Summary

none of the existing approaches have the inventors taken the same design approaches as

Bose in the case of the MA12™ array . The goals in creating the MA12 were exceptionally

high acoustic output from an ultra-thin baffle area, a wedge-shaped radiation pattern and

gentle fall off of sound characteristic of cylindrical waves, and wide horizontal dispersion in

a lightweight, modular, architecturally unobtrusive, and affordable package. It is our belief

that we have succeeded in this regard. However, we welcome the fact that designers and

customers alike will be able to judge for themselves the degree to which they agree with our

claims. We recognize that the success of the design depends on their judgement, not ours.

DESIGNING WITH THE MA12

this section, some of the basic rules for applying the MA12 are presented. These rules are

intuitive given the wedge-shaped radiation pattern of this speaker. For a listener to be

covered with sound from a source with a wedge-shaped radiation pattern, his or her ears must

be contained between two imaginary 160° wedge-shaped surfaces, one extending from the

top of the speaker, and the other extending from the bottom.

To cover a large flat audience area with sound, a single MA12 module is placed as shown

in Figure 12. It is located so that the bottom of the array is about at the height of the chest of

a person seated in the first row. Other modules may be added if necessary until the top of the

array covers the head of a listener in the last row. (In the figure, only one module is used.)
