TOA Electronics Speaker Guide

Welcome to the TOA Speaker Guide

TOA has long been recognized as a manufacturer of high-quality, flexible, and reliable amplifiers.

For over 75 years, we have also been an innovator in the design of high-performance speaker

systems for a wide range of applications. TOA has been at the forefront in the development of

specialized loudspeaker technologies for public spaces. TOA produced some of the first pro-

fessional speaker systems that utilized dedicated electronic processing to optimize the speak-

er’s performance. TOA engineers presented the first AES papers on adaptive filter equalization

and the use of all-pass filters for flat-phase speaker tuning. Our test facilities include one of the

world’s largest anechoic chambers and state-of-the-art facilities for acoustics and reverberation

simulation. TOA was among the first to adopt the RASTI speaker intelligibility rating method

and we rigorously test our speakers using TEF 20 analyzers. TOA also assisted with the Japanese

translation of the classic text by Don and Carolyn Davis, Sound System Engineering, and has long

been a sponsor of Syn-Aud-Con sound system design seminars.

The purpose of this design guide is to provide sound contractors and systems integrators with

a convenient, easy-to-use reference to design small- and medium-sized TOA distributed speak-

er systems. The guide discusses the main parameters and trade-offs involved in designing dis-

tributed speaker systems and provides rules-of-thumb to help specify and implement them.

Disclaimer: This design guide does not cover all of the general concepts underlying sound

system design and installation, which would require several hundred pages. This guide is not

meant to replace the participation of an experienced consultant or engineer.

References: For more detailed information about sound system design principles, we recommend

support and contributions to this project. Thanks also to Don and Carolyn Davis for being guiding

lights to so many of us who work with sound and who always want the world to sound a little

(sometimes a lot) better.

Chapter 1: Getting Started: System Design

Steps

System design is essentially a process of answering the right questions in the right order. An-

swering the following questions will provide the basis of a sound design for your system. Not

included in the list is the question of project budget, which is always a guiding factor.

1. Where will the system be used?

Is it indoors or outdoors?

If indoors, is it highly reverberant?

How large is the space?

What mounting/installation options are available?

Answers to the following questions will guide the project and influence subsequent questions.

2. What will the system be used for?

Is it for music, speech, signaling tones, or a combination?

What level of fidelity, or sound quality, is required?

Is strong bass response important?

What level of speech intelligibility is required?

Defining the requirements of the system is critical to the success of the installation. Different sound

system applications and their requirements are discussed in Chapter 2: System Applications.

3. How loud must the system be?

How much noise is present in the listening environment?

Will the system be used for high-level foreground music?

Use an SPL meter to measure ambient noise levels on site during typical operating conditions.

An inexpensive SPL meter is available from Extech (http://www.extech.com). See Chapter 5:

Using Speaker Specifications for an overview of how to calculate the required sound pressure

and power levels, based on the background noise you measured or estimated.

4. What type of speakers are right for the job?

Will the job require ceiling, wall-mount, or other types of speakers?

Will subwoofers be needed to enhance the bass response?

Since the best speakers for one job may be amongst the worst for another job, proper matching

of the speaker to the installation is important. See Chapter 3: Speaker Types for a discussion of

the types of speakers most commonly used in distributed speaker systems, and the application

each is suited for.
