Frequently Asked Questions: Expert Answers for Procurement Professionals

Who invented the line array concept?

The foundational principles of line array acoustics were first explored by Harry F. Olson in the 1930s. His research demonstrated how vertically aligned speakers could create directional sound beams with controlled dispersion—now a core feature of modern concert systems.

Why are line array speakers so expensive?

Professional line arrays command premium prices due to complex engineering, aerospace-grade aluminum frames, precision-machined waveguides, and rigorous environmental testing. Unlike consumer speakers, they must endure constant transport, extreme temperatures, and daily high-power operation.

What is an example of line array physics in nature?

Imagine dropping a long plank into water—the resulting wavefront starts as a cylindrical spread close to the source (near-field) before radiating outward spherically (far-field). This mimics how line arrays project sound efficiently over long distances with minimal drop-off.

How can I verify a supplier’s reliability before committing?

Conduct virtual factory tours, request third-party electroacoustic test reports (e.g., Klippel or LinearX data), and validate references from clients in similar markets. Cross-check business licenses and past shipment records via trade verification platforms.

What is the typical production timeline?

After design approval, standard production takes 30–45 days. Expedited orders can be completed in 21 days with rush fees. Add 10–15 days for prototype development and acoustic validation.
