5 Flying CDR 210 C
Subwoofers
5.1 Components
The following components are required to fly
CDR 210 C subwoofers:
• a standard rigging frame.
• the pick points on the side panels of COHEDRA
®
Compact CDR 210 C subwoofers
• the CDR 210 C Rigging Set consisting of four
connector components and eight pins
5.2 As an Independent Bass Array
on a Second Rigging Frame
The standard rigging frame is certified to fly up to
six CDR 210 Cs in stacked array. Read and heed also
the safety regulations in chapter C of the manual.
Rigging
Set the standard rigging frame on the CDR 210 C
subwoofer with the rubber feet facing down. Remove
the four pins on the rigging frame. Attach the four
(optional) connector components between the rigging
frame and the CDR 210 C using the pins. Attach the
shackles for the motor to the rigging frame. Attach
the motor to the shackle and lift the subwoofer.
Now you can rig additional CDR 210 C bins below
this subwoofer. To do this, you need four connector
components and eight pins for each subwoofer.
(=1Set)
5.3 In Combination with
CDR 108 C Mid/High
Configuring subwoofers and mid/high units together
in a single array can be a viable option, depending
on application. Subwoofers must be rigged on top
of the flown array for this application.
Mind the rigging frame’s maximum permissible load.
Before you begin, add up the individual components’
weights to determine total system weight. Refer to
tables 1 and 2 for weight specifications.
6 Configuring CDR 210 C
Subwoofers in Clusters
CDR 210 C enclosures have been optimized for
setting up clusters comprising four subwoofers.
When configuring a cluster, set up the bins so that
the bass reflex apertures point toward each other.
This ensures the various subwoofers’ low-frequency
signals couple for maximum sonic effect. To this end,
set one row of speakers bottom side up (see Fig. 22).
The housings are equipped with feet on the bottom
and top panels. Refer to the labels on the connector
panel for details.
