LAM1432SA is specifically designed as a planar waveguide active speaker system to enhance the performance of LAM1432 low-frequency speakers. This advanced system features an 18" unit with a 100mm voice coil for extended range and precision. The LAM1432SA comes with an all-steel suspension system, allowing for convenient stacking or suspension alongside LAM1432 speakers. The speaker box is constructed from 13 layers of sturdy plywood and treated with wear-resistant yarn points to ensure durability. Equipped with a three-channel digital power amplifier module, the LAM1432SA can effortlessly power one LAM1432SA and two LAM1432 speakers concurrently. Additionally, it incorporates a DSP digital audio processing module with one input and three outputs for accurate sound adjustments, and it supports RS485 connection to a computer for convenient system parameter adjustments.
It is worth noting that in this combined system, the LAM1432 uses all-neodymium Celestion units from the UK, delivering clear, detailed, and natural sound. The LAM1432SA features an 18-inch Celestion low-frequency driver with a 100 mm voice coil and 220 mm magnetic circuit, producing powerful, stable bass. Its built-in German-engineered amplifier and original German DSP processor ensure precise signal processing, system stability, and wide dynamic range. Together, they form an upgraded system that delivers high-quality, detailed, and layered sound.
