Dual 10-inch 3-Way LineArray Loudspeaker

The L-1 line array speaker system is a large-scale, 3-way, dual-driver loudspeaker.

It delivers a frequency range of 60Hz–20kHz.

The system is composed of a 3-inch (75mm voice coil, 36mm throat) neodymium compression high-frequency driver,

one 8-inch neodymium midrange driver, and two 10-inch neodymium low-frequency drivers,

forming a sound reinforcement system with an exceptionally high dynamic range.

The low-frequency section uses two 10-inch paper-cone woofers, arranged in a left-right symmetrical configuration in series.

The midrange driver is equipped with a phase plug and a constant-directivity horn, effectively improving coverage control and

enhancing overall sensitivity.

The high-frequency section adopts a 75mm neodymium titanium diaphragm compression driver,

coupled with a planar wave converter and a 90° exponential constant-directivity horn, generating a uniform wavefront.

With a sensitivity as high as 100dB, the L-1 can deliver peak sound pressure levels up to 135dB.
