Line array main sound amplifying sound box
2 x 12 "(305mm) neodymium magnetically efficient water proof bass unit

1 * 10 "(260mm) neodymium magnetic water proof medium sound unit

3 x 1.7 "(44mm) neodymium magnetic soprano unit

The box is made of 18 mm birch splint. The surface is treated with black abrasion resistant spray paint.

80 degree x 7 degree coverage angle design with uniform and smooth axial and axial responses.

The appearance of avant-garde can be superimposed with more than one speaker.

The JHL-312 speaker adopts an external three frequency division design, a 2*12 "low frequency drive unit, 1 10" medium frequency drive units and 3 1.7 "high frequency compression drive units and a waveguide tube. The hanger is designed by acoustic design to hang JHL-312 into a vertical column. The number of hanger is more than 24, and the angle of vertical coordination of the sound box is adjustable from 0 to 7 degrees, and each can be adjusted to 1 degrees. The cylindrical wave forms a good coupling on the vertical plane. Because the low frequency driver is in a very sound arrangement. Making the excellent 80 degree horizontal diffusion call the lower limit to 100Hz. JHL-312 is used for hanging parts and acoustic design in conjunction with JHL-218W speakers. JHL-312 can form a linear array of systems independently. Or more than one JHL-218W loudspeaker system. JHL-312 speakers use birch multilayer splint, anti-collision, sunscreen paint. The front panel of the speaker is protected by steel mesh and sponge, and the rear side plate is combined with 4 handles. The rear panel is two NL4MP input interfaces. The JHL-312 is very compact and portable, with a peak power output of 142 dB and 1 m. It can be used as a main speaker or overlay horizontally or vertically. Applications include A/V speech, small to large main sound reinforcement system.
