Optimal Mid-high Loudspeaker to Subwoofer Ratio
In this section:
meyer-blue-rule-line.png

The ideal ratio of mid-high loudspeakers to 750-LFC loudspeakers depends on the following:

  • Loudspeaker model

  • System configuration

  • Frequency content of source material

  • Headroom required for low frequencies

For LINA applications, the ratios shown in the first, second, and third figures below yield good results.

For ULTRA-X40 applications, the ratio shown in the last image below yields good results.

Flown Mixed Array (ratio 3:1)

Caution

Make sure that all cables for looped loudspeakers are wired correctly (Pin 1 to Pin 1, Pin 2 to Pin 2, etc.) to prevent the polarity from being reversed. If one or more loudspeakers in a system have reversed polarity, frequency response and coverage will be significantly degraded.

Note

  • Native mode should not be used with more advanced configurations, such as those where LINA and 750-LFC loudspeakers are not coplanar, or those requiring delay offsets to align subsystems or to create directional low-frequency control. These systems require additional processing.

  • For Native mode to work properly, the source signal must be correctly configured with the appropriate gain structure.
