RAY SUB IMPLEMENTATIONSystem Manual RS Series Page 43 / 767.2 Directional ModeIMPORTANTRS15 can be installed “Left” or “Right” (see section 5.2.1):- “Left” means grid is Left when looking from front- “Right” means grid is right when looking from frontWhenever possible, NEXO recommends symmetrical designs.7.2.1 Single RS15 or RS18Single RS15 and RS18 have an asymmetrical pattern in the horizontal plane (ie speakers on the side), which is tilted 30°off-axis towards speakers direction; vertical pattern (ie speakers facing up or down) is symmetrical).HORIZONTAL COVERAGE IN DIRECTIONAL MODE (100 HZ) VERTICAL COVERAGE IN DIRECTIONAL MODE (100 HZ)IMPORTANTSo that directional behaviour and acoustic load are not altered, no reflecting surface should be at lessthan 50cm (20”) from the RS15 and RS18 side walls and drivers.In case of stereo configurations, NEXO recommends that speaker side is set outwards to minimize interference region instereo designs. (ie “RS15s LEFT” should be installed Left and “RS15s RIGHT” should be installed Right).
