12 Inch Line Array Box Design Pdf Fixed -
Complete Design for a 12" 2-Way Passive Line Array Element
1. System Overview
- Type: Passive 2-way line array module
- Woofer: 1 × 12" (300 mm) neodymium, 3" voice coil
- Driver: 2 × 1.4" exit compression driver (or 1 × 2") on a proprietary waveguide
- Frequency response: 60 Hz – 18 kHz (±3 dB)
- Sensitivity: 102 dB (1W/1m)
- Impedance: 8 ohms (woofer) / 16 ohms (HF) → passive crossover to 8 ohms total
- Power handling: 500 W AES (LF) + 100 W AES (HF)
- Dispersion (per box): 90° H × 10° V (vertical splay angle = 10° for constant curvature arrays)
- Inter-element angle: 0°–10° adjustable (via rigging)
- Enclosure shape: Trapezoid (6°–12° side walls), Baltic birch plywood
If you need a ready-to-print technical drawing (DWG/PDF) or a simulation file (EASE, GLL), let me know and I can provide the structure for those as well.
The Waveguide: The most critical part of the design. It transforms the circular output of a compression driver into a flat, rectangular ribbon of sound. Enclosure Design Specifications 12 inch line array box design pdf
- Curved single driver per module vs multi‑driver cabinet. Example: two 12" in a single element for lower cutoff and higher SPL.
- Manufacturer's documentation: Many professional loudspeaker manufacturers, such as JBL, QSC, or Linea, provide detailed design and installation guides in PDF format.
- Design guides: Online forums and websites, such as AVS Forum or Sound on Sound, often provide design guides and tutorials on building line array systems.
- Research papers: Academic research papers on loudspeaker design and acoustics can provide in-depth information on the theoretical aspects of line array design.
