The 8351A combines our breakthrough Acoustically Concealed Woofers (ACW™) technology together with our Minimum Diffraction Coaxial (MDC™) driver and Maximised Directivity Control Waveguide (MaxDCW™) to produce controlled directivity over a very wide bandwidth. Genelec Loudspeaker Manager (GLM™ 2.0) computer control allows for repeatable, consistent performance over flexible proprietary network. Genelec AutoCal™ measures and automatically aligns every monitor on the network for level, timing, and equalisation of room response anomalies.
