Design the enclosure for the line array box, including:
Many designs use a "Slot-Loaded" technique where the 12" driver fires into a narrow slot before exiting the cabinet. This helps extend the mid-range response but requires precise bracing inside the box to prevent air turbulence noise. 12 inch line array box design pdf
| Frequency | SPL @ 2.83V/1m | Directivity (H×V) | |-----------|----------------|-------------------| | 80 Hz | 99 dB | 360° (omni) | | 250 Hz | 101 dB | 180° × 80° | | 500 Hz | 102 dB | 110° × 60° | | 1 kHz | 103 dB | 100° × 30° | | 2 kHz | 104 dB | 90° × 15° | | 5 kHz | 103 dB | 85° × 12° | | 10 kHz | 101 dB | 80° × 10° | Design the enclosure for the line array box,
that explains how array length, rather than driver size alone, determines directivity control at lower frequencies like 125 Hz. EAW: Eastern Acoustic Works Design Considerations Enclosure Designs - Eighteen Sound rather than driver size alone
