Driver Rotation
DDX loudspeakers are shipped from the factory ready for deployment in vertical – or portrait – orientation. If the loudspeakers are installed
horizontally, the coaxial driver must be rotated through 90° to maintain the correct dispersion patterns.
DDX coaxial drivers are not symmetrical. For correct dispersion characteristics the driver should always be orientated as shown, with the
narrowest part of the HF waveguide towards the bottom of the enclosure.
To rotate the driver, proceed as follows once the grille has been removed:
Using a hex key:
DDX8 4 mm
DDX10 4 mm
DDX12 5 mm
DDX15 5 mm
Lift the driver assembly out and rotate it through 90°.Remove the screws securing the driver to the baffle board.
There will be between four and eight screws depending on the
loudspeaker model.
Replace the bolts and the grille.
Note: If the loudspeaker in portrait mode is installed upside down the driver must be rotated through 180° to ensure the correct dispersion
characteristics.
