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.
