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-S3” – 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 Viewer”. An introduction to Y-S3and 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 suitable array frames, but also “acoustically 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!

IF2112 specifications

The Yamaha IF2112 is a prominent addition to Yamaha's line of professional passive loudspeakers, designed to deliver exceptional sound quality and reliable performance in various sound reinforcement applications. This model stands out for its versatility, making it suitable for everything from live performances to installations in commercial spaces.

One of the key features of the Yamaha IF2112 is its dual 12-inch LF (low-frequency) drivers, which provide a robust bass response that is both punchy and accurate. This is complemented by a unique horn-loaded design that incorporates a 2-inch titanium diaphragm compression driver. The result is a consistent and even dispersion of sound, ensuring that audiences enjoy quality audio regardless of their location within the venue.

The IF2112 is constructed with a sturdy, durable polyurea finish that not only enhances aesthetics but also protects against wear and tear. The cabinet design includes a rear input panel with connector options for flexibility in various setups. Additionally, the speaker is equipped with integrated rigging points that facilitate easy and secure mounting in both horizontal and vertical orientations.

In terms of performance, the IF2112 boasts a frequency response range from 55 Hz to 20 kHz, allowing it to reproduce a wide spectrum of audio, from deep bass to clear highs. With a power handling capacity of 500 watts RMS and a peak power handling of 2000 watts, the IF2112 is capable of producing high sound pressure levels, making it suitable for larger venues.

Yamaha's Advanced Wave Guide technology enhances the IF2112's performance by ensuring sound coverage is uniform across the audience area. This is particularly beneficial for live sound applications, where even sound distribution is critical to the overall experience.

Furthermore, the IF2112 features a lightweight design, making it easier to transport and set up, a significant advantage for mobile sound engineers and rental companies. Its compatibility with various Yamaha amplifiers also allows users to maximize the speaker's capabilities, ensuring optimal quality and performance.

Overall, the Yamaha IF2112 is a powerful and versatile loudspeaker that combines advanced technologies with robust design, making it an excellent choice for both professionals and enthusiasts in need of high-quality sound reinforcement.
