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.
