Too often, installers fail to appreciate the importance of maintaining the polarity of the speakers in distributed sound systems.  Consequently, the quality of both voice and music reproduction may be significantly degraded.

In a good overhead distribution pattern, the result is similar to mispolarized speakers in a multi speaker enclosure.

Installing sound systems is hard work, as anyone who has pulled wires and mounted speakers will attest.  By contrast, it is relatively easy to make sure that the same color coding is used when connecting speakers.  It does not make any difference which wire is used as the ground or the signal line as long as the same wire is consistently connected to the same color at each transformer or speaker.

At J.W Davis & Company, we carefully check out speakers to assure consistent polarity.  in addition, the line transformers are checked for polarity to be sure that the windings are polarized properly.  Finally, a visual check of the wiring is made when a sweep test is performed on the final speaker assembly.  The result is "quality you can hear."
