LOUDSPEAKER CONFIGURATIONS
3.1
Standard configuration
In standard configuration, a subwoofer system operates with an omni-directional directivity pattern.
It corresponds to the use of subwoofers as single elements or as standard subwoofer arrays.
The SB15m subwoofers are driven by the LA8 or the LA4 amplified controller with one factory preset offering a 100 Hz
upper frequency limit.

acoustic centers must be 1.7 m.
