RL18S Standard Cardioid Configurations
The RL18S features push-button cardioid functionality, allowing two or more RL18S subwoofers to
be used together in a cardioid configuration. Cardioid functionality is possible in a number of
different physical configurations, demonstrated below. These configurations can be scaled by
adding equal numbers of front, and back facing subwoofers to achieve cardioid patterns with
additional SPL output capabilities.
Two RL18S Stacked Horizontal
Two RL18S subwoofers can be stacked, one on top of
another to achieve a cardioid coverage pattern. The
subwoofer facing towards the audience should be set to
‘Cardioid Front’ with the other subwoofer set to ‘Cardioid
Back’.
Two RL18S Side-by-Side Horizontal
Two RL18S can be placed side-by-side to achieve
cardioid coverage pattern. The subwoofer facing
towards the audience should be set to ‘Cardioid
Front’ with the other subwoofer set to ‘Cardioid
Back’.
Two RL18S Side-by-Side Vertical
Two RL18S can be placed side-by-side to achieve
cardioid coverage pattern. The subwoofer facing
towards the audience should be set to ‘Cardioid Front’
with the other subwoofer set to ‘Cardioid Back’.
