Application Guide for
Yamaha Installation Series Speakers
Introduction
This application guide shows system design examples of the Yamaha Installation Series Speakers.
Here, typical speaker layouts comprising single loudspeakers and speaker clusters suited to the size,
geometry and application of the room are shown.
We hope that by applying the examples shown in this guide, this application guide may assist your
speaker system design
The IF2112 (12” LF) and IF2115 (15” LF) models featured in this first edition are higher power models.
Various examples using 12” & 15” LF medium power models and three way high power models will be
provided in the forthcoming second edition.
Important parameters such as coverage area, SPL and frequency response of speaker arrays can be
worked out easily by using “Y-S
3
” – Yamaha Speaker System Simulator software.
Common Loudspeaker Format (CLF) data such as frequency response, balloon data, polar pattern,
directivity, and impedance response of each speaker model is provided in the free downloadable “CLF
V iewer”. An introduction to Y -S
3
and the CLF Viewer follows at the end of this guide.
Also U-brackets, Array frame and Pin out are introduced. Yamaha prepares many kind of bracket to fit
various uses.
Yamaha Installation Series Speakers pursue the goal of being "truly arrayable". Yamaha considers this to
be not only physically arrayable by providing suit able array frames, but also “acousticall y arrayable” by
ensuring maximum phase coherence and minimum destructive interference.
In order to realize the goal of being “Acoustically Arrayable”, Yamaha unified the phase curve for the
whole Installation series, thereby minimizing SPL cancellations caused by phase difference between
speakers in a speaker array.
A further benefit of this unified phase response is the sonic consistency when different models are used
in the same room, resulting in less ‘muddiness’.
We hope that Yamaha Installation Series Speakers help you to improve your projects’ sonic
environments!
