Vertical And Horizontal Deployment - Martin Audio CDD Series User Manual

CDD

VERTICAL AND HORIZONTAL DEPLOYMENT

CDD speakers are shipped from the factory ready for deployment in vertical – or "portrait" – orientation. If the installation favours
horizontal orientation, the coaxial driver must be rotated through 90° to maintain the correct dispersion patterns. Inadequate
coverage and generally sub-optimal performance will result from mounting a CDD speaker with the driver incorrectly orientated.
It can be seen from the above views that the CDD's coaxial driver is not symmetrical. For correct performance, the driver should
always be orientated as shown, with the "butterfly wings" of the HF driver assembly biased towards the bottom of the enclosure.
A graphic can be found on the rear of the cabinet to confirm the correct orientation:
To rotate the driver, proceed as follows:
1. Place the enclosure face-up on a bench, table or other suitable flat surface.
2. Follow the instructions for grille removal in the section below "Grille removal and replacement".
3. Using a No. 2 Pozi screwdriver (CDD5) or a hex key (CDD6: 2.5 mm AF; CDD8/10:
1. 4 mm AF; CDD12/15: 5 mm AF), remove the screws securing the driver to the baffle board. There will be between four
and eight screws depending on the particular CDD model.
4. Gently lift the driver assembly out, rotate it through 90° and replace it.
5. Refit the screws removed in Step 3.
6. Follow the instructions for grille replacement in the section below "Grille removal and replacement".
7. Follow the instructions in the section below "Badge rotation".
Note that if, for any reason, it is necessary to mount the CDD speaker in portrait mode "upside-down", the driver must be rotated
through 180° using the same procedure described above.
