The MCS-860VS ceiling subwoofer from MINKEZ is a great option for commercial and industrial uses. For instance, background music and paging in hotels, businesses, schools, and factories. This public address system with a 250mm cutout speaker provides a range of SPL 90dB and a wide frequency response of 60-2kHz to meet different venue sizes. Additionally, the power taps make it simple to change the input from 100V to 70V or 8V, allowing this speaker to work with both high and low impedance inputs. The ABS back cover, ABS baffle, and metal grille are all painted a pleasant shade of white.
