Horizontal dispersion is typically designed for 90∘90 raised to the composed with power 110∘110 raised to the composed with power
The waveguide must convert the spherical wave from the compression driver exit into an exact planar (flat) wavefront.
12-inch drivers offer significant punch and low-mid reproduction, reducing the reliance on massive subwoofer banks.
High-Pass Filter (HPF): 60 Hz, Butterworth 24 dB/octave (or Linkwitz-Riley 24 dB/octave).
The industry standard. Use 15mm (5/8 inch) or 18mm (3/4 inch) 11-ply or 13-ply void-free Baltic birch. It offers the best strength-to-weight ratio and acoustic damping.
A 12-inch line array box is usually designed for medium to large-scale events, often featuring a 12-inch woofer (or dual 12s) for mid-bass and a high-frequency driver with a specialized wave-guide. A. The "Line Source" Concept
Apply a low-mid shelving cut (often between -3 dB to -6 dB depending on array length) to restore tonal balance.
To wrap things up, here are some final bits of wisdom to guide your project:
0.25 – 0.35 (optimized for vented or horn-loaded enclosures) Xmax (Linear Excursion): ≥is greater than or equal to 5mm – 8mm Sensitivity: ≥is greater than or equal to 97 dB @ 1W/1m Compression Driver Selection (High Frequency)
Assume single 12" driver with parameters: Vas = 80 L, Fs = 40 Hz, Qts = 0.35.
Line array systems are the backbone of modern live sound reinforcement, offering unmatched control over vertical coverage, high SPL (Sound Pressure Level) capabilities, and consistent sound quality over long distances. Designing a 12-inch line array box requires a delicate balance of acoustics, physics, and structural engineering.
Finding accurate CAD or PDF plans is essential for professional results. Several resources offer detailed designs:
This guide breaks down the essential design principles, component selection criteria, and rigging considerations needed to build a professional-grade 12-inch line array system. 1. Acoustic Concepts of Line Array Systems
Q: What is the ideal frequency response for a 12 inch line array box? A: The ideal frequency response for a 12 inch line array box is flat across the entire audio spectrum, with a range of 50 Hz to 20 kHz.
Bass-reflex (ported) to maximize low-end punch. Mid-Frequency (MF) Section (Optional Tri-Amp Setup) Driver: Dual 5-inch or 6.5-inch drivers. Frequency Range: 400 Hz to 1.2 kHz. High-Frequency (HF) Section
Connect the side rigging plates internally using steel reinforcing bars. The load of the entire hanging array must pass through steel-to-steel connections, never solely through the wooden panels. 7. Enclosure Finishing and Testing
