Product Features:

LA-312 is composed of three 1.75" titanium film high-frequency compression driver units, two 6.5" mid-high frequency driver units and a 12" low-frequency driver unit. It has huge dynamic margin and is an active three-way line array speaker. .

The tweeter driver unit uses multi-horn technology to ensure equal lengths and in-phase wave fronts from the diaphragm to the horn mouth, which increases the output sound pressure and facilitates simple speaker angle adjustment, making the live sound more uniform and covering a wider area. Wide factory. The sound quality is delicate and transparent, and the loudspeaker pressure is not distorted. The outer layer is made of 18MM thick birch plywood and sprayed with wear-resistant matte black paint, and the surface mesh is pasted with a high sound transmittance acoustic sponge to prevent the erosion of dust and rain.

LA28B is a built-in two 18" high-efficiency subwoofer system that can be used as a passive bass extension for LA-312/LA-212.

Applies to:

Small and medium-sized performances, outdoor sound reinforcement, auditorium conference room sound reinforcement and other places.
