Using the Speakers with Powered Subwoofers:
Use the following low-pass (high filter) setting on your
powered subwoofer:
M50 - 100 Hz
M60 - 60 Hz
M80 - 50 Hz
Some powered subwoofers provide simple, passive
“high-pass” networks in series with their main speaker
output circuits. These outputs are appropriate for use
with the M50 and M60, but avoid using this type of
output with a pair of M80s; drive M80’s with an amplifi-
er’s normal speaker output.
All Cambridge SoundWorks BassCube subwoofers have
full-range, straight pass-through speaker outputs. You
can use these outputs with the M50, M60 or M80.
The Newton Series powered subwoofers have active
100Hz “high-pass” main speaker outputs for use only
with preamplifier/power amplifier systems. These outputs
can be used with any Newton Series bookshelf speaker
system. Use a 100Hz setting on the Newton Series
subwoofer’s Low-Pass control in this case.
Dolby Digital Decoder Speaker Size Settings:
If your Dolby Digital systems uses M50, M60 and M80
speakers and a powered subwoofer connected to the
SUB OUT jack, set the decoder’s speaker size settings
to SMALL. If there is a crossover frequency feature on
your Dolby Digital decoder, set it as close to 80Hz as
it allows.
Bi-Wiring
A bi-wiring hookup configuration is supported by the
M80. Bi-wiring uses one length of speaker wire to drive
the tweeter/mid-range section of the speaker and a
separate length of speaker wire to drive the woofer. Both
lengths of speaker wire are connected to the same full-
range amplifier speaker outputs.
To bi-wire an MC500, remove the jumpers and connect
the two lengths of speaker wire as shown in the diagram
We do not recommend removing the jumpers for any
other purpose.
