8 Achieving center channel bass
The CCR is called a "small" speaker due to the limited mid-bass response. The
least complicated way to achieve true Maggie sound is with one or two DWM
Bass Panels or the CC Speaker Stand. (The more complex method of using the
processor's bass management system is explained below.)
The DWM Bass Panel is 2 "voice grids" and crossover within one panel. Wire
the amplifier inputs in parallel (plus to plus and minus to minus). Wire the
CCR to the "high" output of one of the DWMs (Do not use both "high"
outputs). Note-- The resultant impedance will be a nominal 3 ohms. This
requires the use of a high-current amplifier.
The DWM Bass Panel should be placed close to equi-distance to the CCR. It is
not essential that it be the exact distance, but as close as is practical.
To prevent over-driving the Bass Panel with movies, it may be advantageous to
cross over the center channel bass at approximately 40-60 Hz for home theater.
If two Bass Panels are used, the unused sections of both Bass Panels may be
used in the same manner as described above.
Getting the midbass/bass for the CCR adjusted correctly is the single most
important part of getting the most out of your CCR's performance.
As an owner of a higher quality system, most likely you own a processor with
adjustable crossover points for "small" speakers. Set your processor for "small"
center channel speaker. Set the center channel crossover point at 200-250 Hz
for optimal frequency response or as low as 150 Hz if your processor does not
provide up to 200-250 Hz. You will be instructed to turn the subwoofer "off "
on your processor. After reading all the instructions below, play the Magnepan
Wide-Band Center Channel Pink Noise DVD which is included with your
CCR. If the correct procedures are followed, your CCR will give the illusion of
a large Magneplanar in the center. If your processor does not have flexible
crossover settings, DWM Bass panel or the CC Speaker Stand may be the best
option to achieve good center channel bass/midbass.
