超小型、DSP控制的双放大近场监听
带DSP的音箱已经逐渐从高不可攀成为走入寻常录音棚的标配。Neumann也是首次将DSP技术应用在了小尺寸的KH系列监听音箱上，KH 80 DSP配备4英寸低音单元和1英寸高音单元，分别是120W和70W功率，频响57Hz到21kHz（+/-3 dB），最大声压级108.8dB：
KH 80 DSP的背后接口，除了传统的卡农输入，还多了RJ45网络接口，连接电脑后可以启动Neumann.Control软件对KH 80 DSP的DSP算法做各种调节：
KH 80 DSP监听音箱，使用了数字信号处理以确保声音品质。利用手机的App Neumann.Control则可以自动调整扬声器系统。
KH 80 DSP监听音箱除了黑色版，也推出了白色版，适合小清新风格的录音棚、发烧友、有特殊需求的安装系统或家用。
KH 80 DSP有着跟大型Neumann监听型号一样创新的数学模型分散波导设计，可以确保更宽的横向范围和更窄的纵向范围，以让监听音箱适合各种声学环境即便在离轴的情况下也有平滑的响应，更少的反射和更自由的移动可能性。
KH 80 DSP的箱体使用聚碳酸酯复合材料可以消除驻波，确保低频有着超快的瞬时响应。它还可以降低互调失真，特备是中频上的互调失真。前面板用整个一片材料制成，可以最小号衍射并确保有平滑的频率响应。两个大导向孔可以降低低频压缩。
KH 80 DSP是Neumann第一款内置DSP引擎的监听音箱。利用将在2018年初提供的手机的App Neumann.Control应用即可进行控制，以让其适应各种声学空间的使用。应用将指导你如何设置，你也可以手动设置。
出厂的时候每一只KH 80 DSP都确保可以与规定的线性频响曲线对齐，也就是说当你成对使用的时候它们都是完全可以保持匹配的。
