Bose Panaray MA12 Teknik Temel ve Tartışma
Thus a line-shaped source has the potential to satisfy all of the major customer
requirements in ways that often overcome some of the weaknesses of the hang-and-tilt
approach. As such, a well-executed line-shaped source would not be simply an incremental
improvement to the well-worn products and techniques used in hang-and-tilt designs. It
would represent an important new tool that would significantly increase the options designers
have in many venues. The potential would exist to satisfy the basic customer requirements
and to do so in many cases at substantially less cost. Such a source would therefore represent
something more significant than an incremental advancement. The remainder of this
document is devoted to providing evidence that such an advancement has been made.
BOSE MA12™ MODULAR ARRAY
T
Bose MA12 array is a one-meter tall speaker module consisting of twelve closely-spaced
HE
high-output 2.2" (6 cm) drivers operating over the frequency range from 120 Hz to 16 kHz. A
one-meter module was chosen because it is tall enough to produce the desired wedge-shaped
radiation pattern, short enough to be easily handled, and modular so that longer line sources
can easily be constructed.
In the MA12, the drivers chosen exhibit pistonic behavior up to higher frequencies than
what could be achieved with larger drivers of similar quality, a desirable feature when the
goal is to create the wedge-shaped pattern over a very wide range of frequencies.
The small driver diameter was also chosen so that the source would have very wide
horizontal dispersion. The MA12 has 160° of coverage up to very high frequencies. This is
important because when the audience is close – a definite possibility because the gentle
change in level with distance means it is not too loud close to the speaker – it tends also to be
distributed over a wide angle.
The ultra-slim profile of the MA12 , also a consequence of the driver chosen, means that the
speaker blends into almost any environment. A single array module has a surprising height-
to-width aspect ratio of 12:1. If two modules are used, this increases to 24:1. Taken together
with the fact that the speaker is available in black and white and can also be easily painted,
we believe it is fair to say that it will virtually disappear into most rooms.
