CSX SERIES SUBWOOFERS - INSTALLATION
CSX Subwoofers, having omnidirectional dispersion characteristics, will normally be floor mounted in a suitable location in the
room. As the bass frequencies involved are essentially non-directional, the location will be dictated simply by convenience and
practicality. It is often only necessary to use a single subwoofer cabinet with a stereo system, as the active crossover will generate
the mono LF feed required. See “System connections” for more details regarding system connections.
Any model of CSX subwoofer may be used in conjunction with any model from the CDD Series, provided the appropriate
parameters are set up in the loudspeaker management system. However, practical combinations are likely to be as shown below:
FLYING CSX SUB-WOOFERS
CSX Series subwoofers may also be flown; ‘F’ versions are available for this purpose, pre-fitted with threaded inserts to accept
eye bolts. This option must be specified at the time of ordering, as the inserts cannot be retro-fitted.
Shouldered eye bolts are used in the inserts in the same manner as for CDD Series cabinets. Approved eye bolts are available
from Martin Audio for the subwoofers: Part No. HTKCT06 – M10 eye bolt, suitable for all CSX models.
IMPORTANT
Note that eye bolts for flying systems must be cast or machined, 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 M10 inserts in CSX 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.
Fit an eye bolt into each of the threaded inserts in the cabinet top (there are four, one in each corner).
Note that CSX Series subwoofer cabinets are not designed to mate mechanically with CDD Series cabinets and have no provision
for doing so. If flying both CDD Series cabinets and CSX Series subwoofers, they must be rigged independently of each other.
Use standard rigging techniques to raise the subwoofers to the required height. Always ensure that the rigging method and
components used are suitable for both the weight of the cabinets and the suspension points at height.
