Styled in dark gray, the Genelec W371A SAM Woofer System is designed to add vital low end to Genelec SAM Series 8341, 8351, or 8361 (the Ones) coaxial nearfield monitors. This is not a subwoofer, per se, but a free-standing woofer system meant to be used in pairs to provide the user with a directional, full-range monitoring system. With a full-range monitoring system at your disposal, it will be far easier to make critical decisions on your mix or post-production project.
