Speaker Placement and Polarity
The cabinets in the following example configurations
are in a close-proximity coplanar orientation, unless
otherwise stated. Placing the mid-hi speaker more
than 5 feet from the subwoofer may require setting the
speakers to opposite polarities to compensate for the
propagation delay between them.

In a coplanar orientation, externally amplified Meyer
subwoofers require the opposite polarity setting to
all Meyer self-powered speakers.

and CP-10 Parametric Equalizer to
• assist the process of configuring and placing
speakers in a system;
• measure propagation delays to set the correct
polarity between speakers;
• measure and equalize variations in frequency
response caused by the acoustical environment
and the placement and interaction of speakers.

The LD-1A Line Driver
We recommend using the Meyer LD-1A Line Driver
to integrate different types of Meyer self-powered
speakers into a full-range system. The LD-1A maintains
signal integrity for long cable paths, has two channels
equipped to control a main system, and six auxiliary
channels for down-fill, front-fill, and delay systems. The
LD-1A provides these useful functions:

groups of 3 to 5 horizontally arrayed MSL-4s.

• The DS-2 & Sub Crossover switch activates a

80 Hz to the Sub output, and above 80 Hz to the
DS-2 output. With the switch out, a full-range
signal is sent to the DS-2 and Sub outputs.

• The Mid-Hi, DS-2, and Sub outputs each have
their own gain control and mute switch.

CQ and 650-P
The CQ is particularly well matched with the 650-P and
also performs efficiently with the PSW-2 and PSW-4.
Due to the overlap in frequency response between
the CQ and the subwoofer, the system frequency
response contains a rise in the range 40–120 Hz. It is
important to emphasize that the speakers are in phase
in this region. The rise can be corrected using the Meyer
CP-10 Parametric Equalizer, if desired.

Although it is preferable to use the CQ in a completely
self-powered system, excellent results can still be
achieved using the 650-R2, USW-1, and MSW-2.
