The SF-20A is a high definition, mid-high unit which is part of the SF-Monitor system. The powered SF-20A can also be used individually to provide additional reach in areas not covered by the main Sound Force system. The mid range incorporates the optimized 12AN4 neodymium loudspeaker providing high output and reliability. High frequency response relies on a compression driver-waveguide assembly which employs the M-75N neodymium compression driver. Two aluminum assemblies attached to the front of the cabinet comprise the high frequency waveguide and the carrier for the 12” woofer. The rear of the SF-20A is dominated by an aluminum heat sink housing the powerful Class D amplifier and related electronics.
A new stacking system allows the SF-20A to be mounted on the SF-1521A companion subwoofer and angled at the DJ´s preference.
