Alpha-F8+Alpha-S1812 Passive Line Array Speaker system

Alpha-F8 Overview 

The compact Alpha-F8 linear array speaker is used to form a vertical array. Adopting a passive external two-way design, two 8" drive units are arranged in a dipole arrangement, and a 1.4" compression drive unit with inverter is installed in the center. The precise horn geometry combined with the advanced bass reflex inverted hole design produces the directivity control capability of the frequency bandwidth and expands the low frequency output. This high-performance linear array module can provide a controllable 80° horizontal direction as low as 500Hz. Its mechanical and acoustic design can ensure a vertical array of up to twenty-four speakers, and the vertical inclination can be adjusted between 0° and 14° with an accuracy of 1°. This speaker can be combined with Alpha-F1812 speakers to form a vertical array. The speaker cabinet adopts waterproof plywood, impact resistant and open-air protective paint PCP (polyurea cabinet protective paint). The front panel of the cabinet is protected by a solid metal mesh and lined with waterproof and sound-permeable cotton. Each side panel is equipped with a handle. The box is equipped with a three-point hoisting device.

Alpha-F1812 Overview

Alpha-S1812 is an active cardioid subwoofer with single amplifier channel driving. The speaker has two built-in long-stroke neodymium drive units arranged in a heart shape. The 18" drive unit in the low-frequency reflector box faces the front and a 12" two-chamber bandpass design drive unit faces the rear. The cardioid diffusion pattern produced by this configuration can prevent energy from radiating to the rear of the system, provide extremely high low frequency reproduction accuracy, and reduce energy loss in excess areas. Alpha-S1812 is equipped with a three-point hoisting device, which can be completely vertical to the Alpha-F8 full-range speaker array, hoisted on the top of the Alpha-F8 speaker array, or used for ground stacking. This speaker can form a vertical array with Alpha-F8 speakers. The speaker cabinet adopts waterproof plywood, impact resistant and open-air protective paint PCP (polyurea cabinet protective paint). The front panel of the box is protected by a solid metal mesh and lined with waterproof sound-permeable cotton. The side panel is fixed with four handles.
