More and more, church systems must meet a diverse set of
needs. You can spend a good deal of time, money and effort
in developing your system, but if the loudspeakers are not
right for the job, you're less likely to be pleased with the
system's overall performance.
There are a number of quality professional loudspeakers available,
but the key is matching your specific needs with the loudspeaker
that will best meet those needs. Articulate speech and musical
fidelity are two criteria vitally important to your services
and other functions.
The following suggestions are intended to help point you in
the right direction. It's also highly recommended that you
work with qualified sound system consultants and contractors
to insure optimum results.
Decide on Standards of Comparison. Next to great sound
(which is a subjective decision), determine what is most important
to you. Size, price, reliability? Before you begin listening
evaluations, narrow the field to a few systems. This list
of candidates should be as closely equivalent to each other
as possible with regard to the criteria that you determine
as most important in your purchasing decision.
Use Familiar Material. If possible, try to arrange
for a live comparison of your leading loudspeaker candidates
in the space where theyll be used, or at least a space
with similar characteristics. Clergy and lay celebrants should
speak through the system when listening, determine
which loudspeaker sounds closest to the natural vocal signature
of the people talking. With music, choose selections youre
familiar with, and ones that mirror the types of music featured
at your services.
Use Your Ears, Not Your Eyes. As you look at your potential
loudspeaker choices, you'll soon discover that no two manufacturers
use exactly the same measurement standards when creating specifications
for their loudspeakers. By all means, read the product literature;
it can sometimes offer valuable information. But remember
- listening to comparable systems is the only test of actual
performance.
Use Your Feet as Well as Your Ears. You'll start out
standing right in front of the loudspeaker, but most of the
audience will not be sitting there they spread out
far and wide. You need to hear how the sound changes as you
move to the side, above and below, close up and far away.
Ask your contractor how much of the space the system is intended
to cover, then walk that space as you listen.
Listen to Your Collaborators. Most people can easily
recognize a "good" loudspeaker system. Natural,
undistorted sound makes a distinctive impression on which
you and the other members of your building committee can agree.
Focus on the Voice. The spoken word should be reproduced
as naturally as possible to accurately convey full content
and emotion. To achieve this, consider loudspeakers that employ
a true three-way design. Three-way systems offer a separate
mid-range driver to handle almost the entire vocal range.
The subtle voice characteristics tend to emerge clearly, and
distortion is dramatically reduced.
Choose carefully and don't be afraid to voice your opinion
when selecting loudspeakers. If you don't like what you're
hearing during the demonstration process, resist the temptation
to settle for second-best, and keep trying. Eventually you,
your peers and your contractor will agree on the right solution
for your house of worship's specialized needs.
