  Including polar plots, CAD files, and DXF data.
  • Constructed of high strength premium 11-ply / 5/8" thick Finland Birch enclosures on most models.
  • Grilles have 63% transparency for better clarity of sound.
  • Speakers include a barrier-strip and NL4 Neutrik with parallel connections.
  • Horns are manufactured from fiber-reinforced plastic to minimize unwanted resonance.
  • The entire line of speakers incorporates rotatable horns, when space consideration dictates the speakers orientation.
  • High frequency drivers feature one-piece titanium diaphragms formed to precision tolerances for high performance, endurance and superior sonic quality.
