M-518A/M-918A is a planar waveguide active speaker system specially designed for A3M's low-frequency supplement. M-518A consists of an 18-inch 100mm voice coil 220 magnetic long-stroke unit.

M-918A is composed of an imported neodymium magnet unit.

M-518A/M-918A adopts an all-aluminum suspension system, which can be stacked or suspended with A3M. There is an M20 connector on the top of the box. One or two M-518A/M-918A can be supported to a certain height through MD2. The body is made of 13-layer plywood, and the surface is treated with wear-resistant and waterproof polyurea.

M-518A/M-918A has a built-in 1800W digital power amplifier module to drive the low frequency and high frequency separately. A one-in and two-out DSP digital audio processor module is used for tone correction, and the system parameters can be adjusted by connecting to the computer via wifi. The power amplifier module has an LCD display.

It is suitable for small mobile performances, gymnasiums, theaters, bars, banquet halls and other places.
