SEAPRO (Senbao) LA212/SUB is a high performance dual 18 "subwoofer designed to extend the low frequency LA212 in some large-scale performances, but also used.LA212/SUB and LA212 requirements must have low frequency sound box hoisting hoisting system of the same, in actual use with LA212 quickly and safely in hoisting together.                      

LA212/SUB uses 2 "18 long stroke high-power unit, installed in the coupling horn cavity, inverted phase hole is designed on both sides of the box, so as to ensure the high pressure output, but also has very low frequency. The interior of the box adopts a multiple strengthening structure to fully reduce the energy loss caused by the resonance of the box body, making the low frequency of the high-power loud pressure state more strong and impact force.                      

The LA212/SUB box is made of high strength composite plywood manufacturing birch is installed, double handle safety ergonomics structure for ease of handling, the surface spraying waterproof scratch high hardness resin paint. Unit surface spray waterproof coating, high strength steel net post waterproof waterproof acoustic sponge, connection socket adopts high strength waterproof dustproof aviation socket. LA212/SUB is the best choice for mobile performance bass.                      

LA212/SUB box surface mounted by precision aluminum alloy lifting body, the actual use can be placed on the ground can also be hoisted.
