LA212低频音箱扩展始终保持着RISE AUDIO特有的声音学特性宗旨，它们适用于所有需要低频扩声系统扩展使用。
LA212音箱使用18mm多层优质桦木夹板材质，内部同时根据不同之强化处理使音箱能够承受低频单元的更强冲击力。音箱表现涂有一层抗撞漆，音箱前面板用坚固的金属网格作为保护，箱体的两侧都设计有人工力学型把手设计，搬运更加方便。
LA212音箱单元采用专利的双音圈差分驱动技术和高峰值对峰值偏移技术，能展观出真正、完美的超低频声音，大型的环状散热设计使散热效能大大加强，保证了驱动单元的运行温度低，大大地提高了功率压缩的性能和减少诣波失真。LA212低频音箱能提供干净、深沉、具有爆发力的低频声音效果。
