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 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 inch-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 toprecision tolerances for high performance, endurance and superior sonicquality.
