PSW-2 and MSL-4
The PSW-2 is compatible with the MSL-4, CQ, and MTS-4.
However, since the LF (low frequency) response for each
speaker overlaps with the PSW-2, the system frequency
response exhibits a rise in the range 65– 120 Hz (MSL-4),
40–120 Hz (CQ), and 30–120 Hz (MTS-4). 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.

LD-1A with PSW-2 and MSL-4
Activating the Lo Cut filter on the LD-1A for the CH 1
Mid-Hi output also eliminates the LF rise caused by the
overlap between the MSL-4 and PSW-2. Although a
typical MSL-4 : PSW-2 ratio is 2:1, CH 1’s Sub and Mid-
Hi level controls allow the ratio to vary while maintain-
ing control of the spectral balance of the system.

Including subwoofers in a flown cluster provides a smooth
frequency image because the low and mid-hi frequencies
are produced from speakers located close together. The
identical dimensions of the PSW-2 and MSL-4 allow them
to be easily flown together.
The CH 1 Mid-Hi output drives the MSL-4 with the Lo
Cut filter in. The CH 1 Sub and DS-2 outputs drive the
650-Ps and PSW-2s with the DS-2 & Sub Crossover
switch out, which sends a full-range signal with inde-
pendent level control to each speaker.

Set the MSL-4 and PSW-2 to the same polarity. The polarity
for the 650-P depends on the distance of the measurement
position relative to the subwoofers and the flown cluster.
PSW-2 and USW-1
Although it is preferable to employ the PSW-2 in a
completely self-powered system, the PSW-2 can be used
with the USW-1 externally amplified subwoofer if:
• the B-2EX CEU is set to the maximum output
level;
• the USW-1’s amplifier is set to 26 dB gain;
• the PSW-2 is set to the opposite polarity to the
USW-1 amplifier.

POLARITY NOTE:
It is advisable to check the polarity of
adjacent PSW-2 and USW-1 cabinets by following the
instructions in the
Verifying Driver Polarity
section on
page 10.
