| Boxes in Array | LF -3 dB | HF Throw (100m) | Vertical Beamwidth | |----------------|-----------|----------------|--------------------| | 1 | 90 Hz | 75 m | 50° (no control) | | 4 | 65 Hz | 180 m | 12° | | 8 | 55 Hz | 280 m | 6° |

All structural joints should be routed with dado or rabbet joints, glued with waterproof polyurethane wood glue (e.g., Titebond III), and secured with heavy-duty countersunk screws. 5. Waveguide Integration & Splay Angle Optimization

A standard 12-inch line array box uses a trapezoidal geometry. This shape allows the cabinets to be splayed at varying angles relative to each other to target specific audience areas without creating physical gaps at the front of the array. Visual Architecture & Dimension Constraints

: Brochures covering the X-Line Xvls series describe configurations using two low-frequency drivers of 12-inch to 15-inch diameter. 12 inch line array box design pdf

The heart of the box is the high-frequency waveguide. For a diy or custom build, sourcing a proven OEM waveguide (such as those from B&C, 18 Sound, or Beyma) is highly recommended over attempting to mold a custom isophasor.

When designing a 12-inch line array box, several factors must be considered, including:

Higher sensitivity allows for louder output with less power. 50 Hz – 20 kHz Covers the full musical spectrum for balanced sound0;502;.

A line array works by arranging multiple sound sources (woofers and waveguides) in a vertical line. This configuration produces a cylindrical wavefront, which reduces sound level decrease over distance compared to traditional point-source speakers.

Information on how to safely connect the cabinets together to create a line. Summary Checklist for Building Material: 18mm Baltic Birch Plywood. This shape allows the cabinets to be splayed

The center-to-center distance between adjacent acoustic sources must be less than half the wavelength of the highest frequency they emit.

Use large-area slot ports alongside the woofer to prevent port turbulence (chuffing) at high volumes. Flaring the internal edges of the slot ports helps smooth out airflow. Trapezoidal Geometry
