FLYING CDD SERIES CABINETS
A further installation option for Models CDD10, CDD12 ands CDD15 is to employ standard flying
techniques.
The CDD10, CDD12 and CDD15 can be flown by fitting M8 shouldered eye bolts to the cabinets
and using steel rope or chains to suspend them at the desired height from suitable fixings in
the roof. Martin Audio can supply suitably rated eye bolts for this purpose: Part No. HTKCT05,
which are suitable for all three models:
IMPORTANT
Note that eye bolts for flying systems must be cast, shouldered fittings rated for the purpose.
Forged steel eye bolts of the type typically available from DIY suppliers are NOT suitable and
should not be used under any circumstances.
The M8 inserts in CDD cabinets are recessed, and the shoulder on Martin Audio eye bolts fits
into the recess. If you use an eye bolt with a shoulder wider than the recess you will need to
space the bolt so it tightens down on the thread rather than the outer surface of the cabinet.
CDD cabinets can be flown in vertical (“portrait”) or horizontal (“landscape”) orientation.
Note that is vital that the driver is orientated to suit the deployment used. “Out of the box”
the driver is in the correct position for “portrait” use and must be rotated through 90° for
“landscape” use. Please see page 13 for details of driver rotation.
There are a total of ten M8 inserts in each cabinet, three on the top, two on the bottom, two on
each side and one on the back (terms with reference to the cabinet in portrait orientation). Note
that the inserts on the top, bottom and sides are recessed into the cabinet; spacers or washers
must be used in these positions so that the eye bolts can be tightened sufficiently.
